What motor vehicles are subject to the no-overtaking rule indicated by this sign?

This sign combination shows a no-overtaking rule for trucks, with an additional sign underneath that extends this restriction. Here, the rule is: Not only are trucks forbidden from overtaking, but the additional sign means the restriction also applies to buses (coaches) and cars with trailers.

In your quiz, the correct answer was “Coaches or buses.” This matches the sign, because the lower panel specifically shows a bus, so buses (and any vehicles depicted) must also follow the overtaking ban. Single-track vehicles (like motorcycles) and cars without trailers are not included in this restriction.

For future questions: Always check both the main sign and any supplementary plates, as these additional signs can broaden the rule to include more vehicle types.
