Missouri CAR DMV Practice Test 22

When you hear the siren of an emergency vehicle, you must pull over to the curb or side of the road and stop.

When approaching an intersection with a solid yellow traffic light, slow to a stop before entering the intersection, if it is safe to do so. If you can't stop safely, drive carefully through the intersection.

Alcohol reduces your reaction time, reduces your ability to see clearly, changes your judgment of speed and distances, reduces your ability to recover from the glare of headlights, and often reduces your inhibitions and makes you more likely to take risks.

This sign means that a traffic signal is ahead. You should slow down and be prepared to stop.

This sign warns that pavement is slippery when wet. In wet conditions, you should reduce your speed, avoid braking or changing direction suddenly, and increase the distance between your vehicle and the one ahead.

The amount of space you need to cross traffic depends on the road conditions, weather conditions, and oncoming traffic.

Distractions cause drivers to react more slowly to traffic and hazards on the roadway. Distracted driving is never safe.

If you miss your turn or exit, do not back up or try to turn around on the highway. Go to the next exit and safely turn around.

Unless a posted sign indicates otherwise, a traffic signal displaying a red arrow means that drivers must come to a full stop and remain stopped until a green light or green arrow appears.

Always signal for an appropriate amount of time before making a lane change or exiting a freeway. Before you make any move to the right or left, quickly turn your head and look over your shoulder to see if your blind spot is clear.

When preparing to drive, you should first adjust your seat to ensure that you are in a comfortable position and can see the road clearly. Adjust your mirrors and steering wheel to be effective when your seat is fully adjusted.

You must stop at a railroad crossing when directed to do so by a flagger or stop sign. Stop when flashing red signals and gates are present and operating.

Slow down and be prepared to stop whenever you see pedestrians walking on or crossing the roadway. Be particularly careful where children are present. Always yield the right-of-way to a pedestrian crossing in a crosswalk.

The faster you drive on a wet roadway, the less effective your tires will be at wiping the water from the road. If your speed becomes excessive enough, your tires will lose their grip on the road entirely and you will begin to hydroplane (that is, to slide down the road on a film of water).

When passing a bicyclist, slow down and give them as much space as you can. Bicyclists have much less protection than drivers of motor vehicles and they should not be crowded. Passing a bicycle too quickly can shift the bicyclist off-course.

To avoid becoming fatigued while taking a long trip, stop every two hours for a short break. If you become drowsy, pull off the road and park in a safe place to take a nap, or find a room to stay for the night.

A large truck has large blind spots to the front, sides, and rear of the vehicle. Avoid lingering in these areas. Because of their larger size and weight, trucks require more room to maneuver and stop than passenger vehicles.

If your vehicle breaks down on the highway, you should signal before carefully exiting the roadway and turning on your hazard flashers. Get as far off the road as possible and park in a location where other drivers can easily see you. Lift your hood to let other drivers know your vehicle is disabled.

As a general rule, broken traffic lines may be crossed but solid lines may not. Solid yellow lines may be crossed only when the driver is making a turn.

Look over your shoulder to check your blind spot every time you want to change your vehicle's position. If you are turning, changing lanes, or pulling toward or away from a curb, you should check your blind spots.

A flashing red traffic light has the same meaning as a stop sign. You must stop, yield the right-of-way, and go once it is safe.

If there are two railroad tracks next to each other, watch for a second approaching train after one train passes. Do not begin to cross the tracks until you’re sure no train is approaching from either direction on either track.

You may not be able to drive well if you are worried, excited, crying, angry, or depressed. Emotions can distract you from your driving because your mind is focused on something else. Take time to calm down and get focused before driving.

Curve and turn warning signs often have attached advisory speed signs that show a recommended driving speed for drivers in the curves and turns. Although a driver may feel comfortable driving at a higher speed in fair weather, they should never do so under rainy, snowy, or icy conditions.

Construction, maintenance, and emergency operations signs are generally orange with black symbols.
