Idaho CAR DMV Practice Test 22

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow and black. This sign tells drivers that a lane is ending and that they should prepare to allow traffic to merge safely.

When there is a solid yellow line and a broken yellow line in the center of the road and the broken line is next to your lane, you may cross the lines to pass if there is no oncoming traffic.

You must not drive at a speed that is faster than is reasonable and prudent. You must drive at a speed that is appropriate for the area where you are driving, the type and condition of surrounding traffic, the presence of pedestrians, the weather, the quality of the road, and light conditions. You must drive within legal speed limits.

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.

This sign warns that pavement is slippery when wet. In wet conditions, you should reduce your speed, avoid braking or changing direction suddenly, and increase the distance between your vehicle and the one ahead.

Distracted driving is extremely risky behavior that puts not only you and your passengers in danger, but also endangers pedestrians, bicyclists, and other motorists sharing the road. Focused attention on driving helps to prevent crashes.

Keeping a safe following distance will enable you to react to an upcoming problem without the need for a emergency stop, which could cause a driver behind you to crash into the back of your vehicle.

When approaching railroad tracks, you should look, listen, slow down, and be prepared to stop for trains or other vehicles that may be using the rails.

A green arrow has the same meaning as a circular green traffic light, but traffic in the indicated lane must turn in the direction shown by the arrow.

Many over-the-counter medications can affect your ability to drive safely. If you take medication, even a remedy for colds or allergies that is not prescribed, check the label for warnings about its effects. If you are unsure, ask your doctor or pharmacist about driving while on the medication.

Consuming both alcohol and another drug may enhance the effects of both. For example, taking one drink when you are also using a cold remedy could affect you as if you have had several drinks.

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.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign indicates that drivers should keep right to avoid an upcoming potential driving hazard.

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.

Anything that causes you to take your attention away from driving, take your eyes off the road, and/or take your hands off the wheel is a distraction.

You are required to use your headlights during the day when visibility is reduced to 500 feet or less. When you first turn on your headlights, be sure they are adjusted to the low beam setting. Using high beams in fog or rain will cause the light to reflect back into your eyes, lowering visibility even more.

Before turning or changing lanes, turn your head and glance over your shoulder in the direction of your move to see if your blind spot is clear. Never rely on your mirrors alone.

The slow-moving vehicle symbol is a reflective orange triangle. Expect vehicles using this emblem to be driving at speeds of 25 mph or slower.

This sign warns that the road is slippery when wet.

You must always yield to pedestrians who are in or about to enter a crosswalk. Be alert to pedestrians when driving across intersections or turning.

Warning signs are usually diamond-shaped and yellow with black lettering or symbols. They warn drivers about special situations or potential hazards ahead.

Backing requires extra caution because it is difficult for drivers to see behind their vehicles. Before entering a vehicle to back up, walk to the back of the vehicle to check for children and small objects.

When parking facing uphill on a street that has a curb, set your parking brake and turn your steering wheel away from the curb. This way, if your vehicle starts to roll, it will roll into the curb.

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.

To ensure that you will have time to react to hazards on the roadway, it is best to keep a cushion of space on all sides of your vehicle. Do not crowd vehicles to your left and right sides.

This sign prohibits U-turns. Do not make a U-turn where this sign is posted.

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.

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

This sign indicate that the right lane ends ahead.

Yield the right-of-way to any approaching emergency vehicle that is using its flashing lights or siren, regardless of its direction of travel. You must immediately drive to the right side of the road and stop until the emergency vehicle has passed. If you are within an intersection, pass through the intersection before coming to a stop on the right side of the road.

This sign warns that especially slippery conditions exist when the road is wet.

Under no circumstances may you leave the roadway to pass another vehicle. Only pass on the right where it is safe and legal to do so.

When being approached by an emergency vehicle that is sounding its siren and/or flashing its red or blue lights, you must immediately pull to the nearest curb or edge of the roadway and stop. Remain stopped until the emergency vehicle has passed.

Under Idaho law, you are considered to be driving under the influence if you are 21 years of age or older and your blood alcohol concentration (BAC) is 0.08 percent or higher. If you are driving and your BAC is lower than 0.08 percent, you may still be convicted of driving under the influence if you have consumed other intoxicating substances.

This sign indicates that right turns are prohibited.

This sign indicates that an intersection with a crossing road is ahead.

A green light tells you that you can go through the intersection. However, you must first yield the right-of-way to traffic and pedestrians who are still in the intersection.

When approaching a railroad crossing, you must stop your vehicle no closer than 15 feet from the nearest rail if an installed electric or mechanical signal is giving warning of an approaching train. Be aware of other warning signs that may indicate an oncoming train, including seeing a lowered crossing gate or hearing an oncoming train.

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."

In cold or wet weather, you should take special care on sections of road that are shaded by trees or buildings. These areas freeze more quickly than the rest of the road and are the last parts of the road to dry.
