6. If you see a flooded road ahead, turn around and find another route.

Numbers to know

3 questions from the South Carolina practice test

1. 1. When searching ahead on a South Carolina roadway, how far in front of your vehicle should you ideally look?

   1. About 3 to 5 seconds
   2. About 20 to 30 seconds
   3. About 8 to 10 seconds
   4. Only as far as the next vehicle
   Show answer

   About 20 to 30 seconds. The manual recommends looking 20 to 30 seconds ahead along your planned path. That horizon helps you notice traffic conditions, road users, and developing problems early enough to adjust speed or position. The shorter intervals in the choices “About 3 to 5 seconds” and “About 8 to 10 seconds” leave less time to make a decision, while watching only the next vehicle can hide a problem farther down the road. Use the practical cue of scanning beyond the immediate car in front, then keep your eyes moving toward the sides and rear as conditions change.

2. 2. What is the first speed adjustment a driver should make before entering a curve?

   1. Brake hard after reaching the middle of the curve
   2. Reduce speed before entering the curve
   3. Accelerate sharply before the curve begins
   4. Maintain the same speed regardless of traction
   Show answer

   Reduce speed before entering the curve. The manual recommends reducing speed before entering a curve to a safe speed that permits slight, constant acceleration through the curve. Hard braking after entry can cause the tires to lose traction, so the middle-of-curve braking choice creates the very risk the guidance warns about. Sharp acceleration and an unchanged speed ignore visibility, traction, and roadway conditions. A concrete driving cue is set the speed early, before the bend, then use smooth control while looking through the curve rather than waiting until the vehicle is already turning.

3. 3. How should a driver respond when approaching a flooded roadway or barricade blocking one?

   1. Stop in the water and wait for traffic
   2. Drive through if the water appears shallow
   3. Turn around and find another route
   4. Follow the vehicle ahead through the flooded area
   Show answer

   Turn around and find another route. A flooded roadway or a barricade blocking one calls for finding another route to the destination. Apparent shallowness can conceal dips, damaged pavement, or moving water, so entering behind another vehicle does not make the crossing safe. Stopping in floodwater adds the risk of stalling or losing control. The concrete cue is a visible flooded road: turn around before entering, choose higher or alternate ground, and never use another driver's crossing as proof that the water is safe for your vehicle.
