South Carolina drivers are taught a minimum gap for following another vehicle. How much space should the blue car leave behind the red car?

Answer options
AOne car length for each 10 mph, or a 1-second gap
BOne car length for each 10 mph, or a 3-second gap Correct
COne car length for each 10 mph, or a 5-second gap
Why
South Carolina's guideline is a gap of no less than 3 seconds behind the vehicle ahead, often paired with the older rule of one car length for each 10 mph. Leave extra room when rain, fog, or ice makes stopping harder.
