Oklahoma CAR DMV Practice Test 4

You must yield to pedestrians at all times. If the pedestrians are jaywalking or crossing the street where they should not be, you must still stop for them.

If you miss your turn or exit, do not back up in the travel lane or on the shoulder. Continue to drive to the next exit or crossroad. Drivers do not expect a vehicle to be backing toward them on the roadway and doing so will likely cause a collision.

If your vehicle breaks down on the highway, you should signal before carefully exiting the roadway and turning on your hazard flashers. Get as far off the road as possible and park in a location where other drivers can easily see you. Lift your hood to let other drivers know your vehicle is disabled.

This one-way sign indicates that traffic flows only in the direction of the arrow.

This sign indicates that the overpass ahead has a low clearance. You should not proceed if your vehicle is taller than the height shown on the sign (in this case, 13 feet 6 inches).

Regulatory signs require drivers to obey an indicated instruction. Failure to comply is subject to penalty.

For drivers age 21 or older, it is illegal to operate a motor vehicle with a blood alcohol concentration (BAC) of 0.08 percent or higher. Driving while under the influence of alcohol is not only illegal, but dangerous.

When backing up, place your right arm on the back of the passenger seat and look directly through the rear window. Do not depend on your rearview or side mirrors as mirrors do not show directly behind your vehicle. Only drive in reverse at a low speed.

You must stop at a railroad crossing when directed to do so by a flagger, stop sign, or warning devices, such as gates or flashing lights. Not all railroad crossings are equipped with such devices. It is against the law to drive around lowered railroad crossing gates.

When passing, you should not return to your original lane until you can see both headlights of the passed vehicle in your rearview mirror. Always check your blind spots before moving back into your original lane.

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

When driving too quickly in wet conditions, your tires may lose all contact with the road surface. Loss of traction will cause the vehicle to ride on top of the water, which is called "hydroplaning." The best way to prevent this from happening is to drive more slowly in rainy or wet conditions than you would when driving during ideal weather conditions.

This sign warns that pavement is slippery when wet. In wet conditions, you should reduce your speed, avoid braking or changing direction suddenly, and increase the distance between your vehicle and the one ahead.

This sign indicates that there is merging traffic entering from the right.

After coming to a full stop, vehicles should proceed through a four-way stop in the order in which they arrive to the intersection. If multiple vehicles arrive at the same time, the vehicle on the left must yield the right-of-way to the vehicle on the right.

Before changing lanes, check your side and rearview mirrors for traffic approaching you from behind. Use your turn signal to let other drivers know you plan to change lanes. Check for other drivers who also may be moving into the same lane.

Upon striking an unattended vehicle, stop and try to locate the owner. If you cannot find the owner, leave a written notice containing your name, your address, and the circumstances of the accident.

This sign warns of an upcoming winding road with three or more curves.

Where this sign is posted, it is prohibited to make a right turn. It would be unsafe and unlawful to make a right turn at an intersection with this sign.

When following a motorcyclist, allow for at least a three- to four-second following distance. Motorcycles can stop quickly and following them too closely endangers your life and that of the motorcyclist. If the motorcyclist should fall, you need extra distance to avoid the rider. The chances of a fall are greatest on wet and icy roads, gravel roads, and metal surfaces such as bridges, gratings, and streetcar or railroad tracks.
