Curves — New Hampshire Permit Test
Curves on the New Hampshire permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A driver should always reduce speed before entering a curve, to a speed that allows slight and constant acceleration through it.
Braking in a curve unsettles the car when the tires are already working hardest, so the slowing has to happen first.
Always reduce speed prior to entering the curve to a safe speed
Hard braking after entry to a curve could cause the vehicle tires to lose traction.
The tires are already spending their grip on turning, and asking them to stop as well is more than they have.
Hard braking after entry to a curve could cause the vehicle tires to lose traction.
A driver should reduce speed more in a curve when traction is poor, when following other vehicles, or when the end of the curve cannot be seen.
Each of these takes away room or grip, and a curve gives a driver no chance to get either back.
Reduce speed more when traction is poor, when following other vehicles or when the end of the curve cannot be seen.
On the test
When should a driver reduce speed for a curve?
Before entering the curve. Braking in a curve unsettles the car when the tires are already working hardest, so the slowing has to happen first. New Hampshire Driver's Manual, p.17: “Always reduce speed prior to entering the curve to a safe speed”
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.
