Missouri DOR Practice Test 2025

A common fault when turning is failing to signal properly, leading to many crashes each year in Missouri. You should signal for at least 100 feet before any turn.

A red ‘X’ means that the lane is closed for traffic and that you should change lanes immediately. These lights are used over reversible lanes in Missouri to help drivers determine which lanes are open or closed and are often accompanied by double-dashed yellow lines. Reversible lanes are designed to help with rush hour traffic by carrying inbound traffic during the morning peak hours and outbound traffic during evening peak hours.

All school buses, vehicles carrying passengers for hire, and vehicles transporting hazardous material must stop at all railroad crossings in Missouri. If you are driving behind any of these vehicles, you should be prepared to stop as well.

Before proceeding at an intersection, you're always required to yield to traffic already in the intersection. This applies even if you're facing a green light.

Exchange your name, address, driver's license information, insurance information and phone number with anyone else involved in the crash. After exchanging information, write down as much information about the crash as possible. This includes weather conditions, road conditions, time of the crash, and how the crash occurred. This will help determine who is at fault and help with insurance claims. Crashes in Missouri must be reported in incidents of injury, fatality, or vehicle- or property damage exceeding $500. The deadline to file the report is 5 days.

If the turn can be made safely, you may turn right on a red light in Missouri after coming to a complete stop and yielding to any pedestrians/vehicles lawfully proceeding through the intersection. Look for signs that prohibit the turn.

If you crash into an unattended vehicle, you're expected to make a reasonable attempt to locate the owner of the vehicle. If unable to locate the owner, you should instead leave a note in a secure place with your contact information and details regarding the crash. In additon, you should take pictures of the scene (including damage to the other car and their license plate number), and notify your insurance company as well as the nearest police department about the accident. Crashes in Missouri must be reported in incidents of injury, fatality, or vehicle- or property damage exceeding $500. The deadline to file the report is 5 days.

In Missouri, there is no prohibition on wearing headsets while driving. However, you should be very careful about covering your ears entirely as you will miss the visual queues otherwise present in the road environment.

Many states allow drivers to turn left from a one-way street onto another one-way street, but that is not the case in Missouri. In Missouri, you must not turn left on red under any circumstances.

Texting while driving is prohibited in Missouri for drivers 21 and under. This is because any such use will severely distract you and increase the risk of a crash. Even if you are older than 21, it's recommended that you pull off the road and stop if you need to text someone or make a call. Never use a phone when driving in hazardous conditions as you must focus all your attention on driving.

The standard speed limit in any city, town or village in Missouri is 25 mph unless signs indicate otherwise.

The standard speed limit on rural interstates and freeways in Missouri is 70 mph. The standard speed limit applies if there aren't any speed limit signs posted.

Whiplash injuries occur when the neck is thrown back and forth in a collision, which causes injury to the neck muscles. It’s a common injury mainly caused by being hit from behind (rear-end accidents).

Minimum speed limit signs ensure that drivers don’t drive too slowly i.e. at a speed that halts the traffic flow and/or creates a dangerous road environment. This helps keep a smooth traffic flow and congestion to a minimum. Try to keep up with the traffic flow even when there aren’t any minimum speed limit signs.

Look all around before and during the maneuver. Stop and yield to any pedestrians who want to cross behind you. Avoid waving them across or giving any other signals that could mislead them and create a dangerous situation.

This is an example of a so-called "blind intersection" where your view of oncoming traffic is blocked. As you can't see other traffic, you want to proceed carefully until you have a clear view of the intersecting roads. Keep the front wheels out of the cross lanes as you edge forward.

You are crossing a one way street and may only turn in the direction of the arrow.

Keep to the right and prepare for two-way traffic ahead.

If you are being tailgated, you should allow for the tailgater to pass by slowing down and/or changing lanes. Lightly tap your brakes a couple of times to warn the tailgater that you are about to slow down. 

Consider pulling over to let the tailgater pass if you’re driving on a two-lane road where passing is prohibited.

You can never be sure that other drivers will slow down in time to let you back into your lane. Never pass unless certain that you have enough time and distance to complete the maneuver safely.
