Colorado CAR DMV Practice Test 21

To slow down on a slippery road, you should first take your foot off the gas pedal. If you need to slow down even more, gently apply a slow, steady pressure to your brake pedal.

This sign indicates that there is a traffic signal ahead.

Lane usage for the motorcyclist is critical. Motorcycles are entitled to the same full lane width as all other vehicles.

One strategy to avoid driving while impaired or intoxicated is to arrange for a ride home with a friend who does not drink. Drinking coffee or taking a cold shower cannot reduce your blood alcohol content or reduce the effects of alcohol. On average, it takes about an hour for the body to eliminate the alcohol from a single drink.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to an upcoming traffic signal. They should be prepared to respond to a yellow light, red light, and/or cross traffic.

Yellow lines are used in the center of the road to separate lanes of traffic moving in opposite directions.

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

Hydroplaning happens when a vehicle glides on top of a thin layer of water between its tires and the road. Tires with low air pressure or bad tread can increase the risk of hydroplaning. Speeding also increases the risk.

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.

To keep your vehicle from rolling into traffic when parked facing uphill, turn your front wheels sharply away from the curb. If you are parking uphill on a street that has no curb, turn the wheels sharply toward the edge of the road.

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

White lines separate traffic lanes traveling in the same direction. You may cross broken white lines to pass, as long as the passing lane is clear.

If a vehicle approaching you is using its high beams and fails to dim them, you should 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 well enough to stay on your course until the vehicle passes.

You must yield the right-of-way to any emergency vehicle that is using its siren or flashing lights.

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.

Never make last-minute turns. If you reach an intersection where you wish to turn but you are not in the proper lane to make the turn, drive to the next intersection and then make the turn from the proper lane.

HAWK signals are used at pedestrian crossings. If the signal changes to a solid red, drivers should come to a complete stop.

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.

Develop a routine for entering and leaving your car. Before switching on the ignition, buckle your safety belt and see that all passengers do likewise.

Railroad crossings are always dangerous. Drivers should always look and listen for trains approaching from either direction on all railroad tracks. Always follow the directions indicated by signs, signals, and flaggers. Never proceed past a railroad crossing until you are certain it is safe to do so.

"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.

You should look and listen for trains before crossing any railroad tracks. If an approaching train is near enough or going fast enough to be a danger, you cannot go across the tracks. This is true even if they have no signals or the signals are not working.

As alcohol builds up in your system, it will slow your reactions, make you feel more confident, and cause you to make more errors.

To turn left from multilane streets and highways, start from the left lane.

Use the entrance ramp to accelerate to the speed of freeway traffic and yield to traffic already using the freeway. Before entering traffic, use your mirrors and check your blind spots to verify that you have room to safely merge.
