Bicycle lanes and markings — Massachusetts Permit Test
Bicycle lanes and markings on the Massachusetts permit test — 7 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Bicycle lanes are five feet wide, and motor vehicles may only drive in them when turning on or off the road.
Five feet is barely wider than a rider. Driving in the lane for any other reason takes away the only protected space they have.

When you see a Shared Lane Marking you must look out for bicyclists and leave them enough space when passing.
The marking exists because the lane is too narrow to share side by side. It tells a rider to take the middle of it.

Advisory bicycle lanes are dashed on one or both sides, and motor vehicles may use the space when necessary but must always yield to bicyclists first.
They appear on streets too narrow for a full bicycle lane. The dashes mean shared rather than reserved.

At a red light you should not stop on green pavement.
Green pavement marks where a rider's path crosses yours. Stopping on it puts the car exactly where they are going.

A white diamond symbol means there is a special lane restriction, such as high occupancy vehicle only or bus only.
The symbol is painted on the lane rather than posted beside it, so it is read through the windshield at speed.
A white diamond symbol means there is a special lane restriction, like “high occupancy vehicle (HOV) only” or “bus only.”
Red pavement is used for travel lanes or station stops used by public transit systems.

On the test
How wide is a bicycle lane?
Five feet. Five feet is barely wider than a rider. Driving in the lane for any other reason takes away the only protected space they have. Massachusetts Driver's Manual, p.91: “They are five feet wide.”
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.
