Passing hazards and return — Montana Permit Test
Passing hazards and return on the Montana permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Treat a hill or curve as an oncoming vehicle: do not start to pass if you are within one-third of a mile of a hill or curve.
A car just over the crest is invisible until it is in your lane.
This means you should not start to pass if you are within one-third of a mile of a hill or a curve.
It is dangerous to pass where a vehicle is likely to enter or cross the road, such as intersections, railroad crossings, and shopping center entrances.
The car you are passing hides the driver pulling out of a side road into your path.
Such places include intersections, railroad crossings, and shopping center entrances.
Before you pass, look ahead for things that may push other vehicles into your lane: people or bicyclists near the road, a narrow bridge, or ice, potholes, or objects on the road.
The car you are passing swerves out around a pothole and into you.
A narrow bridge or other situation that causes reduced lane width.
When you can see both headlights of the vehicle you just passed in your rearview mirror, it is safe to return to the driving lane.
Cutting back in too soon puts your rear bumper in front of the car you just passed.
When you can see both headlights of the vehicle you just passed in your rearview mirror, it is safe to return to the driving lane.
Do not pass unless you have enough space to return to the driving lane, and do not count on other drivers to make room for you.
A driver halfway through a pass with nowhere to go is stuck facing oncoming traffic.
Space to return - Do not pass unless you have enough space to return to the driving lane.
On the test
How close to a hill or curve may you be and still start to pass?
No closer than one-third of a mile. A car just over the crest is invisible until it is in your lane. Montana Driver Manual, p.67: “This means you should not start to pass if you are within one-third of a mile of a hill or a curve.”
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.
