Fog driving — Maine Permit Test
Fog driving on the Maine permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Maine's manual says the best rule in foggy conditions is to avoid driving.
In thick fog no driving skill makes up for not seeing the car stopped ahead.
The best rule during foggy conditions is to avoid driving.
If you must drive in fog, reduce your speed and be prepared to stop within the limits of your vision, even if that is only a few feet.
A driver who goes faster than they can see will reach a stopped car before they see it.
Reduce your speed and always be prepared to stop your vehicle within the limits of your vision, even if those limits are not more than a few feet.
In fog, look for road edge markings to help guide you.
With the lane ahead hidden, the edge line beside your car is the one thing that shows where the road goes.
Look for road edge markings to help guide you.
If fog becomes so thick you can barely see, pull off the road and stop with your emergency flashers on, and wait for visibility to improve.
Creeping along at 5 or 10 mph in thick fog leaves you in the lane where a faster car can hit you from behind.
If the fog becomes so thick that you can barely see, pull off the road and stop, using your emergency flashers.
On the test
What does the manual call the best rule during foggy conditions?
Avoid driving in it. In thick fog no driving skill makes up for not seeing the car stopped ahead. Maine Driver’s License Manual, p.117: “The best rule during foggy conditions is to avoid driving.”
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.
