Stopping distance — Alabama Permit Test
Stopping distance on the Alabama permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Stopping distance depends on many factors, including the driver's mental and physical reaction time, the pavement, the tires, the vehicle's design, the brakes, and the wind.
No chart can promise how far you will need, so leave more room than you think when anything is less than ideal.
Type and condition of the pavement.
At 25 mph, the manual's chart gives 27 feet of thinking distance and 34.7 feet of braking distance, a total of 61.7 feet.
Even at a low speed you travel a car length or more before your foot reaches the brake.
25 27ft 34.7ft 61.7ft
Large, wide tires may help stop quicker on smooth dry surfaces but will skid or hydroplane more easily on slippery or wet ones; check your owner's manual or a dealer for the right tire size.
The best tire for a dry road is not the best for a wet one, and the right size balances the two.
The proper size tire for your vehicle is important; large, wide tires may help stop quicker on smooth, dry surfaces, but will skid or hydroplane easier on slippery or wet surfaces.
On the test
Which of these affects how far it takes to stop your car?
The condition of the pavement. No chart can promise how far you will need, so leave more room than you think when anything is less than ideal. Alabama Driver Manual, p.36: “Type and condition of the pavement.”
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.
