Colorado DMV Practice Test 2024

The implied consent law in Colorado says that by getting behind the wheel, you have already given consent (i.e. answered "yes") to allow a blood, breath, or urine test if requested by a law enforcement officer. Refusing a police breath/chemical test is a serious offense and will result in license suspension.

Drivers must not drive on or over the legal Colorado BAC limit of 0.08! If you are above 0.05 BAC but below 0.08, it may count as "permissible inference that person was driving while impaired". If you suspect you are close to the limit, do not drive! Also, even a low BAC may impact your driving drastically so refrain from driving if you feel affected in any way.

Drivers under 21 face stricter rules than older drivers in Colorado and may be convicted of a DUI with a blood alcohol concentration of .02 or higher.

High beam headlights will temporarily blind other drivers if used the wrong way. In Colorado, you are required to dim your light to low beam if (1) within 500 feet of an oncoming vehicle or (2) within 200 feet of a vehicle traveling in your direction. High beams should also not be used in fog.

High beams should also not be used in fog.

Hazard light use is not permitted while driving in Colorado, except if the vehicle is driving slower than 25 mph.

The Colorado move-over-law is designed to protect emergency personnel and workers. If approaching a stationary emergency response vehicle with flashing lights, including utility- and maintenance vehicles and tow trucks, you must vacate the lane closest to the stopped vehicle. If changing lanes is unsafe or not possible, you must slow down to a safe and prudent speed for the conditions.

You should always maintain a following distance of at least 3 seconds to the vehicle in front of you according to the "three-second rule" used in Colorado. In bad conditions and at higher speeds, you should consider increasing the following distance to 4-5 seconds so you have time to safely stop if necessary. On slippery roads, it may be necessary to increase the following distance even more.

In Colorado, the standard speed limit in residential areas is 30 mph unless signs indicate otherwise.

In Colorado, the standard speed limit in a business district is 25 mph unless signs indicate otherwise.

A solid line on your side of the road indicates that passing is prohibited. In this picture, you are NOT allowed to pass as you will need to cross double solid yellow lines.

It’s the drivers' responsibility to drive legally and safely. 

Don’t let your passengers negatively affect your driving or distract you. Instead, you can ask your passengers to ease your driving by e.g. helping you identify potential hazards, acting as navigators, or helping you change music.

This sign warns you that the right lane is ending. Vehicles in the right lane must merge left.

Rear-end collisions stand for a large sum of all traffic accidents, and they can often be avoided by keeping a sufficient following distance. Increase the following distance when driving at night or in bad conditions.

Drivers must yield to pedestrians when entering or exiting a roundabout. If the pedestrian is carrying a white cane or being led by a guide dog, he/she is likely blind - give blind pedestrians a wide berth and priority in every situation! 

Before entering the roundabout, also yield to vehicles already in the roundabout. 

With just one working headlight, it will be difficult to know if the oncoming vehicle is a bicyclist, a motorcyclist or a car. 

It’s especially dangerous if the remaining functioning headlight is the right light, as it can trick you into thinking that the vehicle is driving further to the right than it actually is.

This sign indicates the recommended speed for this curve is 40 mph in good conditions. Consider slowing down even more in poor weather conditions.

It’s very dangerous to drive when tired. While listening to music and rolling down the car windows can help a little, it won’t prevent fatigue. What helps is rest - so pull over and rest until you no longer feel tired.

Headlights help increase visibility by either providing you with more light, or helping other drivers see you. They help counter the limited vision on mountain roads and as a consequence reduce the chance of a collision.
