Oklahoma CAR DMV Practice Test 13

Persons who are upset, angry, or otherwise distracted by their emotions should take time to cool off before driving a car. Taking out frustrations or anger while driving is exercising very poor judgment and is very dangerous to both the driver and others on the road.

Lane control signals are used when the direction of the flow of traffic in a specific lane changes throughout the day. They are used to show which lanes of traffic are open and closed, as well as to show if toll booths are open or closed. When a lane control signal contains a flashing yellow X, drivers may only use the indicated lane to complete a left turn.

Driving more slowly than the flow of traffic can be hazardous. If you are on a two-lane, two-way road and driving so slowly that traffic is backing up behind you, you are required to pull off the road and let the other vehicles pass. Only drive significantly under the speed limit when conditions require it.

When you intend to back up, always check behind your car for bikes, tricycles, and small children before you get into your car. This is an especially important practice for drivers of larger vehicles, such as vans and trucks.

You may not pass another vehicle on a hill or in a curve because you cannot see oncoming traffic and may cause a collision. Never pass another vehicle by driving onto the shoulder of a highway. Passing another vehicle by driving over a solid yellow line is prohibited.

Drivers of trucks, buses, vans, or any vehicles pulling campers or trailers may not be able to see you if you are driving directly behind them. Increase your following distance when driving behind one of these vehicles. Additionally, large vehicles can block your view of the road, so increase your following distance to look around the sides of the vehicle and see the road ahead.

Decrease your speed as you approach an intersection with a yield sign. Prepare to stop and yield the right-of-way to vehicles and pedestrians in the intersection or crossroad. You must come to a full stop at a yield sign if traffic conditions require it.

A broken yellow centerline next to your side of the road indicates that traffic may cross the centerline to pass from your side of the road.

A large truck has large blind spots to the front, sides, and rear of the vehicle. Avoid lingering in these areas. Because of their larger size and weight, trucks require more room to maneuver and stop than passenger vehicles.

You are responsible for driving with extreme caution where children are present. Slow down near schools and playgrounds and in residential areas.

This signs warns that a four-way intersection is ahead.

This sign prohibits right turns. You cannot make a right turn at an intersection where this sign is posted.

Lane control signals are used when the direction of the flow of traffic in a specific lane changes throughout the day. They are used to show which lanes of traffic are open and closed, as well as to show if toll booths are open or closed. Never drive in a lane marked with a red X.

Backing up is always dangerous because it is hard to see behind your vehicle. Use extra caution when backing up.

A broken yellow line alongside a solid yellow line means that passing is allowed from the lane on the side next to the broken line.

If your vehicle begins to skid, do not use the brakes. Braking could make the skid worse.

If a yellow panel with the message "Exit only" is on a highway sign, the lane below the sign will not continue through the interchange. Instead, the lane will go off of the roadway to form a ramp. If you are in a lane directly under an "Exit only" sign, you may change lanes to move through the interchange or you must exit the highway.

The only method that effectively reduces your BAC is to not drink alcohol for a period of time. Coffee, exercise, and cold showers cannot reduce your BAC or change the effects of alcohol. They can help you remain awake, but they cannot change your BAC or make you sober.

When making a left turn, you should always begin signaling about 100 feet before the turn. You should keep your front wheels aiming straight ahead until it is safe to start your turn. This ensures that you will not be pushed into oncoming traffic if another vehicle hits you from behind.

Your turn signals should always be used when you make any movement to the left or right. You should use your signal when pulling into traffic from a curbside parking space, moving into a new lane, or passing another vehicle.
