South Carolina DMV Permit Practice Test

Not quite. The answer is buses only.

On various roadways, one or more lanes may be reserved for special vehicles. Reserved lanes are marked by signs stating that the lane is reserved for special use. "Transit" or "Bus" means that the lane is for bus use only. (Note: A bus rapid transit system including reserved bus lanes is planned for Charleston by 2025.)

Not quite. The answer is You may not turn right.

A red slash inside a red circle means "no." This regulatory sign prohibits drivers from making a right turn. This sign is located on the right side of a roadway or over a travel lane.

Not quite. The answer is Middle lanes

Smooth driving allows you to keep more distance between yourself and other drivers. It also helps save gas. Where there are three or more lanes going in one direction, the middle lanes usually offer the smoothest flow of traffic. The left lane is for drivers who want to go faster, pass, or turn left. Slower vehicles and those turning right should use the right lane.

Not quite. The answer is a flagperson (flagger) ahead.

This work zone sign indicates a flagperson (flagger) ahead. Flaggers are often located in highway or street work zones. They use red flags or STOP/SLOW paddles to guide traffic safely through these areas. Flaggers are legally authorized to direct traffic. You must follow the flagger's directions.

Not quite. The answer is A pedestrian crossing is ahead; vehicles must yield.

This figure means that a pedestrian crosswalk is ahead. Drivers must yield to pedestrians.

Not quite. The answer is Car B

Whenever two cars arrive at a four-way stop or an uncontrolled intersection (i.e., one without signs or signals) from opposite directions at about the same time, the car turning left must yield. Here, Car A must yield to Car B. At a four-way stop, each vehicle must come to a complete stop before proceeding.

Not quite. The answer is all of the above.

Not quite. The answer is Low clearance ahead

This sign indicates that this roadway's vertical clearance here is 12' 6" (twelve feet six inches). Vehicles taller than this should not proceed on this roadway. In South Carolina, trucks can normally be up to 13' 6" tall.

Not quite. The answer is move into the right lane.

If you see this sign and you are traveling slower than most traffic, move into the right lane so faster traffic can pass you on the left.

Not quite. The answer is stop if it is safe to do so.

A steady yellow traffic light indicates that the traffic light is about to turn red. If you are already in the intersection, continue moving and clear the intersection safely. If you are not already in the intersection, stop if it is safe to do so. However, don't stop suddenly and risk getting rear-ended by the vehicle behind you. If you cannot stop safely, proceed with caution through the intersection. Never speed up in an attempt to "beat the light" before it turns red.

Not quite. The answer is There is a roundabout ahead.

This sign warns drivers that there is a roundabout ahead. A roundabout is a circular intersection in which traffic circulates counterclockwise around a central island. Slow down and prepare to yield to traffic in the roundabout before you enter it.

Not quite. The answer is You must go straight.

This sign means that you must go straight. You cannot turn here.

Not quite. The answer is False

Alcohol impairs your judgment, vision, color acuity, and reaction time. Alcohol slows your ability to process information and respond to the task of driving.

Not quite. The answer is Traffic in the right lane must turn right, and traffic in the second lane should go straight or turn right.

This sign means that traffic in the right lane must turn right, and traffic in the second lane should either continue straight or turn right.

Not quite. The answer is This driver intends to slow down or stop.

This hand signal is the equivalent of the brake lights on the driver's vehicle. This driver intends to slow down or stop.

Not quite. The answer is not depend on your mirrors. Instead, turn your head to look through the rear window.

Before you back up, make sure that it is safe to do so and will not interfere with other traffic. It is a good idea to walk behind the vehicle to make sure that a child, pet, or toy is not in the way. Turn your head so you can look over your shoulder and through the rear window. Do not depend on your mirrors; they have blind spots.

Not quite. The answer is Telephone service is available ahead.

This sign is a service sign. It indicates that telephone service is available ahead.

Not quite. The answer is the time of day.

How much alcohol you drink, how fast you drink it, and how much you weigh can all affect your blood alcohol concentration (BAC). The time of day does not affect your BAC. Alcohol can affect your driving abilities at any time.

Not quite. The answer is turning the steering wheel when you turn your head to check your blind spots.

When you turn your head to check your blind spots, keep the steering wheel straight. (People have a natural tendency to turn their arms in the same direction as their head turns.)

Not quite. The answer is (a) your driving is visibly impaired

In any US state, you can be charged with driving under the influence (or whatever the equivalent term is in that state) if your driving is visibly impaired by any substance. However, there is still debate over what minimum blood tetrahydrocannabinol (THC) level should be considered evidence of driving under the influence. As of 2023, 14 states enforce zero tolerance of blood THC even for adult drivers. Five states have set numerical limits on blood THC; typically, 5 nanograms or more per milliliter of blood constitutes being under the influence. Other states have no policies on blood THC.
