Show the correct answer
Correct answer
B. a bus with a trailer.
Explanation
This question is about which vehicle you are not allowed to tow. You are not allowed to tow a bus with a trailer - answer B.
The Road Traffic Act prohibits towing more than one vehicle, except for an articulated vehicle. A bus with a trailer is two vehicles connected together - by towing such a combination, you would be pulling two vehicles at once, and this is prohibited. Before you tow a bus away, the trailer must be uncoupled. A bus with an external boot (answer A) is still one vehicle. An articulated bus (answer C), although it consists of two sections connected by a joint, is one vehicle, so the prohibition does not apply to it - the Act uses the term articulated vehicle for a combination of a power-driven vehicle and a semi-trailer. During towing, the towing vehicle must have its dipped headlights switched on, and the speed must not exceed 30 km/h in a built-up area and 60 km/h outside it.
