Oregon CAR DMV Practice Test 17

The distance that a vehicle needs to stop depends on the motorist's reaction time, weather and visibility conditions, the vehicle's weight, the conditions of the vehicle's brakes, the condition and type of the vehicle's tires, roadway conditions, and speed.

If a driver's left arm and hand are extended downward, they are indicating that they intend to stop. Adjust your driving accordingly if following a driver who is using this hand signal.

Railroad crossings are always dangerous. Drivers should look and listen for an approaching train coming from either direction before proceeding across the tracks. Watch for signals indicating an approaching train and never proceed until you are certain it is safe to do so.

This sign indicates that the road ahead curves to the right and then to the left. You should slow down to be able to negotiate these curves safely.

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.

To keep your vehicle from rolling into traffic when parked facing uphill, turn your front wheels sharply away from the curb. If you are parking uphill on a street that has no curb, turn the wheels sharply toward the edge of the road.

Oregon law requires safety belt use by all drivers and passengers, regardless of seating position. Properly fastened safety belts are your best defense in a collision.

Blind spots are areas that a driver cannot see without moving their head. They can be located to the sides of and behind a vehicle.

Yellow lines are used to divide traffic moving in opposite directions.

This sign indicates that there is a traffic signal at the intersection ahead.

Your horn should be used to warn other drivers or pedestrians in situations where they may not see you. For example, if you think another driver is about to hit you, you should sound your horn.

Pavement can become very slippery within the first 10 to 15 minutes of a rainstorm because the rain causes oil in the asphalt to rise to the surface of the road. This problem becomes even worse in hot weather. The heat combined with the water causes more oil to rise to the road surface.

This is a "Keep right" sign. It indicates that a traffic island, median, or barrier is ahead and that drivers must keep to the right of it.

This sign warns that the overpass ahead has a low clearance. Do not proceed if your vehicle is taller than the height indicated (in this case, 13 feet, 6 inches).

Always use the proper turn signal when changing lanes, pulling into or out of a parking space, or pulling into traffic from an alley or parking area. Communicate with other drivers on the road to help prevent accidents.

Stopping suddenly can make it difficult for drivers behind you to avoid a rear-end collision. When stopping, release the accelerator to allow your vehicle to slow. Press the brake pedal by applying steady pressure, activating your brake lights and causing the vehicle to stop smoothly.

At a solid red light, you may generally turn left or right from a two-way road onto a one-way road after stopping and yielding to all traffic and pedestrians. Watch for signs prohibiting turns on red.

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.

This sign indicates that the shoulder is lower than the road in the area ahead. If you drift off of the roadway and one wheel drops onto a low shoulder, do not slam on the brakes or steer sharply to try to get back onto the roadway. This could easily cause you to lose control of your vehicle.

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

Being fatigued while driving is similar in danger to driving under the influence of alcohol. If you begin to feel tired while driving, the best thing to do is to stop driving.

If you have been convicted of multiple traffic offenses and/or preventable traffic accidents over a certain period of time, you may be subject to the Driver Improvement Program. Among other penalties, drivers age 18 and older will receive a 30-day license suspension if they have four convictions and/or accidents in a 24-month period. Drivers under the age of 18 will receive a 90-day restriction if they have two convictions and/or accidents, and a six-month suspension if they have a third.

If the weather changes suddenly, you will need to adjust your driving to adapt. Always slow down when driving in rainy or foggy conditions. Be especially aware of vehicles behind you that may be going too fast for conditions.

When turning left at a traffic signal, you must yield the right-of-way to pedestrians and oncoming traffic.

When driving an unfamiliar vehicle, take a few minutes before driving to familiarize yourself with the location and operation of the turn signals, hazard warning signals, headlights and beam selector, windshield wipers and washers, brakes, gear selector, and horn. Any defects should be corrected before the vehicle is driven.

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.

When approaching an unmarked railroad crossing, slow down and be prepared to stop. Before you cross, be sure that no trains are approaching from either direction on any track. If you see or hear a train coming, stop at a safe distance from the nearest track and wait to proceed until after the train passes.

Each time you pass another vehicle, there is an increased chance for a collision. If you are moving faster than surrounding traffic, you will have to continue passing others. Drive with the flow of traffic, within the legal speed limit, and pass only as needed.

As a general rule, broken traffic lines may be crossed but solid lines may not. Solid yellow lines may be crossed only when the driver is making a turn.

If your vehicle's turn signals do not work, you should use hand signals to indicate when you intend to change direction.

This sign indicates that right turns are prohibited. Do not make a right turn at an intersection where this sign is posted.

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.

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.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This sign indicates that the divided highway is about to end.

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.
