Colorado CAR DMV Practice Test 17

A steady green light means you may drive through the intersection if the road is clear. You may also turn right or left on a steady green light unless a sign prohibits the turn. When turning, you must yield to other vehicles and pedestrians within the intersection.

Check the traffic behind you several times a minute to know if another driver is tailgating, approaching too fast, or trying to pass. If another car is following you too closely, slow down and let it pass. Most rear-end collisions are caused by vehicles following too closely.

Warning signs, which tell you about conditions on or near the road ahead, are usually diamond-shaped with black symbols or words on a yellow background.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign tells drivers to be aware of potential traffic entering from an upcoming side road.

Railroad crossing warning signs are used to warn drivers of the possibility of a train. Drivers should obey all railroad crossing warning signs and never go around barriers or disregard the warning sign.

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.

Persons who are upset, angry, or otherwise distracted by their emotions should take time to cool off before driving a car. Taking out frustrations or anger while driving is exercising very poor judgment and is very dangerous to both the driver and others on the road.

When entering a freeway, use the on-ramp to accelerate to the speed of freeway traffic so you can blend in smoothly and safely. Entering traffic must yield to traffic already on the freeway.

Your ability to stop is greatly affected by the condition of the road. You need to reduce your speed when road conditions are poor in order to maintain control of your vehicle. You will be at risk if you are driving too quickly on roads that are slippery and you need to stop.

Warning signs are normally diamond-shaped and yellow, although orange warning signs are used in work areas. Such signs warn that you are approaching a hazardous location or an area where special rules apply.

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."

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.

This sign indicates that workers may be on or very close to the roadway ahead, so you should take special care when traveling through the area.

Drowsiness can make people drive so poorly that they appear to be drunk. Opening a window, turning on the radio, or drinking coffee is not enough to make a drowsy driver alert to roadway hazards.

This sign indicates the presence of a pedestrian crossing. You should watch for people entering a crosswalk or crossing your path. Slow down and be prepared to stop.

When driving an unfamiliar vehicle, take a few minutes before driving to familiarize yourself with the location and operation of the turn signals, hazard warning signals, headlights and beam selector, windshield wipers and washers, brakes, gear selector, and horn. Any defects should be corrected before the vehicle is driven.

If you arrive to an open intersection at the same time as a vehicle to your right, you should yield the right-of-way to that vehicle. You may then proceed when it is safe to do so.

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.

Because a large vehicle, such as a truck or bus, has large blind spots to its sides and rear, avoid driving alongside such a vehicle and do not tailgate one.

Pennant-shaped signs usually indicate no passing zones. Text will also be on the sign to confirm that it is a no passing zone.

The amount of alcohol absorbed in your bloodstream is what causes you to feel the effects of drinking. This is called blood alcohol concentration (BAC). A driver with a BAC between 0.05 percent and 0.07 percent is presumed to be Driving While Ability is Impaired (DWAI).

Consuming even a small amount of alcohol will impair your vision, judgment, concentration, and coordination.

A flashing red light means that you must stop, yield to traffic and pedestrians, and go only when it is safe. At a railroad crossing, a flashing red light indicates that a train is approaching. Yield to the train, and go only when the lights have stopped flashing and all other active warning devices deactivate.

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

HAWK signals are used at pedestrian crossings. If the signal is flashing yellow, drivers should slow down and prepare to stop.
