Missouri CAR DMV Practice Test 23

You should turn your head to check your blind spots before every lane change.

When approaching railroad tracks, you should look, listen, slow down, and be prepared to stop for trains or other vehicles that may be using the rails.

Emotions can have a great effect on your driving ability. You may not be able to drive well if you are overly worried, excited, afraid, angry, or sad. Stress can lessen your concentration on the task of driving. It is better to wait to drive than to risk driving while you are emotionally unstable.

Be very cautious any time you encounter an animal on the roadway. Pass the animal slowly to avoid startling or frightening it.

Double solid yellow lines in the center of the road mean that passing is not allowed from either direction. You may not cross the lines unless you are making a left turn or passing pedestrians, bicyclists, and riders of scooters or skateboards when the opposite lane is clear and you can pass safely.

This sign warns of the presence of a crossroad ahead.

A steady yellow light indicates that a steady red light will soon appear. If you are driving toward an intersection and a yellow light appears, slow down and prepare to stop. If you are already within the intersection or cannot stop safely before entering the intersection, continue through carefully.

Railroad crossing warning signs are used to warn drivers of the possibility of a train. Drivers should obey all railroad crossing warning signs and never go around barriers or disregard the warning sign.

A "No standing" sign means that you may only make a temporary stop to load or discharge passengers.

Driving too fast for conditions is a major cause of motor vehicle crashes. Being inattentive to surroundings can cause a driver to collide with other vehicles. Most rear-end collisions are caused by drivers following other vehicles too closely.

You may cross a single broken line to pass or change lanes as long as you can do so safely and without interfering with traffic.

Persons who are upset, angry, or otherwise distracted by their emotions should take time to cool off before driving a car. Taking out frustrations or anger while driving is exercising very poor judgment and is very dangerous to both the driver and others on the road.

Distracted driving is extremely risky behavior that puts not only you and your passengers in danger, but also endangers pedestrians, bicyclists, and other motorists sharing the road. Focused attention on driving helps to prevent crashes.

You are required to stop at all railroad crossings when signals warn of an approaching train. These signals may include flashing red lights, a lowered crossing gate, a flagger signaling, or a train’s audible signal of warning. Do not attempt to go around a lowered gate.

If there is no stop line or crosswalk, you should stop at the point nearest to the intersecting roadway where you can get a view of approaching traffic. You should not enter the intersecting roadway to gain a better view.

When turning, you should reduce to a speed that allows you to maintain control of your vehicle, stay in your lane, and react to unexpected situations.

This sign indicates a merge ahead. It warns that two lanes of traffic moving in the same direction are about to become one.

When driving near heavy trucks, other drivers and highway users must make allowances for the increased stopping distance required by the large vehicles. Drivers of smaller vehicles should remain in locations where they can be seen by the driver of the large vehicle and where their view of traffic is not blocked by the vehicle.

Warning signs, which tell you about conditions on or near the road ahead, are usually diamond-shaped with black symbols or words on a yellow background.

Warning signs are normally diamond-shaped and yellow, although orange warning signs are used in work areas. Such signs warn that you are approaching a hazardous location or an area where special rules apply.

When merging into traffic, you should signal and enter at the same speed that traffic is moving. Always yield to other traffic when entering a roadway.

Be prepared to reduce your speed and use caution when directed to do so by a sign, crossing guard, or law enforcement officer. Always drive with extra caution in a school zone.

The minimum age to acquire an instruction permit is 15 years old. This permit allows a young person to learn to drive with the supervision of a licensed adult. The fee to obtain this permit is $3.50. Application test fees are not included.

Drivers must yield to pedestrians when they are crossing at any intersection without a traffic light, whether or not there is a crosswalk.

For drivers age 21 or older, it is illegal to operate a motor vehicle with a blood alcohol concentration (BAC) of 0.08 percent or higher. Driving while under the influence of alcohol is not only illegal, but dangerous.
