Oklahoma CAR DMV Practice Test 15

Driving too fast for conditions is a major cause of motor vehicle crashes. Being inattentive to surroundings can cause a driver to collide with other vehicles. Most rear-end collisions are caused by drivers following other vehicles too closely.

You should never pass if there is an oncoming vehicle in the passing lane, if your view is blocked by a curve or hill, at an intersection, before or on a railroad crossing or bridge, or in any other no passing zone. Unless you are on the opposite side of a multilane roadway with a median or shared center turn lane, you may not pass a stopped school bus that has its flashing red lights activated.

Drivers may not enter an intersection unless they can get through it without having to stop. You should wait until traffic ahead clears so that you are not blocking the intersection.

Watch 15 to 20 seconds ahead of your vehicle for cars braking, turning, or entering and exiting the road. This helps to prevent sudden stops and turns.

Stop before the stop line or crosswalk at any intersection that is controlled by a stop sign. If there is a stop sign but no stop line or crosswalk, stop before entering the intersection and proceed when it is safe to do so.

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.

When parking either uphill or downhill on a road that has no curb, you should turn your wheels so that the vehicle will roll away from the center of the road if the brakes fail.

Warning signs are usually yellow with black markings. This sign warns drivers that the upcoming road will curve right, followed by a curve to the left. Drivers should adjust their speed to safely continue on the road.

A reflective orange triangle on the rear of a vehicle means the vehicle is traveling at speeds slower than 25 mph. You may see this decal on construction equipment, farm vehicles, and horse-drawn wagons or carriages.

A double solid yellow line means that it is prohibited for vehicles traveling in either direction to cross the centerline to pass.

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."

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.

Low beam headlights should be used in fog, rain, and snow. The light from high beams will reflect back to the driver under these weather conditions, causing a glare that will make it difficult to see ahead.

If you are driving past an emergency vehicle parked on the right side of the road, you must vacate the lane closest to the stationary emergency vehicle. If you cannot move over safely, you must slow down.

You must yield the right-of-way to all emergency vehicles using a siren, air horn, and/or flashing red, blue, or white lights. Where possible, you must pull over to the right edge of the road. If you are in an intersection, drive through the intersection before you pull over.

All temporary signs in work zones have orange backgrounds with black writing and/or symbols.

You may not stop, stand, or park at a red-painted curb.

You must use the proper turn signal any time you pull away from a curb.

If a vehicle skids while hydroplaning, the driver should try to regain control of the vehicle. If that is not possible, the driver should release the accelerator and ride out the skid. The driver should not immediately apply the brakes.

When entering a roadway from a driveway or private road, you must yield the right-of-way to pedestrians and traffic on the roadway.
