Look behind — Montana Permit Test
Look behind on the Montana permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Check the traffic behind you, and check more often when traffic is heavy.
In heavy traffic a tailgater or a fast car can close in behind you in seconds.
You need to check more often when traffic is heavy.
It is very important to look behind when you change lanes, slow down, back up, or drive down a long or steep hill.
On a long downgrade, trucks and fast cars build up speed behind you, and you need to know they are there.
It is very important to look behind for vehicles when you change lanes, slow down, back up, or are driving down a long or steep hill.
Check behind you whenever you slow down, especially where a following driver would not expect it, such as at private driveways or parking spaces.
The driver behind does not know you are about to turn into a driveway, so they may still be at full speed.
You must check behind your vehicle whenever you slow down.
When pulling away from the curb, signal, look over your left shoulder, and pull out when it is safe.
A car coming up beside you is in your blind spot, and only a look over your shoulder will show it.
Signal, look over your left shoulder, and pull out when it is safe to do so.
On the test
When should you check the traffic behind you more often?
When traffic is heavy. In heavy traffic a tailgater or a fast car can close in behind you in seconds. Montana Driver Manual, p.53: “You need to check more often when traffic is heavy.”
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.
