Sample South Carolina DMV practice questions

Try a few representative questions below. Each includes the correct answer and a short explanation — the same style you'll see in the full practice test.

1. Question 1Alcohol, Drugs, and DUI

   A police officer pulls you over and suspects you are driving under the influence. You refuse to take a breathalyzer test. What is the most likely immediate consequence under most state 'implied consent' laws?

   • A.You will be required to perform field sobriety tests.
   • B.The officer will issue a warning and let you go.
   • C.Your driver's license will be suspended for a period of time.(Correct)
   • D.You will be arrested and charged with DUI immediately.

   Explanation

   Refusing a chemical test (like a breathalyzer) when suspected of DUI typically results in an automatic driver's license suspension under implied consent laws. This suspension is separate from any potential DUI conviction. Arrest and charges may still occur, but license suspension is the direct consequence of refusal. Performing field sobriety tests is often requested before arrest, not as a consequence of refusal.

2. Question 2Sharing the Road

   You are driving a passenger vehicle and approaching a large, multi-unit truck in the right lane. The truck is signaling to change lanes to the left. What is the most important consideration regarding the truck's 'no-zones'?

   • A.You should honk your horn to alert the truck driver of your presence.
   • B.The truck driver may not be able to see you if you are beside them in their blind spots.(Correct)
   • C.You can safely accelerate to pass the truck while it is signaling.
   • D.The truck driver is required to yield to you if you are already in the passing lane.

   Explanation

   Large trucks have significant blind spots, known as 'no-zones,' particularly on the sides and directly behind them. If you are in one of these no-zones, the truck driver may not see you, making a lane change by the truck dangerous for you. Drivers are not required to yield to vehicles signaling a lane change, and honking may startle the driver. Accelerating while the truck is signaling to change lanes is extremely risky.

3. Question 3Traffic Signs and Signals

   You are approaching an intersection and observe a traffic signal that is displaying a steady red light. Simultaneously, a police officer is present and directing traffic, waving you through the intersection. What should you do?

   • A.Proceed with caution only after ensuring no other vehicles are entering the intersection.
   • B.Honk your horn to get the officer's attention and confirm their instructions.
   • C.Stop and wait for the traffic signal to turn green, regardless of the officer's presence.
   • D.Obey the police officer's directions, even if they contradict the traffic signal.(Correct)

   Explanation

   Traffic signals and signs are regulatory, but the directions of a police officer or fire fighter directing traffic supersede any traffic control device. Always obey the lawful directions of law enforcement. Stopping for a green signal when directed to proceed is unnecessary and may cause confusion, while proceeding without confirming the officer's intent or honking is unsafe and disrespectful.
