Vehicle check brakes and lights — Montana Permit Test
Vehicle check brakes and lights on the Montana permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Have a mechanic check your brakes when they make a lot of noise, smell funny, or the brake pedal goes to the floor.
Brakes that grind or sink to the floor can give out just when the car ahead stops short.
When your brakes are making a lot of noise, smell funny, or the brake pedal goes to the floor, have a mechanic check them.
Turn signals, brake lights, taillights and headlamps should be checked from outside the vehicle.
From the driver's seat you cannot tell that a brake light has burned out.
Make sure that turn signals, brake lights, taillights, and headlamps are operating properly. These should be checked from outside the vehicle.
Driving with your headlights on all the time helps other drivers see your vehicle, day and night.
A gray car on a gray afternoon can blend into the road until it is too close to miss.
Driving with headlights on all the time helps other drivers see your vehicle during the day and at night.
If other drivers often flash their headlights at you, or you have trouble seeing at night, have a mechanic check your headlights.
A headlight aimed out of line lights up the oncoming driver's eyes instead of the road.
If you are having trouble seeing at night, or other drivers are flashing their headlights at you frequently, have a mechanic check the headlights.
On the test
Which of these is a sign your brakes need a mechanic?
The brake pedal goes to the floor. Brakes that grind or sink to the floor can give out just when the car ahead stops short. Montana Driver Manual, p.12: “When your brakes are making a lot of noise, smell funny, or the brake pedal goes to the floor, have a mechanic check them.”
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.
