South Carolina Road Sign Practice Test

How road signs are tested in South Carolina

Road sign questions are part of the South Carolina written knowledge test (30 multiple-choice questions, 24 right to pass). Know the signs well and those questions become easy points.

Signs from the South Carolina Driver's License Manual (March 2026). What every kind of sign means, by shape and color: our road sign guide.

Signs the South Carolina Driver's License Manual adds

• Traffic Signs

  Warning signs show the road ahead: a Y-intersection sign means the road splits in two; a curvy (winding) road sign means several curves in a row; a right curve sign means the road bends right. p. 6-4

• Roundabouts and Traffic Circles

  The Roundabout Ahead sign warns of a roundabout; slow down and follow roundabout rules. p. 7-7

• Slow-Moving Vehicles

  A reflective orange triangle on the back of a vehicle means it travels under 25 mph, such as farm or construction equipment. p. 10-15

• Traffic Signals

  At a red light you may turn right unless a sign prohibits it, but you must first stop before the near crosswalk and yield to pedestrians in or near the crosswalk and to other traffic using the intersection. p. 6-3

• Regulatory Signs

  The No U-Turn sign (a U-shaped arrow crossed by a red circle and slash) means you may not make a U-turn there. p. 6-9

• Traffic Signs

  A red circle with a slash over a symbol means that action is not allowed. p. 6-9

• Work Zone Signs

  Work zone signs, usually orange diamonds or rectangles with black letters or symbols, warn of workers ahead, reduced speed zones, detours, slow construction equipment and poor or changing road surfaces. p. 6-7 to 6-8

• Work Zone Signs

  In work zones a flagger with a sign or flag may tell you which way to go, to slow down or to stop, and you must follow those instructions. p. 6-8

• Route Number Signs

  The shape and color of a route number sign show the type of road (interstate, US, state, city, county or local); follow route signs on a trip to avoid getting lost. p. 6-11

• Guide Signs

  Guide signs are square or rectangular and green, brown or blue; they show intersecting roads, direct you to cities and towns, show points of interest, and help you find hospitals, service stations, restaurants and hotels. p. 6-11

  A vehicle with a disability plate or placard may use disability parking only when it is driven by or carrying the person with the disability named on the registration; you are responsible for not leaving your parked vehicle as an obstruction. p. 7-10

  A pedestrian crossing sign means slow down and yield to pedestrians in the crosswalk. p. 10-1
