More following distance — Montana Permit Test
More following distance on the Montana permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
When you have a heavy load or are pulling a trailer, leave more space ahead, because the extra weight increases your stopping distance.
A loaded trailer pushes the car forward when you brake, and the usual gap runs out.
When you have a heavy load or are pulling a trailer - The extra weight increases your stopping distance.
When it is hard to see ahead because of darkness or bad weather, increase your following distance.
In fog you spot the brake lights ahead late, and only a long gap makes up for it.
When it is hard for you to see ahead because of darkness or bad weather, you need to increase your following distance.
When following emergency vehicles, leave extra space: police vehicles, ambulances, and fire trucks need more room to operate.
An ambulance that stops or turns without warning needs room around it, not a car on its bumper.
When following emergency vehicles - Police vehicles, ambulances and fire trucks need more room to operate.
Leave extra space when stopped on a hill, because the vehicle ahead may roll back when it starts up.
A car that rolls back a few feet on a steep hill lands on the bumper of the car stopped too close.

On the test
Why should you leave more space ahead when pulling a trailer?
The extra weight increases stopping distance. A loaded trailer pushes the car forward when you brake, and the usual gap runs out. Montana Driver Manual, p.65: “When you have a heavy load or are pulling a trailer - The extra weight increases your stopping distance.”
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.
