Show answer & explanationAnswer & explanation
Correct answer: A. You may cross it to make a left turn at an intersection or into a private driveway.
While solid double yellow lines generally prohibit crossing, California law makes an exception for making a left turn at an intersection, into a private road, or into a driveway. This is the only permissible time to cross a solid double yellow line.
Why the other options are wrong
- B. This is generally true, but there is a specific exception for left turns.
- C. While no oncoming traffic makes it safer, it is not the legal condition for crossing a solid double yellow line.
- D. A broken yellow line on your side indicates passing is allowed, which is different from a solid double yellow line.
Solid Double Yellow Line (Left Turn)
A solid double yellow line generally prohibits crossing, but it may be crossed to make a left turn at an intersection, into a private road, or into a driveway.
- Otherwise, crossing is illegal.
- Must yield to oncoming traffic.
- Only when safe and legal to do so.
Memory trick: Double line, don't cross, unless turning across.
