Missouri CAR DMV Practice Test 6

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign indicates that parking is not permitted.

"Highway hypnosis” happens when you stare straight ahead at the roadway for long periods of time and stop actively scanning ahead, behind, and around your vehicle. This can lead you to zone out, making you very likely to crash into traffic slowing or stopping ahead of you.

If your vehicle goes into a skid, you should turn the steering wheel in the direction you want the vehicle to go. As soon as the vehicle begins to straighten out, turn the steering wheel back the other way.

When you see any signs indicating a nearby railroad crossing, you should slow down, look for a train, and be ready to stop. If the red warning lights are flashing or the gate is down, you must stop 15 to 50 feet before the railroad tracks. Do not try to go around the gate.

If your wheels drop off the pavement and onto a low shoulder, you should reduce your speed without braking and very carefully turn back onto the pavement. Be aware of any nearby traffic when re-entering the road.

Drinking coffee will not reduce your blood alcohol concentration (BAC). While it may help you to stay awake, it cannot change your BAC or make you sober.

As an increasing number of drivers populate the roadways, road rage becomes more prevalent. To help prevent road rage, a driver should use proper turn signals, obey posted speed limits, and allow plenty of travel time.

A speed limit is the maximum or minimum legal speed you can travel on a road under ideal conditions. You may drive more slowly than the posted speed, but it is illegal to drive any faster. You must drive more slowly where signs or signs indicate a school zone or work zone speed limit. If conditions such as road construction or bad weather make the posted speed unsafe, drive under the speed limit.

Yellow lines tell you that the traffic on the other side of the lines is moving in the opposite direction. You should never cross two solid yellow lines to pass from either direction.

Flashing red lights, lowered crossing gates, and/or bells at a railroad crossing mean that you must come to a complete stop. You must not go across the tracks until the lights and bells have stopped and the crossing gates are completely up. Do not drive around or under a gate that is moving up or down.

Your vehicle's brake lights indicate to other drivers that you are slowing down or stopping. Your brake lights should always be in working order when you are driving on any roadway.

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.

Regulatory signs are white, rectangular signs with black markings. Drivers must obey the instructions posted on all regulatory signs. Where this sign is posted, it is prohibited for drivers to pass one another.

You should slow down at the first sign of rain, snow, or sleet, all of which can create slippery road conditions. When conditions on the road are less than ideal, safety may require that you drive more slowly than the posted speed limit.

Your blood alcohol content (BAC) depends on how much alcohol you drink, how much time passes between drinks, and your weight. It is not affected by the type of alcoholic beverages you drink, your level of physical fitness, or how well you can "hold your liquor."

Construction and maintenance signs are orange-colored and are used to notify drivers of unusual or potentially dangerous conditions in or near work areas. This sign warns drivers that they are approaching a construction zone and that they should prepare to lower their speed and drive with extraordinary caution.

This one-way sign indicates that traffic flows only in the direction of the arrow.

After stopping for a school bus that has its stop arm extended and its lights flashing, watch for children walking along the side of the road. You should always drive with caution when driving near children.

At night, visibility is reduced. Take steps to make driving in the dark more safe for you and the other drivers on the road.

Crashes often happen when some drivers go faster or slower than other vehicles on the road. Always try to drive with the flow of traffic, within the posted speed limit.

If another vehicle is approaching you head-on in your lane, you should first honk your horn to attract attention. If the other driver does not move over, try to escape to the right. If you swerve left and the other driver corrects at the last instant, you will still crash. If a collision is unavoidable, brake firmly and steadily. Every mile per hour you slow down will reduce the impact.

Do not become distracted by looking at passengers, attempting to find something in your vehicle, looking at reading material, sightseeing, or daydreaming while driving. If a driver near you seems distracted, allow them extra space because the risk of an accident is increased by their inattentiveness.

When passing another vehicle on a two-lane roadway, you must return to the right side of the roadway when there is enough room between you and the vehicle you have passed.

If an approaching driver fails to dim their high beams, glance toward the right side of the road. This will keep you from being blinded by the other vehicle’s headlights and will allow you to see enough of the road to stay on course until the other vehicle has passed.

Be prepared to reduce your speed and use caution when directed to do so by a sign, flagger, or law enforcement officer. Failure to do so is illegal and is dangerous to those working in construction zones.
