Reserved lanes — Connecticut Permit Test
Reserved lanes on the Connecticut permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Reserved lanes are marked by signs stating that the lane is reserved for special use.
The sign is the authority. A lane that merely looks empty is not a lane you may use.
Reserved lanes are marked by signs stating that the lane is reserved for special use and often have a white diamond posted at the side of the road or painted on the road surface.
A lane marked transit or bus is for bus use only.
A car in a bus lane holds up a vehicle carrying fifty people, which is the point of reserving it.
“Transit” or “bus” means the lane is for bus use only.
A lane marked bicycle is reserved for bicycles.
It exists so riders are out of the traffic stream, and a car parked in it sends them straight back into it.
“Bicycle” means the lane is reserved for bicycles.
A diamond-shaped marker indicates a lane reserved for high occupancy vehicles, meaning vehicles with more than one person in them.
The diamond is the only marker that says who may use a lane rather than how the lane is driven.

Signs are posted beside a high occupancy vehicle lane saying how many people must be in the vehicle.
The minimum is set lane by lane rather than statewide, so the sign is the only place the number appears.

On the test
How is a reserved lane identified?
By signs stating the lane is reserved for special use. The sign is the authority. A lane that merely looks empty is not a lane you may use. Connecticut Driver's Manual, p.44: “Reserved lanes are marked by signs stating that the lane is reserved for special use and often have a white diamond posted at the side of the road or painted on the road surface.”
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.
