Missouri CAR DMV Practice Test 11

To check your blind spot before changing lanes, you should look over your shoulder in the direction that you plan to move.

Because of their size, trucks need longer distances to stop than smaller vehicles do.

When driving on a two-lane roadway or undivided highway, you must yield to an emergency vehicle using its lights and/or siren, regardless of the direction from which it is approaching. Immediately drive as near as possible to the right side of the road and stop, taking care not to stop within an intersection.

When the road is wet or slippery, when you cannot see well, or when anything else makes conditions less than perfect, drive below the posted speed limit. Even if you are driving within the posted speed limit, you can still be ticketed for driving too fast for conditions.

When the driver behind you wants to pass, you should slow down so that there is enough room in front of your vehicle for the other driver to complete their pass. This will allow them to complete the passing maneuver in less time and more easily.

This sign indicates that you must keep to the right of the upcoming divider.

Flashing red lights are used at dangerous intersections. Treat them like stop signs.

If your vehicle begins to skid, remain calm. Steer in the direction that you want to go and try not to overcorrect.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This sign indicates that drivers are approaching a steep hill and should prepare to adjust their speeds to continue to drive safely.

You must yield to any transit vehicle that is signaling to pull back onto the main roadway after it has stopped to load or unload passengers. Change lanes, slow down, or stop to allow the bus safe re-entry into traffic.

Blind spots are areas that a driver cannot see without moving their head. They can be located to the sides of and behind a vehicle.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to an upcoming curve in the road.

When you back up a vehicle, look through your back window for pedestrians and other obstacles. Do not rely only on your mirrors, especially when children are near. Before you back into or out of a driveway, get out of the vehicle and check behind your vehicle.

Before changing lanes, you should look in your rearview and side mirrors to make sure no one is trying to pass you. You should also look over your shoulder to make sure that no one is in your blind spot.

You must stop when approaching a school bus that is displaying flashing red lights while stopped to pick up or drop off children. On a two-lane road, traffic moving in both directions must stop and remain stopped as long as the red lights near the top of the bus are flashing and/or the stop arm on the left side of the bus is extended.

If a driver's left arm and hand are extended upward, they are indicating that they intend to turn right. Adjust your driving accordingly if following a driver who is using this hand signal.

You should pass a bicyclist the same way you would pass any other vehicle, but not so fast or close to them that you throw debris in their face or blow them around with the draft of air from your vehicle. Allow at least 3 feet of space between your side mirror and the bicyclist, or at least 5 feet on higher speed roads or when there is a group of bicyclists. Honking unnecessarily may startle riders and make them more likely to crash.

If a steady yellow light appears when you are already within an intersection, you should continue through the intersection carefully.

To prevent hydroplaning, you should ensure that the tires on your vehicle have good tread depth and are inflated to the proper pressure. Reduce the speed of your vehicle when driving in the rain. Hydroplaning occurs most frequently at higher speeds.

The only method that effectively reduces your BAC is to not drink alcohol for a period of time. Coffee, exercise, and cold showers cannot reduce your BAC or change the effects of alcohol. They can help you remain awake, but they cannot change your BAC or make you sober.

Do not use your high beam headlights when approaching or following another vehicle at night. Switch to the low beam setting to ensure the safety of everyone on the road.

It is estimated that drivers make 200 decisions for every mile traveled, making it vital that drivers focus their full attention on the task of driving. Performing any additional task can create a dangerous distraction.

A steady yellow arrow indicates that a red arrow is about to appear. Stop unless you are already within the intersection.

Tractor-trailers take longer distances to stop than smaller cars traveling at the same speed. A fully loaded tractor-trailer may take almost 400 feet to come to a complete stop when driving at 55 mph.

A steady red traffic light indicates that drivers must come to a complete stop. Driving through a red light is against the law and is extremely dangerous. Drivers may turn right on a steady red light if there is no sign prohibiting a turn on red.
