South Dakota CAR DMV Practice Test 24

When turning left, you should slow down and activate your turn signal before making the turn. Be careful not to cut the corner short, as this may interfere with traffic.

You should never change lanes within an intersection. Before changing lanes, always look over your shoulder to check your blind spot. Be alert to other drivers moving into the same lane.

When a school bus is stopped on the road ahead with its lights flashing and its stop arm extended, you must come to a complete stop and wait to proceed until the lights have stopped flashing and the stop arm is withdrawn. Even after the bus begins to move again, do not proceed until you are sure there are no children crossing the road ahead of you.

Use your low beam headlights when driving in foggy, snowy, or rainy conditions. Light from high beam headlights will reflect back, causing glare and making it even more difficult to see ahead.

If your vehicle begins to skid, release the accelerator or brake pedal to regain vehicle balance. Steer in the direction of the skid to regain control of the vehicle.

To do your part to prevent road rage, you should follow laws, signs, signals, and pavement markings. Always signal your intention when changing lanes.

At an intersection controlled by a steady yellow light, you should bring your vehicle to a safe stop. If you are already within the intersection when the light changes from green to yellow, continue through the intersection at a safe speed.

If a road has four or more lanes with two-way traffic, drive in the right lanes unless you are passing or turning left. If you are on an interstate highway and are driving below the speed of the flow of traffic, use the right lane.

If it feels like your tires have lost contact with the surface of the road, you should ease your foot off the gas pedal and stay off the brakes. Do not try to stop or turn until your tires are gripping the road again.

Before returning to your original lane after passing, you must make sure you are not dangerously close to the vehicle you have just passed. When you can see both of the vehicle's headlights in your rearview mirror, you may have enough room to return to the lane.

Hydroplaning is caused by driving too fast on a wet road. Slow down when driving on wet pavement to prevent hydroplaning.

When you are approaching a school bus that is stopped with its stop arm extended and lights flashing, come to a complete stop. Remain stopped until the stop signal is retracted and the flashing lights are turned off.

When driving in heavy rain at speeds as low as 30 mph, your tires may lose all contact with the road and instead ride up on a layer of water above the surface of the road. This is called "hydroplaning." If your vehicle starts to hydroplane, slow down gradually and do not apply the brakes.

You must approach all railroad crossings with extreme caution and cross only when you know that no train is coming from either direction. Be aware of vehicles that must stop at all railroad crossings, such as school buses and trucks carrying hazardous materials.

When turning right, you should slow down and activate your turn signal before making the turn. Be careful not to turn too wide for your lane, as this may interfere with traffic.

Rubbernecking (the practice of slowing down to look at collisions or other out-of-the-ordinary things) contributes to traffic congestion and should be avoided.

Your suspension helps you control your vehicle and provides a comfortable ride over varying road surfaces. If your vehicle bounces a lot after driving over a bump, or is generally hard to control, you may need new suspension parts.

Work zones on highways have become increasingly dangerous places for both workers and drivers. When approaching a work zone, watch for materials such as cones, barrels, signs, large vehicles, and workers in brightly colored vests to warn you and direct you.

If you experience a sudden tire blowout, do not panic. Grasp the steering wheel firmly and take your foot off the accelerator to allow the vehicle to roll to a stop. Lightly apply the breaks when it is safe to do so. Do not move to the shoulder of the road until the car has slowed considerably.

If your wheels drop off the roadway or pavement edge, do not attempt to turn back onto the roadway immediately. Instead, reduce your speed, check traffic, and gradually turn back onto the roadway when it is safe to do so.

Warning signs are usually yellow with black markings. This sign warns that the divided highway ends ahead. Prepare to change lanes or shift lane position.

Even if your vehicle is properly equipped with mirrors, there are blind spots that cannot be seen by using the mirrors. Before changing lanes, look over your shoulder to check these areas.

Solid yellow lines on two-lane roads indicate zones where passing is prohibited. If a solid yellow line appears next to a broken yellow line, drivers in the lane nearest to the solid yellow line may not pass. In some instances, both yellow lines will be solid, indicating that it is not safe to pass from either direction.

Certain offenses committed while driving will count against a driver in South Dakota's system of suspending driver licenses. If a driver accrues 15 points or more within a 12-month period, their license will be suspended. Lengths of suspension vary based on how many offenses the driver has committed.

Any amount of alcohol acts as a depressant, slowing the function of the nervous system. It will reduce a person's alertness and ability to concentrate, increase their reaction time, and drastically reduce their coordination.
