Center lines — Connecticut Permit Test
Center lines on the Connecticut permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Center lines are yellow lines that separate lanes of traffic moving in opposite directions.
Yellow beside you means something is coming the other way, and that is the one thing you cannot share a lane with.
Center lines are yellow lines that separate lanes of traffic moving in opposite directions.
A dashed yellow line separates single lanes of traffic moving in opposite directions, and passing is allowed.
The breaks in the line mean the road ahead can be seen far enough for a pass to be finished.
Dashed Yellow Lines separate single lanes of traffic moving in opposite directions. Passing is allowed.
A dashed yellow line alongside a solid yellow line means passing is permitted on the side of the broken line but not on the side of the solid line.
The line is written for both directions at once, and each driver reads only the half nearest them.

Solid yellow lines may be crossed to make a left turn to or from an alley, a private road, a driveway or a street.
A double yellow is a passing rule, not a wall. Turning across it is exactly what the exception is for.
Solid yellow lines may be crossed to make a left turn to or from an alley, private road, driveway, or street.
Yield lines are used where drivers are required to yield, such as at a mid-block crosswalk.
A yield line marks the place to yield where there is no sign or signal to say so.
Yield Lines are used at locations where drivers are required to yield, such as a mid-block crosswalk.
On the test
What do yellow center lines separate?
Traffic moving in opposite directions. Yellow beside you means something is coming the other way, and that is the one thing you cannot share a lane with. Connecticut Driver's Manual, p.43: “Center lines are yellow lines that separate lanes of traffic moving in opposite 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.
