Colorado CAR DMV Practice Test 10

Fog can greatly reduce your ability to see other vehicles, pedestrians, and traffic signals. When driving in fog, drive cautiously and at reduced speeds. Do not use high beam headlights. Low beams better illuminate the road and objects ahead in foggy conditions.

If you become stranded in a snowstorm, the best thing to do is stay in your car and wait for help. You are most likely to be found if you don't leave your vehicle. Additionally, it may be unsafe to walk around outside in a snowstorm.

A regulatory sign displaying a red circle with a red slash through the middle indicates that a specific action is prohibited. U-turns are not permitted where this sign is posted.

Accelerate gradually and smoothly with the top of your foot on the gas pedal and the heel of your foot on the floor. Depressing the gas pedal too quickly can cause the wheels to spin or cause your vehicle to slide, especially if the pavement is wet.

HAWK signals are used at pedestrian crossings. If the signal changes to a solid black, drivers should proceed past the crosswalk with caution.

Yield to pedestrians and cars that may be caught in an intersection when you have a green light. Be careful around pedestrians under every circumstance.

When changing lanes, you should check your vehicle's blind spots by looking over your shoulder in the direction that you want to move. Always check your mirrors and turn on your directional signal before beginning a lane change.

If you must drive in foggy conditions, you should use your low beam headlights, as well as your fog lights, if your vehicle has them. High beams direct their light upwards, where it can bounce off the fog and into your eyes, reducing visibility even more.

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.

To avoid the dangers of road rage, you should never take it personally if another driver cuts you off in traffic. Just let it go and continue driving safely.

Drivers behind a transit bus are required to yield the right-of-way to the bus if it signals to enter a traffic lane. When encountering a transit bus trying to re-enter traffic, either change lanes or slow down to allow for safe merging.

When entering a roundabout, you must yield to pedestrians, bicyclists, and vehicles that are already in the roundabout.

Your blood alcohol content (BAC) depends on how much alcohol you drink, how much time passes between drinks, and your weight. Eating before or while you drink helps slow the absorption of alcohol somewhat, but it cannot prevent intoxication or impairment if you have too much to drink.

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.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. Wherever this regulation sign is posted, U-turns are not permitted.

If your vehicle's turn signals do not work, you should use hand signals to indicate when you intend to change direction.

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

When changing lanes, it is important to check your blind spots. Do this by looking over your shoulder toward the next lane. Do not rely only on your mirrors.

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.

A green steady arrow means you may pass through the intersection in the direction that the arrow is pointing. Oncoming traffic is required to stop for turning traffic.

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.

Unless otherwise posted, the maximum speed limit on open mountain highways in Colorado is 40 mph. If a posted sign indicates otherwise, follow the speed limit on the posted sign.

Telltale signs of drunk driving include speeding, weaving, driving more slowly than the normal traffic flow, making jerking motions, and making quick and sudden stops.

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

This sign indicates that the road ahead winds with a series of turns or curves.
