Colorado CAR DMV Practice Test 9

The average person’s body will process about one alcoholic drink in one hour. However, many factors play a part in determining how impaired a person will become when consuming alcohol, including the amount of alcohol consumed, how fast it is consumed, and a person’s body weight, food intake, and general health.

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.

After stopping at an intersection, take the extra time to check for crossing traffic and bicyclists before moving. It is recommended that you look left, right, and left again before entering an intersection.

Emotions can have a great effect on your driving ability. You may not be able to drive well if you are overly worried, excited, afraid, angry, or sad. Stress can lessen your concentration on the task of driving. It is better to wait to drive than to risk driving while you are emotionally unstable.

If you experience a tire blowout, take your foot off the gas pedal and do not immediately apply the brakes. Gradually slow down before gently applying the brakes and pulling off the side of the road.

For drivers age 21 or older, it is illegal to operate a motor vehicle with a blood alcohol concentration (BAC) of 0.08 percent or higher. Driving while under the influence of alcohol is not only illegal, but dangerous.

High speeds greatly increase stopping distances and severity of crashes. The faster you drive, the greater the impact or striking power of your vehicle, should you be involved in a collision.

Crashes often happen because one driver does something that other road users are not expecting. You should communicate with other motorists, bicyclists, and pedestrians by doing things like signaling when slowing down, stopping, or changing direction. Use your emergency signals or horn when appropriate.

Traffic signals are placed at intersections to keep traffic moving and to help prevent crashes. Drivers, pedestrians, and cyclists must obey these signals, except in instances when an officer is directing traffic.

The larger the vehicle, the larger the blind spots. Large trucks and SUVs have spots close to their rears that cannot be seen in their side or rearview mirrors.

In general, vehicles at a four-way stop should proceed in the order that they arrive. However, if two vehicles arrive to the intersection at the same time, the vehicle on the left must yield the right-of-way to the vehicle on the right.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to potential traffic merging from the right. Drivers should prepare to allow the traffic to merge safely.

A flashing red light means the same thing as a stop sign. If you encounter a flashing red light, you should come to a complete stop, yield to appropriate traffic and pedestrians, and only proceed when it is safe to do so.

When turning onto a street with more than one lane moving in the direction that you are traveling, turn into the lane that is closest to your previous lane. Do not change lanes when turning.

This sign indicates that there is an intersection ahead. A road joins from the right.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign warns drivers that there is an upcoming sharp turn and that they should lower their speed accordingly.

Due to limited visibility, driving in the evening, at dusk, at night, and just prior to sunrise is normally more hazardous than driving during daylight hours. Colorado law requires you to use your headlights when driving between sunset and sunrise and at any other time when visibility is less than 1,000 feet.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign tells drivers to be cautious when driving under conditions that may cause the roadway to become wet and slippery.

Signal, check your mirrors, and check your blind spot before changing lanes or passing on an interstate. Only stop on the shoulder of the interstate in the case of an emergency and change lanes as infrequently as possible. Cruise control should not be used in heavy traffic or under poor weather conditions.

This sign indicates that right turns are prohibited. Do not make a right turn at an intersection where this sign is posted.

Some highways reserve the left lane for vehicles with two or more occupants. These High Occupancy Vehicle (HOV) lanes are indicated by signs and diamond pavement symbols and are separated by a striped buffer zone.

If you are being tailgated by another driver and there is a right lane, move over to the right. If there is no right lane, wait until the road ahead is clear and then reduce your speed slowly. This will encourage the tailgater to drive around you. Never slow down abruptly as this will only increase the risk of your vehicle being hit from behind.

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.

If another driver is threatening you or intentionally driving dangerously around you, remain calm and try to put as much distance between the two of you as possible. Slow down and let them pass. Do not make eye contact and do not make obscene gestures.

This is a "Keep right" sign. It indicates that a traffic island, median, or barrier is ahead and that drivers must keep to the right of it.
