California DMV Permit Test (Class C)Traffic Signs and SignalsMedium
You are driving on a multi-lane highway and observe a broken white line separating your lane from the lane to your left. What does this pavement marking indicate?
- AYou are in a dedicated turn lane.
- BYou may change lanes if it is safe to do so.
- CYou must not change lanes.
- DThe lane is for HOV traffic only.
Show answer & explanationAnswer & explanation
Correct answer: B. You may change lanes if it is safe to do so.
Broken white lines separate lanes of traffic traveling in the same direction and indicate that you may change lanes if it is safe to do so. Solid white lines mean you should stay in your lane.
Why the other options are wrong
- A. Dedicated turn lanes are typically marked with arrows and sometimes solid lines.
- C. This would be indicated by a solid white line.
- D. HOV lanes are typically marked with a diamond symbol and sometimes specific signage or double solid lines.
Broken White Line
A pavement marking consisting of short white segments with gaps, separating lanes of traffic moving in the same direction.
- Indicates traffic moving in the same direction.
- Permits lane changes when safe.
- Contrasts with solid white lines, which discourage or prohibit lane changes.
Memory trick: Broken lines let you 'break' through, solid lines keep you 'stuck'.
