Oregon CAR DMV Practice Test 13

This sign warns that the road is slippery when wet.

One situation where it is appropriate to use your horn is if you lose control of your vehicle. In this case, sound your horn to alert other drivers.

If you are being tailgated by another driver and there is a right lane, move over to the right. If there is no right lane, wait until the road ahead is clear and then reduce your speed slowly. This will encourage the tailgater to drive around you. Never slow down abruptly as this will only increase the risk of your vehicle being hit from behind.

Work zones are often stationary, but they may also be present in the form of moving vehicles striping lines, mowing, or removing snow. Work zones are marked by orange signs with black lettering or symbols. Slow down and pay extra attention when approaching or driving through a work zone.

Reduce your speed when roads are snow-covered or icy. Doing this and increasing your following distance are the most important techniques for avoiding crashes under snowy or icy conditions.

You must stop for pedestrians crossing the road at any marked or unmarked crosswalk. Yield the right-of-way and proceed when the crosswalk is clear.

Alcohol is a depressant drug that slows the activity of the brain and reduces the skills that you need for safe driving. Drinking alcohol results in slowed reaction time and impaired judgment.

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.

When turning left, drivers must yield the right-of-way to oncoming traffic. Drivers must also always yield the right-of-way to pedestrians, bicyclists, and other drivers who are already in the intersection.

Use the entrance ramp to accelerate to the speed of freeway traffic and yield to traffic already using the freeway. Before entering traffic, use your mirrors and check your blind spots to verify that you have room to safely merge.

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.

Construction and maintenance signs are orange-colored and are used to notify drivers of unusual or potentially dangerous conditions in or near work areas. This sign warns drivers that they are approaching a construction zone and that they should prepare to lower their speed and drive with extraordinary caution.

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.

A steady downward green arrow over a traffic lane means you may use the lane indicated.

Motorcycles are smaller and harder to see than cars. Because of their size, they are easily hidden in a car’s blind spot. It may be difficult to judge your distance to a motorcycle and difficult to tell how fast a motorcycle is moving, so always be alert and extra cautious when near a motorcyclist.

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

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

You should never drive around lowered crossing gates. Always look both ways before turning across train tracks and always obey signs and traffic signals. Trains share the road with motor vehicles and bicyclists.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign tells drivers that they may encounter traffic coming from the opposite direction.

Octagonal signs are always stop signs. Come to a complete stop when approaching a red, eight-sided sign.

At night, your field of vision is reduced. To make sure you are able to react to hazards on the roadway, always use appropriate headlights. Drive slowly enough that you are able to stop within the distance that you can see ahead.

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.

When turning, you should reduce to a speed that allows you to maintain control of your vehicle, stay in your lane, and react to unexpected situations.

This sign indicates that a divided highway begins ahead. The road will split into two one-way roadways separated by a median or divider. You must keep to the right.

Your tires become less effective at clearing water from the road as you increase your speed. If you drive too fast, they may lose their grip entirely, leaving the vehicle sliding on a film of water. This is known as "hydroplaning."

Giving false information when applying for a driver license or identification card is punishable by a one-year suspension or cancellation. In addition, submitting a false application is a class A misdemeanor, which is punishable by fines and/or imprisonment.

Alcohol is a depressant that negatively affects judgment, vision, concentration, understanding of reality, and reaction time. It is never safe to consume alcohol in any amount before getting behind the wheel of a car.

As speed increases, the chance of a fatality increases. If you are moving faster than 80 miles per hour, you have almost no chance of living through a crash. Driving more slowly than other traffic can also be dangerous because other motorists may become impatient and make dangerous moves to pass you.

The exhaust system helps remove toxic gases, reduce the noise, and cool the hot gases coming from a running engine. Fumes from a leaky exhaust system can cause death in a very short time. They can also make you drowsy while driving.

If you are involved in a crash, move your vehicle off of the road and stop, if possible. If anyone is injured, call 911 and provide appropriate help. You must report the crash to law enforcement if there is an injury, a death, and/or more than $1,000 in property damage (or more than $200 worth of damage made to non-vehicle government property, such as signs or guardrails).

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.

When you leave your vehicle unattended, you must stop the engine, lock the ignition, remove the key from the ignition, and set the parking brake.

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.”

This sign provides advance warning that bicycles may be present.

When parking on an incline where there is a curb, you should turn your wheels sharply to the left, away from the curb. This way, if your brakes fail, your vehicle will not roll into traffic.
