Signals and pavement markingsQuestion 91 of 296

A single solid yellow line marks the centre of a two-lane highway. Traffic, sight distance and other conditions are ideal. What may you do?

  1. Never pass, as with double solid lines
  2. Pass only on the right
  3. Pass only if you signal twice
  4. Pass, if the road ahead is clear and it is safe
Show answer

Correct answer: Pass, if the road ahead is clear and it is safe

A single solid yellow centre line does not ban passing. Pass only when the road ahead is clear and every condition is safe.
