Idaho CAR DMV Practice Test 12

Yellow lines separate traffic moving in opposite directions. A single dashed yellow line in the center of a road indicates that vehicles traveling in both directions are permitted to pass. Drivers may only begin a pass if they will not interfere with any oncoming traffic.

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.

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.

Do not drive in someone else’s blind spot. Move forward or drop back so that the other driver can see you.

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.

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.

Traffic flow is controlled by pavement markings, traffic islands, signals, and signs. These devices inform drivers of conditions on the roadway and help guide drivers safely to their destinations. You must always obey traffic signs, signals, and pavement markings.

Wearing your seat belt is the single most effective thing you can do to reduce your risk of death or injury while driving.

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.

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.

A steady yellow light on a traffic signal indicates that a steady red light will soon appear.

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.

This sign warns of the presence of a hill ahead.

The exhaust system carries exhaust gas out of the vehicle and prevents fumes from entering into the passenger compartment. To prevent carbon monoxide poisoning, keep your exhaust system free of leaks. Replace all defective parts immediately.

Yellow lines tell you that the traffic on the other side of the lines is moving in the opposite direction. You should never cross two solid yellow lines to pass from either direction.

At night, visibility is reduced. Take steps to make driving in the dark more safe for you and the other drivers on the road.

Most warning signs are diamond-shaped and yellow with black markings. These signs warn drivers about unexpected conditions that may not be readily apparent.

Only the passage of time will allow a person to overcome the influence of alcohol.

If your vehicle’s accelerator sticks open, your vehicle will continue to maintain its speed or accelerate, even if you remove your foot from the gas pedal. Turn off the ignition, using care to move the ignition switch only far enough to stop the engine and not engage the steering wheel locking mechanism. Apply your brakes and move off the road to a safe area.

A flashing red traffic light means the same thing as a stop sign. You must come to a complete stop, yield to cross traffic and pedestrians, and then proceed when the way is clear.

This sign indicates that the road that you are on intersects with a divided highway. A divided highway is two one-way roadways separated by a median or guide rail.

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

Wet roadway surfaces can be dangerously slick, especially immediately following a rainfall. When you are driving on wet roads, your vehicle is traveling on a thin layer of oil, dirt, and water. Slow down when there is heavy rain, standing water, or slush on the road to reduce the risk of your wheels losing traction on the slick surface.

You should always be cautious when passing a bicycle because the cyclist may have to swerve into traffic to avoid an object on the road. Always be particularly careful when driving near bicyclists.

Don’t make a last-minute turn into an exit. If you pass your exit, you must go to the next one.

It is illegal to drive so slowly that you disrupt the normal flow of traffic. You may receive a citation for driving too slowly.

This triangular sign is a "Yield" sign. When you see this sign, you must slow down to check for traffic and yield the right-of-way to pedestrians and approaching cross traffic. Stop only if it is necessary to do so.

This sign warns that deer cross the roadway in the area. You should slow down, be alert, and be ready to stop.

If a green arrow is shown with a red light, you can only drive in the direction of the arrow and only if the intersection is clear.

After an accident, do not move the injured unnecessarily. Unskilled handling can make serious injuries out of minor ones. Keep the injured warm until skilled help arrives. If there is severe bleeding, attempt to stop the flow of blood with direct pressure.

A steady yellow traffic light indicates that the light will soon change to red. You should be prepared to stop for the red light, if it is safe to do so.

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.

Your chance of avoiding serious injury or death in an accident is increased if you are properly wearing your seat belt. Seat belts also help drivers maintain control of their vehicles when driving on winding or rough roads and when trying to avoid a collision.

At a steady red light, you may turn right after stopping and yielding to pedestrians and cross traffic, unless otherwise posted. Additionally, when turning left from a one-way street onto another one-way street, you may proceed from a steady red light after stopping and yielding to pedestrians and cross traffic, unless otherwise posted.

Because hydroplaning is caused by driving too quickly in wet conditions, the risk of it happening can be reduced by driving more slowly.

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.

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.

Many crashes are caused by people who try to make phone calls or text while driving. In Idaho, reading, writing, sending, or receiving text messages while driving is illegal. This law does not apply to the use of hands-free devices.

You must yield to other drivers when entering a street from an alley, driveway, or garage. You must also yield to pedestrians who are on an intersecting sidewalk.

This sign warns that the road is slippery when wet.
