Passing law — Montana Permit Test
Passing law on the Montana permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
On a two-lane road, a vehicle may exceed the speed limit by 10 mph to pass another vehicle and return safely to the right lane.
A pass held to the limit leaves you in the oncoming lane much longer, facing whatever comes.
Vehicles traveling on a two-lane road may exceed the speed limit by 10 miles an hour in order to overtake and pass another vehicle and return safely to the right lane.
On multi-lane roads, the left-most lane is meant for passing slower vehicles.
When slow cars camp in the left lane, faster ones start passing on the right, where they are hard to see.
On multi-lane roads, the left-most lane is intended to be used to pass slower vehicles.
Passing on the right is legal only when the vehicle you pass is making or about to make a left turn, or on a road with pavement wide enough for two or more lanes going the same way.
A driver being passed on the right may not see you and can change lanes right into you.
Passing on the right is legal only when the vehicle you’re passing is making or about to make a left turn, or on a road with unobstructed pavement wide enough for two or more lanes of vehicles legally going in the same direction as the vehicle you’re passing.
You may not pass on the right by driving off the pavement or main-traveled part of the road, so never pass on the shoulder, paved or not.
Other drivers never expect a car on the shoulder and may pull off the road without looking.
You cannot pass on the right by driving off the pavement or main-traveled portion of the road, which means never passing on the shoulder (whether it is paved or not).
On the test
On a two-lane road, by how much may you exceed the limit to pass and get back into the right lane?
10 mph. A pass held to the limit leaves you in the oncoming lane much longer, facing whatever comes. Montana Driver Manual, p.38: “Vehicles traveling on a two-lane road may exceed the speed limit by 10 miles an hour in order to overtake and pass another vehicle and return safely to the right lane.”
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.
