Flooded roadways — New Hampshire Permit Test
Flooded roadways on the New Hampshire permit test — 2 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A driver should not drive through large bodies of standing water on a road, and should find another route instead.
There is no way to tell from the seat how deep the water is or whether the road is still under it.
Do not drive through large bodies of standing water on a road. If there is a flooded roadway, find another route to travel.
Gravel or dirt roads can reduce traction, so drivers should reduce speed, increase the following distance, and be aware the vehicle may skid when trying to stop.
Loose surface rolls under the tires, so the car behaves as though it were on ice even in dry weather.
Drivers should reduce speed, increase the following distance and be aware that the vehicle may skid when trying to stop.
On the test
What should a driver do at a flooded roadway?
Find another route to travel. There is no way to tell from the seat how deep the water is or whether the road is still under it. New Hampshire Driver's Manual, p.18: “Do not drive through large bodies of standing water on a road. If there is a flooded roadway, find another route to travel.”
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.
