Idaho CAR DMV Practice Test 2

A wide variety of intoxicants can impair your ability to drive. These include all types of alcoholic beverages, illegal drugs, inhalants, and many legal medications (both prescription and over-the-counter).

Do not exceed the school zone speed limit during indicated times. The end of a reduced speed school zone will be indicated by an "End school zone" regulatory sign.

When roads are wet, cars take a longer distance to stop and may skid on quick turns. Do not use cruise control when driving under wet or icy conditions. Reduce your speed and drive with caution.

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.

When passing a bicyclist, slow down and give them as much space as you can. Bicyclists have much less protection than drivers of motor vehicles and they should not be crowded. Passing a bicycle too quickly can shift the bicyclist off-course.

If you drive past these signs, you are going the wrong way and are at risk of a head-on collision. You should cautiously turn around.

Some regulatory signs prohibit certain actions. These signs are rectangular and white with red and black markings. A red circle and slash on top of a black symbol indicates that the specified action is forbidden.

"No zones" are the large blind spots around trucks and other large vehicles. Drivers of smaller vehicles should avoid lingering in "No zones."

A broken yellow line alongside a solid yellow line means that passing is allowed from the lane on the side next to the broken line.

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.

Yield to pedestrians and cars that may be caught in an intersection when you have a green light. Be careful around pedestrians under every circumstance.

Yellow centerlines are used to separate traffic moving in opposite directions. Broken lines may be crossed to pass slower-moving traffic when it is safe to do so.

Many kinds of drugs can impair your ability to drive. This includes illegal drugs and legal prescription or over-the-counter medications. It can be a criminal offense to drive while impaired by any drug.

This sign indicates that the road ahead curves to the right.

At four-way stops, traffic from all four directions must stop. The first vehicle to reach the intersection should move forward first. If two vehicles reach the intersection at the same time, the driver on the left yields to the driver on the right.

You should slow down as you enter a curve and increase your speed gradually as you exit. Increasing your speed as you enter a curve will make it more difficult to control your vehicle.

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 indicates that a T intersection is ahead.

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.

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

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

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 an intersection with a crossing road is ahead.

This sign warns of two-way traffic ahead.

Signal, check your mirrors, and check your blind spot before changing lanes or passing on an interstate. Only stop on the shoulder of the interstate in the case of an emergency and change lanes as infrequently as possible. Cruise control should not be used in heavy traffic or under poor weather conditions.

A truck or bus has blind spots on each side, in the rear, and in the front. An automobile cannot be seen in these blind spots. These blind spots are referred to as the “No zone.”

White lines separate lanes of traffic that are moving in the same direction. Dashed white lines may be crossed to pass or change lanes, if it is safe to do so.

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.

Before changing lanes, you should always verify that there are no other vehicles in the lane you want to enter by checking your mirrors and looking over your shoulder in the direction you plan to move. You should signal every time you change lanes.

If you are following another vehicle at a railroad crossing, check to make sure you have enough room to get all the way across before you drive onto the tracks. You should never try to pass another vehicle as you approach or cross a railroad crossing. Always check for trains before crossing any railroad tracks.

Arrows may be used to indicate which lanes should be used for specific purposes, such as driving straight or making a turn.

On narrow roads, you must allow vehicles traveling in the opposite direction at least one-half of the main-traveled portion of the road. Both vehicles must have adequate space in order for the drivers to safely pass one another.

If your vehicle goes into a skid, you should turn the steering wheel in the direction you want the vehicle to go. As soon as the vehicle begins to straighten out, turn the steering wheel back the other way.

In snowy weather, keep your windshield and mirrors clear. Increase your following distance when driving in wet and cold weather because a slippery road surface will increase the distance needed for your vehicle to stop.

If you are involved in an accident, you must stop at or near the scene. Move your vehicle out of the way of traffic, if possible. Do not stand or walk in traffic lanes as you could be struck by another vehicle. Turn off the ignitions of wrecked vehicles.

This sign indicates that the right lane on a multilane roadway ends ahead. Traffic in the right lane must merge left.

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

When the road is wet or slippery, when you cannot see well, or when anything else makes conditions less than perfect, drive below the posted speed limit. Even if you are driving within the posted speed limit, you can still be ticketed for driving too fast for conditions.

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

Pennant-shaped warning signs like this are only used to indicate a no passing zone.
