South Carolina CAR DMV Practice Test 24

Always be prepared to yield to any oncoming trains before crossing railroad tracks, particularly if there are no lights or gates controlling the crossing. Never start to cross the tracks until there is room for your entire vehicle on the other side of the tracks. Due to the risk of a vehicle stalling, it is not wise to shift gears when crossing railroad tracks.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign warns drivers that they are approaching a T intersection and should prepare to turn either right or left.

Motorcycles are smaller and harder to see than cars. Because of their size, they are easily hidden in a car’s blind spot. It may be difficult to judge your distance to a motorcycle and difficult to tell how fast a motorcycle is moving, so always be alert and extra cautious when near a motorcyclist.

SCDMV must be informed about any change to your name or address within 10 days of the change.

It is necessary to follow farther behind a large truck than you would if following a passenger vehicle because trucks have larger blind spots.

You should use your low beam headlights when driving in fog. High beams will reflect back at the driver and lower visibility.

Arrows may be used to indicate which lanes should be used for specific purposes, such as driving straight or making a turn.

Never attempt to drive on a flooded road. Even if the water looks shallow, it may hide many kinds of hazards. If you encounter a flooded area, turn around and seek another route to your destination.

On narrow roads, you must allow vehicles traveling in the opposite direction at least one-half of the main-traveled portion of the road. Both vehicles must have adequate space in order for the drivers to safely pass one another.

Bicycles on a roadway are considered to be vehicles and should be treated as such. A loud blast of your horn could startle a cyclist and cause an accident, so your horn should be used lightly only to get a cyclist's attention. Before passing a cyclist in a narrow traffic lane, wait until the traffic is clear in the opposite lane and then change lanes to pass the cyclist; do not attempt to squeeze past them.

You should always signal when turning, changing lanes, slowing down, or stopping so that other drivers, motorcyclists, bicyclists, and pedestrians will know your intentions.

White lines are used to separate traffic moving in the same direction. Solid lines indicate that drivers are not permitted to pass.

Legal medications, both prescription and over-the-counter, can potentially impair your ability to drive. Always consult with your doctor or pharmacist if you have questions about how a particular drug or drug combination will affect your ability to drive. You should particularly make a point of talking with your doctor if they give you a prescription for a tranquilizer or sedative.

A regulatory sign displaying a red circle with a red slash through the middle indicates that a specific action is prohibited. Right turns are not permitted where this sign is posted.

Large trucks and buses have large blind spots to the sides, the rear, and the front. These areas are referred to as "No zones." Drivers of smaller vehicles should avoid lingering in these areas because they will be invisible to the truck driver and may also restrict the truck driver's ability to stop or maneuver safely.

To complete a turn safely, you should activate your turn signal three to four seconds before your turn.

To make a three-point turn, stop close to the right edge of the road, look over your left shoulder to check for traffic behind you, signal a left turn, then execute the turning maneuver.

This sign provides advance warning that bicycles may be present.

Large vehicles require longer distances to stop and accelerate than smaller vehicles do. Making a sudden stop in front of a large vehicle is dangerous because the other driver may not be able to stop in time to avoid a collision.

Rumble strips create noise and vibrations to warn drowsy or inattentive drivers that they are straying off of the road or are approaching a stop sign or signal.

Yellow lines are used to separate traffic moving in opposite directions. Solid lines indicate that drivers are not permitted to pass.

When there is a solid yellow line and a broken yellow line in the center of the road and the broken line is next to your lane, you may cross the lines to pass if there is no oncoming traffic.

If you are involved in an accident, you must stop your vehicle and move it from the roadway, provide aid to anyone who is injured, notify law enforcement as soon as possible (no matter who is at fault), exchange information with other drivers involved, and submit required reports to the DMV and to your insurance company.

You are required to turn on your headlights any time conditions make it necessary for you to use your windshield wipers. Use your low beams, not your high beams, when driving in inclement weather.

Yellow centerlines are used to separate traffic moving in opposite directions. Broken lines may be crossed to pass slower-moving traffic when it is safe to do so.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign tells drivers that they may encounter traffic coming from the opposite direction.

Pedestrians have the right-of-way at street crossings but must obey traffic control signals. Where a traffic signal is not present, vehicles must stop for pedestrians in a crosswalk, whether it is marked or unmarked.

Even the smallest amount of alcohol will reduce your concentration, perception, judgment and memory, and your driving skills will suffer. No one can drink and drive safely.

This sign indicates that a stop sign is ahead.

Although the right-of-way rules provide a guide to determine who should yield the right-of-way at an intersection, no one should assume they automatically have the right-of-way. The situation and circumstances at an intersection must always be considered. Drivers should yield their legal right-of-way if it can help prevent a collision.
