Shared center lane sign — Maine Permit Test
Shared center lane sign on the Maine permit test — 2 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A Shared Center Lane - Left Turn Only sign marks a lane only for left-turning vehicles; it is not for through traffic or for passing.
A car using the center lane to pass meets a car coming the other way to turn left in it.
It is not for through traffic or for passing other vehicles.
Traffic traveling in either direction may use a shared center left-turn lane.
A driver who thinks the lane is his alone pulls in nose to nose with a car turning the other way.
Traffic travelling in either direction may use this lane.
On the test
What may you use a shared center left-turn lane for?
Left turns only. A car using the center lane to pass meets a car coming the other way to turn left in it. Maine Driver’s License Manual, p.54: “It is not for through traffic or for passing other vehicles.”
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.
