What does a solid white line across a lane of traffic indicate?

Merge with traffic in the adjacent lane.
Stop and wait for the light to change.
Change lanes only if it is safe to do so.
Do not change lanes or cross the line.

The correct answer is: Do not change lanes or cross the line.

A solid white line across a lane of traffic indicates that drivers are not allowed to change lanes or cross the line. This option is the correct answer because it accurately reflects the meaning of a solid white line. Option A is incorrect because it suggests merging with traffic in the adjacent lane, which is not allowed when there is a solid white line. Option B is incorrect because it implies waiting for a traffic light, which is not relevant to a solid white line. Option C is incorrect because it suggests changing lanes only if safe, but a solid white line indicates that changing lanes is not allowed at all.
