Questions

Air Brakes

How long is the brake lag distance when traveling 45 mph under good conditions?

27 feet

B37 feet

C55 feet

D20 feet

The brake lag is the extra distance traveled before the air brakes begin to work. At 45 mph, 1/2 second of brake lag equals 27 feet. As the total stopping distance at 45 mph is 346 feet, the brake lag distance is just under 10% of the total distance traveled.

How do you test the service brake stopping action?

Drive at around 5 mph and push the brake pedal firmly

BDrive at around 20 mph and push the brake pedal firmly

CPush the brake pedal while standing still, see if it feels "normal" as you push it

DDrive at around 35 mph and push the brake pedal firmly

The best and proper way to test the service brake stopping action is to push the brake pedal firmly at a low speed. If it pulls to one side or the other or the braking feels delayed, there might be an underlying problem. If you speed up too much as you test the service brakes, you won't be able to stop if they do not function correctly.

Why must the emergency and parking brake use a mechanical force rather than air pressure or hydraulic fluids?

AAs air pressure becomes less effective in warm weather

BAs air pressure becomes less effective in cold weather

As a mechanical force cannot leak

Air pressure or hydraulic fluids can leak while a mechanical force (such as a spring) cannot. For this reason, the emergency and parking brakes must use a mechanical force like a spring brake so that a leak won't remove the braking capability.

How should you use brakes on a long and steep decline?

As a supplement to the braking effect from engine braking

BBy constant braking

CBy using them as the main braking component over the braking effect from engine braking

The proper braking technique for a long and/or steep downgrade is to use the brakes as a supplement to the braking effect of the engine when driving on a low gear. It is very important to avoid the brakes overheating and losing all function.

To properly brake without causing brake fade by overheating the brakes: use the proper low gear and then apply the brakes only enough to feel a definite slowdown. Once your brakes are approximately 5 mph below the "safe speed", release the brakes over 3-seconds. These steps should be repeated once your vehicle reaches the "safe speed".

What can make the spring brakes less effective?

Unadjusted service brakes

BLow tire-pressure

CA heavy load

The combined pressure of the springs and air pressure could damage the brakes.

While many new brake systems are designed to remove this danger entirely, the problem still exists in many existing vehicles. The best way to avoid damaging the brakes is to develop a habit of not pushing down the brakes when the spring brakes are activated.

Combination Vehicles

Off-tracking is:

AWhen the front wheels move off the paved part of the road

BWhen the front wheels follow a shorter path across a turn than the rear wheels

CWhen the rear wheels move off the paved part of the road

When the rear wheels follow a shorter path across a turn than the front wheels

Off-tracking is when your rear wheels follow a slightly shorter path across the turn than the front wheels. To combat off-tracking, you need to steer the front end wide enough around a corner so the rear end will stay on the road.

Which of the following is true in regards to turning a large vehicle?

AThe tractor should turn close to the curb

The last trailer will off-track the most

CTurning wide using multiple lanes is prohibited

DWhen the front wheels move off the paved part of the road

The rear wheels will follow a slightly shorter, more direct, path across the turn than the front wheels, called "off-tracking". As a result, long tractors with trailers must turn wider than other vehicles to avoid having the rear end run over the curb. The longer the vehicle is, the more the rear wheels will off-track. To combat off-tracking, you need to steer the front end wide enough around a corner so the rear end will stay on the road. If you need to use multiple lanes to turn, you may do so.

Why is it very important to correctly lock the latch when coupling a pintle hook?

AFailure may lead to an air pressure drop in the brake system

BFailure may lead to the emergency brakes being activated

CFailure may lead to the brake system not working correctly

Failure may lead to separation of the trailer and vehicle

Lock the latch correctly! If you don't, the trailer and vehicle can separate.

Will all rigs be coupled and uncoupled in the same way?

AYes

There will be differences in the coupling and uncoupling procedure depending on the truck(s) you drive. Learn what sets each truck apart and what procedure to follow for each truck you drive.

If you mistakenly connect the wrong glad hands to each other on a vehicle without spring brakes:

AYou won't get air to the tractor

BYou will be able to brake but not drive

CYou won't be able to drive off

You will be able to drive but not brake

If you mistakenly cross lines on a vehicle without spring brakes by, for example, attaching the service line to the emergency line, you will be able to drive just fine but the trailer brakes won't work. You will only notice this when you try to brake, which can be very dangerous. To prevent driving without working trailer brakes, always test the trailer brakes before driving off.

Double/Triple Trailers

You uncouple the triple-trailer rig by:

Pulling the dolly out and then unhitching the dolly

BKeeping the dolly in place and uncoupling as you would any double-bottom rig

You want to pull the dolly out before unhitching. If you unlock the pintle hook with the dolly in place under the trailer, the dolly tow bar may fly up and injure you and others. After you have pulled out the dolly, you can uncouple the remainder of the rig just as you would any double-bottom rig.

If you want to connect the converter hook to the front trailer:

AReverse the first semitrailer into place in front of the dolly tongue

BHook the dolly to the front trailer

CLock the pintle hook and secure the converter gear support in the raised position

All of the above

To connect the converter hook to the front trailer, you first need to position the first semitrailer into a position in front of the dolly trailer. Then, you'll hook the dolly to the front trailer by locking the pintle hook and securing the converter gear support (should be in a raised position).

Which of the following is NOT part of the additional check you need to do for double/triple trailers before you drive?

AMake sure the pintle hook is latched

BMake sure the safety chains are secured

CMake sure the light cords are connected to the sockets

Make sure the rear converter dolly air tank drain valve is open

There are additional checks for double/triple trailers in addition to the checks that must be done for other combination vehicles. Among those are making sure the pintle hook is latched, that the safety chains are secured and the light cords are connected to their sockets on each trailer. The rear converter dolly air tank drain valve should be CLOSED, not open.

Which of the following is not part of uncoupling the converter dolly?

ALowering the landing gear

BApplying the spring brakes or chocking the wheels

CReleasing the pintle hook on the first semi-trailer

Connecting the safety chains

To uncouple the converter dolly, you'll first want to lower the dolly landing gear (so it can handle its own weight) and then hold it in place by applying the converter gear spring brakes or chocking the wheels. Then, you'll disconnect the safety chains, release the pintle hook on the first semi-trailer, and gently pull clear of the dolly.

Do not unlock the pintle hook when the dolly is under the rear trailer. It may put pressure on the dolly tow bar and cause it to fly off.

You release the dolly brakes by:

Opening the air tank petcock

BClosing the air tank petcock

To manually position the converter dolly in front of the second trailer or pick it up with the tractor, you will first need to release the dolly brakes. You can release the dolly brakes by opening the air tank petcock, or by using the dolly parking brake control on a dolly with spring brakes.

General Knowledge

How many people are killed each year on U.S. roadways because of distracted driving?

AApproximately 2,500

Approximately 5,500

CApproximately 7,500

DApproximately 15,500

The National Highway Traffic Safety Administration (NHTSA) estimated that 5,500 people are killed each year on U.S. roadways because of distracted driving, and an additional.450,000 are injured.

After a vehicle inspection, the motor carrier has to:

Repair any items that may affect safety

BRepair any item that were found during the vehicle inspection

CRepair only selected items deemed necessary

The motor carrier must repair any items that may affect safety before letting the vehicle be used, or explain why a repair was unnecessary. If the defects have been repaired or you consider the reason to not repair to be satisfactory, you can sign the prevois driver's report. As soon as you get behind the wheel and start driving, you are responsible for the safe operation of the vehicle.

The average perception time for an alert driver is:

A1 second

1 3/4 seconds

C2 3/4 seconds

D2 seconds

For an average alert driver it takes 1 3/4 seconds for their brain to recognize a hazard, and even longer before they hit the brakes. 1 3/4 seconds is 117 feet at 45 mph.

What is Gross Vehicle Weight Rating (GVWR)?

AThe total weight of a single vehicle including its load

BThe total weight of a combination of vehicles including the load

The value specified by the manufacturer as the loaded weight of a single vehicle

DThe value specified by the manufacturer as the loaded weight of a combination vehicle

You must know how much weight your vehicle can handle to avoid overloading it. Gross Vehicle Weight Rating (GVWR) is the value specified by the manufacturer as the loaded weight of a single vehicle.

At a crash scene, what can you do to help a person who’s unconscious?

ATake photos of the scene

Check that the person is breathing normally

CSplash water on his/her face

If you notice that a person is unconscious, you need to check that he/she is breathing normally. Look and listen for breathing, look for chest movements, and feel for breath on your cheek.

Hazardous Materials

What is outage or ullage?

The amount a liquid tank falls short of being full

BThe amount a gas tank falls short of being full

CThe amount of excess fuel the HazMat vehicle must have for safe transportation

DThe max. amount of explosives that may be carried on a specific HazMat vehicle

Liquids in a cargo tank will expand as the temperature changes during transit. To prevent the tank from becoming too full, every tank carrying liquids has to be empty to some percentage, i.e. the amount of outage or ullage needed. How much outage or ullage that is needed will depend on the liquid being transported, but there must be enough outage so the tank will not be full at 130 degrees Fahrenheit.

The role of a professional driver at the scene of an accident is to:

ACommunicate the danger of HazMat to emergency personnel

BProvide emergency personnel with the shipping papers and emergency response information

CMake sure people stay away

All of the above

At the scene of an accident, it is your job to keep others away from the dangerous accident scene and to communicate the danger to emergency personnel and to provide them with the shipping papers and emergency response information that enables them to do their job.

What should you do if asked to load Division 6.1 (cyanides) with 10 pounds of acid?

ALoad them on opposite ends of the cargo

BLoad them close to each other

Inform them that these products must be loaded in different cargo spaces

Division 6.1 (cyanides) must not be loaded in the same cargo space as any acids, corrosive materials, or other acidic materials that may release hydrocyanic acid. If asked to load these together, inform the person in charge that these must not be loaded together.

What do you need to know to decide which placards to use?

AThe weight of all classes of HazMat being transported

BThe amount of each hazard being transported

CThe hazard class of the materials being transported

All of the above

By knowing the weight of all classes of HazMat being transported, the amount of each hazard, and the hazard class of the materials you can then decide which placard to use on your vehicle.

A transport index:

Shows how close you can load Class 7 (radioactive materials) to other materials

BShows the recommended materials to transport with packages of Class 7 (radioactive materials)

CShows the height and width of the package

The transport index is used on radioactive materials to show the degree of control needed during transportation, which means how close to other objects it may be placed. The transport index will depend on the radioactivity of the material in question.

Passenger Vehicles

Are riders allowed to leave carry-on baggage in the aisle?

AYes

The aisle and doorways should be clear of baggage. In an emergency, misplaced bags in the doorways or aisles can be very dangerous as they will make a safe evacuation much harder. Secure bagge and freight in a safe place that does not damage the cargo.

The driver and all riders must be able to use all exits and not have their movement restricted due to bags or freight.

You are driving and notice your seating position is uncomfortable. When should you adjust your seating position?

AImmediately

At the next stop

CAfter dropping off all passengers

It's important that you driver's seat is comfortable and correctly adjusted. If you notice that the driver's seat is uncomfortable while transporting passengers, do not adjust the seat immediately. Do it when at the next stop. The reason you don't want to adjust the seat while driving is that it takes your attention away from driving.

You come upon a drawbridge with a green traffic light. What should you do?

Proceed slowly and make sure the drawbridge is safe to cross

BProceed at normal speed

CStop before the drawbridge and manually inspect the bridge to make sure it is safe to cross

If you come upon a drawbridge with a green traffic light, you may proceed. However, you should still slow down to make sure it is safe and the draw of the bridge is closed. It's very important to be aware that the traffic lights can malfunction. If there are no traffic control signals at all, you need to stop at least 50 feet before the draw of the bridge and make sure the draw of the bridge is closed.

What do you have to inspect the emergency exits for during the pre-trip inspection?

AEmergency exits should operate smoothly, close securely from the inside, and be without damage

BThe release handle of an emergency exit should be operated properly from both inside and outside the school bus

CRed lights or other emergency exit warning devices must be working properly

All of the above

Emergency exits must be able to be used properly in case of an emergency. During the pre-trip inspection test, you will need to demonstrate that a minimum 1 emergency exit can be operated smoothly, can close securely from the inside, and is without damage. You also need to make sure that all exit warning devices, such as red lights over the exits, are working properly. The release handle must be able to be operated properly from both the inside and outside of the bus.

You must review the inspection report made by the previous driver:

Every time before you drive

BAt the start of each new month

CAt the start of each new week

You must know that the bus you will be driving is safe. As part of the pre-trip inspection, you must review the inspection report made by the previous driver before you drive. Only drive the bus if safe.

You should only sign the previous driver's report if all defects reported have been certified as repaired or repairs not needed.

Pre-Trip Inspection

How can you make sure the locking jaws are functioning properly?

ABy driving the vehicle quickly forward and testing the locking jaws

BBy feeling with your hand inside the fifth-wheel gap to check that the locking jaws are closed around the kingpin

By looking into the fifth-wheel gap to see that the locking jaws are closed around the kingpin

You need to make sure the locking jaws are without damage and fully closed around the kingpin. Never put your hand inside the fifth-wheel gap as the weight can shift and crush your hand. Instead, look int othe fifth-wheel gap and visually check that the locking jaws have closed around the kingpin.

What are some optional emergency items you should have in the truck and check for during the vehicle inspection?

ATire-changing equipment

BEmergency phone number(s)

CAccident reporting kit

All of the above

These are all optional emergency items that are nice-to-have but optional. Check for them so you will know where to find them if you do end up having to use them.

As you approach the vehicle, look for:

AVisible damage

BCoolant, oil, grease or fuel under the vehicle

CThe vehicle leaning to one side or the other

All of the above

As you approach the vehicle to make an inspection, you should notice the general condition of the vehicle. If it is damage or leaning to one side, you will need to take extra care to check that the vehicle is safe to drive. You also want to check for leaks or fresh fluids under the vehicle.

In a static leakage test:

You will check the level of leakage when the brakes are not applied

BYou will check the level of leakage when the brakes are applied

The static leakage test is done by charging the air system fully, then turning the engine off and releasing all the brakes. In 1 minute, the air pressure should drop no more than 2 psi for single vehicle, 3 psi for a combination of 2 vehicles, or 5 for a combination of 3 or more vehicles.

Any loss greater than the above mentioned indicates a problem in the braking system. The static leakage test is not usually part of the vehicle inspection test, but you may be asked to perform the test by the examiner.

Which of these alternatives do you NOT have to check when inspecting the steering system?

ASteering box - the box must be securely mounted, without missing parts, and not leaking

BSteering hoses - look for damage to the power steering hoses or power steering fluid leaks

CSteering linkage - all connecting links, arms, rods etc. must be present and not cracked or worn

Steering wheel - must not be frayed or look worn

A frayed steering wheel does not guarantee the steering is bad, but it indicates you should take a good look at all cables, hoses, etc. in the steering box. You should make sure the steering box is securely mounted, without any leaks, and that any steering linkage or hoses are in good shape. Inspect the connecting links, arms, rods, etc. from the steering box, including joints and sockets, power steering hoses, and look for damage or wear that could affect steering.

School Bus

You are preparing to leave after unloading students. When should the alternating flashing red lights be turned off?

Just before you pull away from the unloading area

BAs soon as you have unloaded the students

CApproximately 100 feet after you have started driving again

Alternating flashing red lights are used to indicate to approaching drivers that they must stop. As soon as you turn the lights off, drivers will begin to pass the school bus again. You should only turn the lights off after you have finished unloading the students and all students are accounted for. Turn them off just as you prepare to leave - but after you have made sure no students are returning to the bus, no students are in the danger zones, and all students are safe.

You have finished your route. Why should you walk through the school bus before leaving it?

ATo look for sleeping students

BTo look for stuff left on the bus

CTo look for vandalism and open windows or doors

All of the above

As part of the post-trip inspection, you need to walk through the school bus and ensure that there are no sleeping students, articles left on the bus, damage/vandalism, or opened widows or doors. Report any issues to a school official immediately.

How will you know that something is not working with the ABS?

AThe ABS-lamp comes on at start-up

The ABS-lamp stays on after bulb-check

Vehicles with ABS have a yellow ABS malfunction lamp to indicate if something is wrong. The lamp will come on at start-up briefly for a bulb check, but it should go out quickly - on older vehicles, it may stay on until you drive faster than 5 mph. If the light stays on, you may have lost ABS-control.

Which of the following is NOT part of the unloading procedures on a route?

Ask students to walk 5 feet away from the bus

BCount all students in the bus so you can keep track of how many students are leaving / entering the bus

CAccount for all students before you leave

DEnsure all students remain seated until told to exit

The unloading procedures along the school bus route are often different than the unloading procedures at school. To unload along a route, you need to keep track of the number of students in the bus at all times. By counting the number of students on the bus, and the students leaving, you will be able to monitor their movements and ensure that you can safely locate each student before you move off.

You should ask the unloaded students to move at least 10 feet away from the bus and stand in a position where you can clearly see all students. If you cannot account for a student, you will have to secure the bus and search in, under and around the school bus before you proceed.

What happens to the normal brake function if the ABS fails?

It will remain unchanged

BIt will be worse

CThe brakes won't work

In case of ABS failure, the brakes will still work but you won't be able to use the anti-lock braking system in case of emergency braking. This can often be seen by the ABS warning lights - if the light is activated beyond for longer than it should be, have the ABS fixed as soon as possible!

Tanker Vehicles

Can all tank vehicles be inspected in the same way?

AYes

Unfortunately, tank vehicles can come in many different configurations. To know how to inspect your tank vehicle, you need to read the vehicle's operator manual.

Tank vehicles with liquid are especially _____ to roll over.

Easy

BDifficult

A liquid tanker will have a high center of gravity because the load's weight is carried high off the ground. A high center of gravity means the vehicle is top-heavy and especially likely to roll over. Liquid tankers can even roll over in a curve when driving at the posted speed limit. When driving a liquid tanker, slow down well below the posted speed limit before curves. Also be careful when changing lanes due to side-to-side surge of the liquid.

What is considered "enough outage"?

AWhen the tank will not be full at 50 degrees Fahrenheit

BWhen the tank will not be full at 80 degrees Fahrenheit

CWhen the tank will not be full at 110 degrees Fahrenheit

When the tank will not be full at 130 degrees Fahrenheit

Different materials will expand at different rates, but the general guideline for "enough outage" is when the tank will not be full at 130 degrees Fahrenheit. Read about local and state outage guidelines before you transport any liquids.

A tank with baffles can still have a strong:

ABack-to-front surge

Side-to-side surge

Baffled tanks are liquid tanks that are divided into several smaller tanks by the use of bulkheads with holes in them. The holes let the liquid flow through. This drastically reduces the back-to-front surge. However, baffles do not help with the the side-to-side surge.

What is a smooth bore tank?

ASmooth bore tanks have baffles inside that slow down the flow of the liquid

Smooth bore tanks is an unbaffled tank

Smooth bore tanks is another name for an unbaffled tank. Unbaffled tanks have no baffles inside to slow down the flow of the liquid, which means the back-to-front surge will be very strong. When driving an unbaffled tank you must be very careful as you start or start as the surge is likely to be very strong.

Why do unbaffled tanks exist if the relative surge is much stronger compared to baffled tanks? It's because some regulations forbid the use of baffles because the baffles makes the tank harder to clean properly. Food products such as milk etc. must be transported in an unbaffled tank because of sanitation regulations.

FAQ

How Do I Earn a Class A CDL in Oregon?

You will need a Class A CDL if you plan on driving any vehicle with a weight of over 26,000 pounds and a detachable trailer. This includes most tractor-trailers and semi-trucks. In addition to passing the general knowledge test, you will also need to take the combinations vehicle endorsement test. You will also need to pass a road skills test in a Class A qualified vehicle.

How Do I Earn a Class B CDL in Oregon?

A Class B CDL is required if you are going to be driving any vehicle that weighs more than 26,000 pounds and the trailer is not detachable, like trash trucks and most dump trucks. Because the trailer cannot detach you will not need to pass the additional combination vehicle endorsement exam, however, if your vehicle has air brakes, you will need to pass that endorsement test. You will also need to perform and pass your road skills test in a qualified Class B vehicle.

How Do I Earn a Class C CDL in Oregon?

Requirements for a Class C CDL depend entirely upon which type of vehicle you will be driving. For example:

If you are driving a passenger bus, you will need to take the passenger transport endorsement test.
If you’re driving a school bus, you will need the passenger transport endorsement as well as the school bus endorsement.
There is also a separate endorsement for hazmat vehicles, and you will need to provide whichever vehicle you intend to drive for your road test.

What Else Do I Need to Know About the Oregon CDL Manual and Test?

The Oregon CDL manual is based on the same template and federal regulations from the FMCSA (Federal Motor Carrier Safety Administration) that is used by all states. The CDL manual, test, and regulations are near identical across the US with only minor differences.
