Flooded roads — South Carolina Permit Test

Flooded roads on the South Carolina permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.

The rules

Do not drive through flooded areas; if you see a flooded roadway ahead, turn around and find another route.

Water hides dips and washed-out road, and floodwater can stall or carry away a car.

If you see a flooded roadway ahead, turn around and find another route to get to your destination.

South Carolina Driver's Manual, p.97

Just 6 inches of water will reach the bottom of most passenger cars, causing loss of control or possible stalling.

Drivers misjudge how little water it takes to lift and stall a car.

Remember, six inches of water will reach the bottom of most passenger cars, causing loss of control or possible stalling.

South Carolina Driver's Manual, p.97

2 feet of moving water can carry away most vehicles, including sport utility vehicles and pick-up trucks.

A bigger vehicle feels safe in floodwater, but it floats just the same.

Two feet of moving water can carry away most vehicles, including sport utility vehicles and pick-up trucks.

South Carolina Driver's Manual, p.97

Do not cross a flooded road even if the water looks shallow, because it can hide dips and other hazards.

Floodwater can also wash away the road beneath it, so what looks like a shallow puddle may have no road under it.

Even if the water appears shallow enough to cross, do not attempt to cross a flooded road.

South Carolina Driver's Manual, p.97

If there is no other route around a flood, go to higher ground and wait for the water to subside.

Waiting costs time, while driving in costs the car and possibly your life.

If there is no other route, proceed to higher ground and wait for the water to subside.

On the test

You see a flooded roadway ahead. What should you do?

Turn around and find another route. Water hides dips and washed-out road, and floodwater can stall or carry away a car. South Carolina Driver's Manual, p.97: “If you see a flooded roadway ahead, turn around and find another route to get to your destination.”

How this works

Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.

You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.

Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
