Oregon CAR DMV Practice Test 4

It is estimated that drivers make 200 decisions for every mile traveled, making it vital that drivers focus their full attention on the task of driving. Performing any additional task can create a dangerous distraction.

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.

Pentagonal signs indicate that you are in a school zone. Be extra alert to children and pedestrians when driving near a school.

If a vehicle approaching you is using its high beams and fails to dim them, you should 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 well enough to stay on your course until the vehicle passes.

A flashing red traffic light has the same meaning as a stop sign. You must stop, yield the right-of-way, and go once it is safe.

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.

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.

A "No standing" sign means that you may only make a temporary stop to load or discharge passengers.

This sign indicates that there is an intersection ahead. A road joins from the right.

You must yield to other drivers when entering a street from an alley, driveway, or garage. You must also yield to pedestrians who are on an intersecting sidewalk.

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.

When you back up a vehicle, look through your back window for pedestrians and other obstacles. Do not rely only on your mirrors, especially when children are near. Before you back into or out of a driveway, get out of the vehicle and check behind your vehicle.

This sign indicates that there is a traffic signal ahead.

Never make last-minute turns. If you reach an intersection where you wish to turn but you are not in the proper lane to make the turn, drive to the next intersection and then make the turn from the proper lane.

If another vehicle is approaching you head-on in your lane, you should first honk your horn to attract attention. If the other driver does not move over, try to escape to the right. If you swerve left and the other driver corrects at the last instant, you will still crash. If a collision is unavoidable, brake firmly and steadily. Every mile per hour you slow down will reduce the impact.

When entering a freeway, use the on-ramp to accelerate to the speed of freeway traffic so you can blend in smoothly and safely. Entering traffic must yield to traffic already on the freeway.

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."

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign tells drivers to be aware of potential traffic entering from an upcoming side road.

When heavy rain reduces visibility, reduce your speed. Turn on your headlights so other drivers can see your vehicle. If the rain is so heavy that you are unable to see clearly, drive onto the shoulder and stop until the rain lets up.

When there is more than one potential hazard on the road, you should ensure that you only have to deal with one of them at a time. For example, when there is a bicyclist on the right that you want to pass and an oncoming car to the left, you should not try to squeeze between both at the same time. Instead, let the oncoming car pass, and then pass the bicyclist.

You should turn your head to check your blind spots before every lane change.

This sign indicates that the road ahead turns sharply to the right and then sharply to the left.

If a tire blows out while you are driving, hold the steering wheel tightly and keep the car headed straight down the road. Ease your foot off the gas pedal and do not apply the brakes until you have complete control. When the car is under control, brake gently and pull off the road at the nearest safe location.

Under the Implied Consent Law, by driving a vehicle in the state, you give your consent to take a breath, blood, or urine test when asked to do so by a police officer if you are arrested for driving under the influence of intoxicants (DUII). Refusing to take one of these tests when asked will result in potential legal repercussions.

When you park on a downward-facing slope, turn your wheels sharply toward the side of the road. This way, if your vehicle starts to roll downhill, it will roll away from traffic.

This sign indicates that the road ahead will turn sharply to the right and then to the left.

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

After a minor collision, move your vehicle off the traveled portion of the roadway, if possible. Do not leave the scene of an accident without identifying yourself and rendering assistance.

If you approach an emergency vehicle, tow truck, or roadside assistance vehicle that is stopped with its lights flashing, you must change lanes to allow the vehicle extra space. If there is only one lane moving in your direction, or if changing lanes would be unsafe, you must slow down to a speed below the posted speed limit and give the stationary vehicle as much room as possible. Always slow down and be prepared to stop when you approach an emergency scene.

A flashing red light means that you must stop, yield to traffic and pedestrians, and go only when it is safe. At a railroad crossing, a flashing red light indicates that a train is approaching. Yield to the train, and go only when the lights have stopped flashing and all other active warning devices deactivate.

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.

Any eight-sided sign is a stop sign. At an intersection with a stop sign, you must stop completely and check for pedestrians and cross traffic in the intersection. Wait for the intersection to clear before proceeding.

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.

Downward-facing triangular signs usually indicate that drivers should yield. Once the road is clear of traffic or pedestrians and it is safe to do so, drivers may proceed.

A yield sign means that you must slow down and yield the right-of-way to traffic in the intersection or roadway you are entering.
