Emergency braking — Louisiana Permit Test
Emergency braking on the Louisiana permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
With brakes that are not anti-lock, do not brake hard and hold, because it locks the wheels and puts the car into a skid.
Locked wheels slide instead of roll, and a sliding car cannot be steered.
If you have a manual (disc) brake system, do not brake hard and hold.
To stop quickly without anti-lock brakes, push the pedal hard, let up quickly as the car begins to skid, then push down again, pumping until stopped.
Pumping lets the wheels roll for a moment between pushes, so you keep some steering.
3. As the car begins to skid, quickly let up on the brake.
When brakes are pressed hard, an anti-lock braking system (ABS) pumps the brakes up to 30 times a second.
The system pumps far faster than any foot can, so you do not need to pump an ABS pedal yourself.
If you have an anti-lock braking system (ABS), when the brakes are pressed hard, the ABS pumps the brakes up to 30 times/sec.
ABS does not stop the car faster; it lets you steer to safety while you brake.
Drivers who think ABS shortens their stop may follow too close and still hit the car ahead.
ABS does not stop the car faster.
If the ABS light stays lit after you start your vehicle, the ABS is not working correctly.
The light should come on and then dim; if it stays on, you may not have anti-lock help in an emergency.
If the light stays lit the ABS is not working correctly.
On the test
Without anti-lock brakes, why should you not brake hard and hold in an emergency?
It locks the wheels into a skid. Locked wheels slide instead of roll, and a sliding car cannot be steered. Class D & E Driver's Guide, p.113: “If you have a manual (disc) brake system, do not brake hard and hold.”
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.
