Power failure — South Carolina Permit Test
Power failure on the South Carolina permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
If the engine shuts off while driving, the steering wheel may be hard to turn but can still be turned.
Drivers who think the steering has locked stop trying to steer, when the car can still be guided off the road.
Be aware that the steering wheel may be difficult to turn, but it is still able to be turned.
After a power failure, do not brake hard; brake with steady pressure, slow down, and pull off the roadway.
Without the engine the brakes take more effort, and a steady push brings the car down controllably while you head for the edge.
Do not brake hard; instead, brake with steady pressure on the pedal, slow down, and then pull off the roadway.
If the engine will not restart after a power failure, raise the hood, turn on the emergency flashers, and call for help.
A raised hood and flashers tell other drivers the car is disabled, not simply parked.
and try to restart the engine; if unsuccessful, raise the hood and turn on the emergency flashers. Call for help.
On the test
Your engine shuts off while you are driving. What happens to the steering?
It is harder to turn but still turns. Drivers who think the steering has locked stop trying to steer, when the car can still be guided off the road. South Carolina Driver's Manual, p.107: “Be aware that the steering wheel may be difficult to turn, but it is still able to be turned.”
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.
