Idaho CAR DMV Practice Test 18

A flashing yellow light warns of a hazard. Slow down and proceed with caution.

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

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.

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

Stopping suddenly can make it difficult for drivers behind you to avoid a rear-end collision. When stopping, release the accelerator to allow your vehicle to slow. Press the brake pedal by applying steady pressure, activating your brake lights and causing the vehicle to stop smoothly.

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.

You should allow more space in front of your vehicle than usual when you are stopped on an uphill slope. If the vehicle in front of you rolls backward toward your vehicle when traffic begins to move again, it is less likely that there will be a collision.

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.

This sign warns of the presence of a crossroad ahead.

As you approach a left turn, signal your intentions three to five seconds in advance. Continually check your rearview mirror as you gradually slow down. On a multilane road, move into the left lane before reaching the intersection where you plan to turn. Yield to traffic and pedestrians and turn when your path is clear.

On a two-lane road, all traffic must stop and remain stopped as long as the red lights near the top of a school bus are flashing and/or the stop arm on the left side of the bus is extended. On a highway with two or more lanes traveling in each direction, oncoming traffic is not required to stop when meeting a school bus.

Look over your shoulder to check your blind spot every time you want to change your vehicle's position. If you are turning, changing lanes, or pulling toward or away from a curb, you should check your blind spots.

This sign indicates that a roundabout is ahead. Enter a roundabout at a low speed and yield to existing traffic.

Smoking while driving can create dangerous distractions by causing you to take your hands off the wheel and/or your eyes off the road.

This sign means that it is not safe for drivers to enter the indicated road or driveway from their current direction. If you come across one of these signs, you should immediately turn around and drive a different way.

If a traffic light at an intersection is not functioning due to a power outage, yield to other drivers in the same manner as you would when approaching a four-way stop. When it is your turn, proceed through the intersection with caution.

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.

Yellow lines are used to separate traffic moving in opposite directions. Solid lines indicate that drivers are not permitted to pass.

Driving more slowly than the flow of traffic can be hazardous. If you are on a two-lane, two-way road and driving so slowly that traffic is backing up behind you, you are required to pull off the road and let the other vehicles pass. Only drive significantly under the speed limit when conditions require it.

Warning signs advise drivers of potentially hazardous conditions. For your own safety, obey warning signs. Disregarding the information provided by a warning sign may result in an accident due to your negligence.

If you hear a siren or an air horn close by but do not know exactly where the emergency vehicle is, safely pull over to the right side of the road and stop until you are sure it is not headed toward you.

At an intersection where there is no stop sign or traffic signal, you should yield to a vehicle approaching the intersection from the right. However, always be prepared to yield to avoid a crash. Do this by taking your foot off the accelerator, covering the brake, and looking left, right, and left again.

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.

Alcohol negatively affects many skills needed for safe driving, including your reaction time and ability to see clearly. It can also harm your judgment of speed and distance, lower your inhibitions, and make you more prone to taking chances.

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.

This is a speed limit sign. It indicates the maximum legal speed that you may drive on the road where it is posted. At times of rain, snow, ice, or other less-than-ideal conditions, you may have to drive more slowly than the posted limit.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This sign indicates that there may be pedestrians crossing the road ahead.

This sign indicates a merge ahead. It warns that two lanes of traffic moving in the same direction are about to become one.

A flashing yellow traffic light at an intersection indicates that drivers must slow down, proceed with caution, and be prepared to stop.

This sign indicates that the road ahead becomes a divided highway. Keep to the right of the divider or median.

You should pass a bicyclist the same way you would pass any other vehicle, but not so fast or close to them that you throw debris in their face or blow them around with the draft of air from your vehicle. Allow at least 3 feet of space between your side mirror and the bicyclist, or at least 5 feet on higher speed roads or when there is a group of bicyclists. Honking unnecessarily may startle riders and make them more likely to crash.

Do not become distracted by looking at passengers, attempting to find something in your vehicle, looking at reading material, sightseeing, or daydreaming while driving. Continue scanning the road, checking your mirrors, and looking at the instrument panel at regular intervals. Developing these safe habits will keep you attentive as a driver.

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.

You must make a reasonable effort to find the owner of an unattended vehicle, or other piece of property, that has been damaged in a crash in which you were involved. If the owner cannot be located, leave your name, address, and license plate number in a note describing the crash.

If an emergency vehicle using its lights or siren approaches while you are driving on a one-way street, you must drive toward the nearest roadside and stop.

Parking is not allowed within 20 feet of a crosswalk, within 15 feet of a fire hydrant, or on any sidewalk. Be aware of prohibitive signs and curbs that are painted red, indicating additional parking restrictions.

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.

You should always turn from the lane that is closest to the direction you want to go. Turn into the lane closest to your previous lane.

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

If a driver's left arm and hand are extended downward, they are indicating that they intend to stop. Adjust your driving accordingly if following a driver who is using this hand signal.
