  3. CShare the road with motorcycles.
  4. DMotorcycle parking is available ahead.
Show answer & explanation

Correct answer: B. Motorcycles are prohibited from using this road or lane.

This is a regulatory sign indicating a prohibition. The diagonal line through a symbol generally means 'no' or 'not allowed'. Therefore, this sign means that motorcycles are prohibited from using the designated road or lane.

Why the other options are wrong

  • A. This is incorrect; the diagonal line indicates prohibition, not permission.
  • C. This is incorrect; 'Share the Road' signs typically show a car and bicycle with text, without a diagonal line.
  • D. This is incorrect; parking signs have a distinct 'P' symbol.
