Brake failure — South Carolina Permit Test
Brake 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
Do not drive if the brake warning light is on.
The light means the brakes are not working properly, and the next hard stop could be the one that fails.
A brake warning light will tell you if your brakes are not working properly. Do not drive if you see this warning light.
If your brakes stop working while driving, use the parking brake, applying it slowly so the rear wheels do not lock.
Yanking the parking brake locks the rear wheels and sends the car into a skid on top of the brake failure.
Use the parking brake. Pull on the parking brake handle in the center console or push the parking brake foot pedal slowly so you will not lock the rear wheels and cause a skid.
If the parking brake also fails, turn off the engine and look for a safe place to slow to a stop off the roadway.
With no brakes at all, cutting the engine removes the power pushing the car forward while you find somewhere to coast to a stop.
If the parking brake does not work, turn off the engine and look for a safe place to slow to a stop.
On the test
The brake warning light on your dashboard is on. What should you do?
Do not drive the vehicle. The light means the brakes are not working properly, and the next hard stop could be the one that fails. South Carolina Driver's Manual, p.106: “A brake warning light will tell you if your brakes are not working properly. Do not drive if you see this warning light.”
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.
