In Portuguese traffic law, when a light passenger car meets a heavy goods vehicle on a narrow road where passing is impossible, which vehicle must reverse?

Answer and explanation

Correct answer: D. The light passenger car must reverse to allow the heavy vehicle to pass

  1. Step 1: Category hierarchy in narrow passages. Step 2. Article 33 establishes that between different vehicle categories, light vehicles must reverse for heavy vehicles, unless the heavy vehicle is already right next to a passing bay. Answer: The light passenger car must reverse to allow the heavy vehicle to pass. Why not the others: Heavy vehicles have extreme blind spots and maneuvering difficulty reversing; license plates are irrelevant.
