Poor visibility — Vermont Permit Test
Poor visibility on the Vermont permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
When visibility is poor, as in fog, heavy rain or heavy snow, use your low beam headlights.
High beams bounce off the fog straight back at you and make the view worse, not better.
When visibility is poor, such as in fog, heavy rain, or heavy snow, use your low beam headlights.
If you cannot clearly see persons or vehicles 500 feet ahead, the law requires you to have your headlights turned on.
It is a measurable test rather than a judgment about whether it feels dark yet.
If you cannot clearly see persons or vehicles 500 feet ahead, the law requires drivers to have headlights turned on.
Strong winds and heavy snow or ice can bring trees and wires down into the roadway. Never get near or cross downed wires.
A wire on the road may still be live, and there is no way to tell from a car.
Never get near or cross downed wires.
On the test
Which headlights should a driver use in fog or heavy snow?
Low beam headlights. High beams bounce off the fog straight back at you and make the view worse, not better. 2025 Vermont Driver's Manual, p.46: “When visibility is poor, such as in fog, heavy rain, or heavy snow, use your low beam headlights.”
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.
