Missouri CAR DMV Practice Test 20

This sign indicates that there is an intersection ahead. A road joins from the right.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow and black. This sign tells drivers that a lane is ending and that they should prepare to allow traffic to merge safely.

The only way to be sure you will have enough time to react to mistakes made by other drivers is to leave plenty of space between you and the vehicles around you.

The Missouri State Highway Patrol (MSHP) administers the driver examination. To find the testing center nearest you, contact the MSHP or the Department of Revenue.

To ensure your decision to be an organ donor, either enroll online or in person when applying for or renewing your permit or license. Completely fill out the back of your permit or license and inform your family.

Always be prepared to yield to any oncoming trains before crossing railroad tracks, particularly if there are no lights or gates controlling the crossing. Never start to cross the tracks until there is room for your entire vehicle on the other side of the tracks. Due to the risk of a vehicle stalling, it is not wise to shift gears when crossing railroad tracks.

A flashing red light means that you must come to a full stop, and then proceed when the way is clear.

Unless a posted sign prohibits it, you may turn right or left at a steady green light. When turning, you must yield to other vehicles and pedestrians within the intersection.

If a yellow panel with the message "Exit only" is on a highway sign, the lane below the sign will not continue through the interchange. Instead, the lane will go off of the roadway to form a ramp. If you are in a lane directly under an "Exit only" sign, you may change lanes to move through the interchange or you must exit the highway.

Driving more slowly than the flow of traffic can be hazardous. If you are on a two-lane, two-way road and driving so slowly that traffic is backing up behind you, you are required to pull off the road and let the other vehicles pass. Only drive significantly under the speed limit when conditions require it.

If you are being tailgated by another driver and there is a right lane, move over to the right. If there is no right lane, wait until the road ahead is clear and then reduce your speed slowly. This will encourage the tailgater to drive around you. Never slow down abruptly as this will only increase the risk of your vehicle being hit from behind.

You may never drive at speeds faster than 70 mph on Missouri's interstate highways. You may not drive more slowly than 40 mph on interstate highways, under normal roadway conditions.

This sign indicates that U-turns are prohibited.

If an aggressive driver cuts you off on the roadway, stay calm and get out of their way. Trying to get even with an aggressive driver risks escalating the situation and increasing the danger.

This sign means that you are approaching an upcoming intersection. Watch carefully for cross traffic.

Consuming any type of alcohol can have negative effects on your reflexes and judgment. It does not matter which type of alcohol is consumed, only how much alcohol has entered a person's bloodstream.

Warning signs are used to warn drivers about upcoming hazardous conditions and are usually yellow with black markings. This sign warns drivers that the road ahead curves to the right and then to the left.

When you are convicted of a traffic violation while your vehicle is in motion, the department receives notice and adds points to your driving record. You can lose your driving privilege when you accumulate too many points.

Even the most experienced drivers can be distracted while driving. A defensive driver looks out for the actions of other drivers and anticipates potential problems.

Any defect that may affect the safe operation of a vehicle should be corrected as soon as possible. Defects should be corrected before the vehicle is driven.

A solid red arrow in a traffic signal means the same thing as a circular red traffic light. When an arrow is red, traffic in the indicated lane must stop and may not turn in the direction that the arrow is pointing.

Warning signs are used to warn drivers about upcoming hazardous conditions and are usually yellow with black markings. This sign warns drivers that an upcoming bridge may be too narrow to meet or pass a truck and that they should be careful.

This advisory speed sign indicates the maximum safe speed for a highway exit (in this example, 30 mph).

Consuming both alcohol and another drug may enhance the effects of both. For example, taking one drink when you are also using a cold remedy could affect you as if you have had several drinks.

Never pass on the shoulder. Other drivers will not expect you to be there and may pull off the road without looking.
