Bicycles in travel lanes — California Permit Test
Bicycles in travel lanes on the California permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A bicyclist traveling slower than the flow of traffic must ride as close as possible to the right curb or edge of the road.
Keeping right leaves the rest of the lane for traffic that is moving faster.
Bicyclists traveling slower than the flow of traffic must ride as close as possible to the right curb or edge of the road, unless:
A bicyclist may leave the right edge to pass a vehicle or another bicycle going the same direction, or when preparing to make a left turn.
A rider about to turn left has to be in the left of the lane first, exactly like a car.
Passing a vehicle or another bicycle in the same direction.
A bicyclist may leave the right edge to avoid a hazard or road condition, or where a lane is too narrow for a bicycle and a vehicle to travel side by side safely.
A rider in a narrow lane who hugs the curb invites drivers to squeeze past with no room.
Avoiding a hazard or road condition.
On a one-way road with two or more lanes, a bicyclist may ride near the left curb or edge of the road.
Nothing is coming the other way, so the left edge is as good a place to ride as the right.
On a one-way road with two or more lanes. In this case, a bicyclist may ride near the left curb or edge of the road.
On the test
Where must a slow-moving bicyclist ride?
As close as possible to the right edge. Keeping right leaves the rest of the lane for traffic that is moving faster. California Driver’s Handbook, p.47: “Bicyclists traveling slower than the flow of traffic must ride as close as possible to the right curb or edge of the road, unless:”
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.
