Idaho CAR DMV Practice Test 11

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

This sign indicates the presence of a pedestrian crossing. Drivers should be cautious when driving where pedestrians may be present.

When passing a vehicle that has just parked parallel to the road, you should assume the driver will open the door as you approach. Use extra caution when driving near parked vehicles.

Circular traffic signs indicate upcoming railroad crossings. This sign tells drivers that they are approaching a railroad crossing and should be looking for signs of an oncoming train.

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.

Be very cautious any time you encounter an animal on the roadway. Pass the animal slowly to avoid startling or frightening it.

This sign indicates that a steep downhill grade is ahead.

To prevent hydroplaning, you should ensure that the tires on your vehicle have good tread depth and are inflated to the proper pressure. Reduce the speed of your vehicle when driving in the rain. Hydroplaning occurs most frequently at higher speeds.

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.

If you look into the headlights of an oncoming vehicle, the pupil of your eye will contract. After the oncoming vehicle has passed, there will be an interval of time during which the pupil must readjust to the less intense light. During this recovery period, you are virtually driving blind.

Most of the time, you should drive in the right or center lane of the freeway. However, when driving in the right lane while another vehicle is attempting to enter the freeway from a nearby ramp, safely merge into the next lane to allow them access. During rush hour, you should avoid driving the right lane to allow room for an increased number of drivers entering the freeway.

A flashing yellow light means that you should proceed through the intersection slowly and with caution. Scan your eyes across traffic in both directions.

If their vehicle loses traction on a slippery road, a driver with an Anti-Lock Braking System (ABS) needs to press down hard on the brake pedal, hold it, and steer out of danger. In an emergency situation, the ABS automatically pumps the brakes at a faster rate than the driver could. Removing steady pressure from the brake pedal or pumping the brakes will disengage the ABS.

You should not use cruise control on snow, in rain, in fog, or under similar hazardous conditions. Winter is the most difficult driving season and requires extra caution from drivers. It is important to consistently check your antifreeze and windshield washer fluid levels. Using snow tires can increase a vehicle's traction on the surface of slippery roads.

This sign warns of an upcoming winding road with three or more curves.

Slow down or stop at an intersection to yield right-of-way to a pedestrian who is crossing or is about to cross within a marked or unmarked crosswalk. Additionally, be alert for pedestrians who are unexpectedly crossing the street in front of you.

If an approaching driver fails to dim their high beams, glance toward the right side of the road. This will keep you from being blinded by the other vehicle’s headlights and will allow you to see enough of the road to stay on course until the other vehicle has passed.

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.

Drivers must always yield to pedestrians in the street, even if they are crossing against a red light or are otherwise being careless.

You must stop at a railroad crossing when directed to do so by a flagger or stop sign. Stop when flashing red signals and gates are present and operating.

An octagonal shape is used only for stop signs. All eight-sided signs tell drivers to come to a complete stop before proceeding.

Do not stop at an accident scene unless you are involved or emergency help has not yet arrived. Keep your attention on your driving and keep moving, watching for people who might be on or near the road. Never drive to the scene of an accident, fire, or other disaster just to look.

A solid yellow arrow has the same meaning as a yellow traffic light. When approaching a solid yellow arrow, you must reduce your speed and prepare for a red light.

An arrow painted on the pavement within a traffic lane indicates that drivers in the lane must make the movement indicated by the arrow. Drivers should follow directions given by any traffic signs or signals before proceeding in the direction indicated by the arrow.

The faster you drive on a wet roadway, the less effective your tires will be at wiping the water from the road. If your speed becomes excessive enough, your tires will lose their grip on the road entirely and you will begin to hydroplane (that is, to slide down the road on a film of water).

Crashes often occur when one driver does not see another vehicle or when a driver does something unexpected. Communicate with other drivers on the road to help prevent traffic crashes.

Drivers must always yield the right-of-way to a pedestrian when the pedestrian is a blind person who is using a white cane or guide dog.

"Reduced speed" signs inform drivers that they must reduce their speeds. If a new speed limit is posted on one of these signs, the new speed limit begins at the sign.

Lane usage for the motorcyclist is critical. Motorcycles are entitled to the same full lane width as all other vehicles.

Consuming alcohol and other drugs together can increase the impairing effects of both. For example, having one drink while you are also using a cold remedy could affect you as much as several drinks would when being consumed separately from any medications.

You must always bring your vehicle to a complete stop and yield to approaching traffic before proceeding past a stop sign. Don't feel pressured by surrounding traffic to avoid making a complete stop.

The most important thing to remember about driving in curves is that your vehicle’s inertia may make it difficult to turn. To maintain control, it is essential that you slow down before entering the curve.

Be alert to slick road conditions that may cause your vehicle to skid. Roads are dangerous at the start of a light rain when the water mixes with oil that has not yet washed away from the surface of the road, forming a greasy and slippery film. When there is moisture on the road and the temperature is below freezing, the moisture can turn to ice, causing the roadway to become slippery and dangerous.

This signs indicate that U-turns are prohibited in the location where it is posted.

Yield to all vehicles or pedestrians working on highway construction projects. Drive with special caution through a work zone where workers are present.

Drivers must be aware that large vehicles often travel at a speed slower than the posted speed limit, especially when driving on an incline, and should use caution when approaching a large vehicle from the rear. When on a hill with limited visibility, it is unlawful to pass another vehicle.

When using a freeway exit ramp, do not slow down until you move onto the exit ramp.

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 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.

If your accelerator sticks while you are driving, keep your eyes on the road. Quickly shift the vehicle into neutral and apply steady pressure on the brake pedal. Pull off the road when it is safe to do so and turn off the engine.
