Bicycle lanes — California Permit Test
Bicycle lanes on the California permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Bicycle lanes are for bicyclists only, run alongside vehicle traffic, and are usually marked by a single solid white line and signs.
The lane is the only strip of road a rider can count on, and a car in it leaves them nowhere.
Bicycle lanes are for bicyclists only and run alongside vehicle traffic.
It is illegal to drive in a bicycle lane except to park where that is permitted, to enter or leave the road, or to turn within 200 feet of an intersection.
Each exception is short and ends quickly, which is what keeps the lane usable for the rider behind you.
It is illegal to drive in a bicycle lane unless you are:
A separated bikeway is physically separated from motor vehicle traffic and is for the exclusive use of bicyclists.
Posts or a curb between the lanes take the guesswork out of it for the driver and the rider both.
Separated bikeway: Is physically separated from motor vehicle traffic and for exclusive use of bicyclists.
Shared roadway bicycle markings alert drivers that bicyclists can occupy the lane.
They tell you the rider ahead is not in your way. The lane is theirs to use as well.
Shared roadway bicycle markings: Alert drivers that bicyclists can occupy the lane and help bicyclists maintain a safe lane position in traffic.
Check your blind spots before entering a bike lane.
A rider going twenty miles an hour is beside your back wheel before the mirror ever shows them.
NOTE: Check your blind spots before entering a bike lane.
On the test
Who are bicycle lanes for?
Bicyclists and nobody else. The lane is the only strip of road a rider can count on, and a car in it leaves them nowhere. California Driver’s Handbook, p.17: “Bicycle lanes are for bicyclists only and run alongside vehicle traffic.”
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.
