SC DMV Special Driving Conditions

Question 1

What should you do to increase safety when driving in heavy rain in South Carolina?

Accepted Answer

Reduce speed, increase following distance, and turn on headlights

Answer

Rain reduces visibility and traction, requiring slower speeds, greater following distance, and headlights so others can see you.

Question 2

In South Carolina, when is black ice most likely to form?

Accepted Answer

On bridges and overpasses in near-freezing temperatures

Answer

Black ice forms most readily on bridges and overpasses because these surfaces freeze faster than ground-level roads, often at near-freezing temps.

Question 3

When driving through a flooded road in South Carolina, what is the safest action?

Accepted Answer

Turn around — never drive through flood water

Answer

Just 6 inches of moving water can knock a person down, and 12 inches can carry away a small vehicle; the SC motto is 'Turn Around, Don't Drown.'

Question 4

What is the safest way to drive through dense fog in South Carolina?

Accepted Answer

Use low-beam headlights, reduce speed, and increase following distance

Answer

Low beams illuminate the road ahead without reflecting back into your eyes; high beams scatter in fog and reduce visibility.

Question 5

When driving at night in South Carolina, you should be able to stop within:

Accepted Answer

The distance illuminated by your headlights

Answer

You should always drive at a speed that allows you to stop within the range of your headlights — known as driving within your sight distance.
