Shared center lane — Connecticut Permit Test
Shared center lane on the Connecticut permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A shared center lane is reserved for making left turns, and for U-turns where they are permitted, and it can be used by vehicles traveling in both directions.
It is the one lane in America that cars enter from opposite directions on purpose, which is why it is only for turning.
These center lanes are reserved for making left turns (or U-turns when they are permitted), but can be used by vehicles traveling in both directions.
A shared center lane is marked on each side by solid yellow and dashed yellow lines.
The solid line on the outside says do not drive through it, and the dashes say you may cross to turn.

In some areas the shared center lane becomes a reversible lane during rush hours, so be sure you can enter the lane and that it is safe before you do.
The same paint means different things at different hours, and the only way to know is to read the signs.

On the test
What is a shared center lane used for?
Making left turns from either direction. It is the one lane in America that cars enter from opposite directions on purpose, which is why it is only for turning. Connecticut Driver's Manual, p.44: “These center lanes are reserved for making left turns (or U-turns when they are permitted), but can be used by vehicles traveling in both directions.”
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.
