Warning sign meanings — Montana Permit Test
Warning sign meanings on the Montana permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A T Intersection sign means you cannot go straight ahead; the road turns both right and left.
A driver who expects the road to go on may run straight off the end into a ditch.

A black cow on a dark open-range road is almost invisible until you are on top of it.

A LOW CLEARANCE sign means the overpass ahead is low; do not go on if your vehicle is too tall to pass under.
A tall camper or trailer that tries to fit under can tear off its roof on the bridge.
The overpass has a low clearance. Do not proceed if your vehicle is too tall to pass under.
A SCHOOL BUS STOP AHEAD sign warns that there is a school bus stop ahead; begin slowing now.
A bus stopped past a hill can show its lights too late for a fast car to stop.

On the test
What does a T Intersection warning sign tell you?
You must turn right or left ahead. A driver who expects the road to go on may run straight off the end into a ditch. Montana Driver Manual, p.25: “You cannot go straight ahead. Road turns to both right and left.”
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.
