Truck blind spots — Vermont Permit Test
Truck blind spots on the Vermont permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Large trucks have blind spots, called No-Zones, around the front, back and sides. If you cannot see the truck's side mirrors, the truck driver cannot see you.
The mirror test works both ways, and it is the only check you can make from your own seat.
Remember, if you can’t see the trucks rear (side) view mirrors then the truck driver can’t see you.
Unlike other vehicles, trucks have long blind spots directly behind them. Following too closely also cuts down your own view of traffic and raises the chance of a rear-end collision.
Behind a trailer you can see nothing and be seen by nobody, which is two problems from one position.
The truck driver can't see your vehicle in this position, and your own view of traffic flow is severely reduced.
Trucks have much larger blind spots on both sides than passenger vehicles. Driving in one for any length of time means the truck driver cannot see you at all.
If the truck has to change lanes in a hurry, the space you are in is the space it will use.
If a truck driver needs to change lanes quickly for any reason, a serious crash could occur if your vehicle is in the truck driver’s blind spot.
On the test
How can a driver tell they are in a truck's blind spot?
They cannot see the truck's side mirrors. The mirror test works both ways, and it is the only check you can make from your own seat. 2025 Vermont Driver's Manual, p.43: “Remember, if you can’t see the trucks rear (side) view mirrors then the truck driver can’t see you.”
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.
