A warning triangle must be carried by:
- Commercial vehicles only.
- Correct answer: All motor vehicles, including trailers and semi-trailers, but excluding motorcycles.
- Buses only.
- Two-wheelers only.
Why this is the answer
The correct answer in the official bank: All motor vehicles, including trailers and semi-trailers, but excluding motorcycles.
A warning triangle alerts approaching drivers when a vehicle has stopped on the road because of a breakdown or accident. For this reason it is mandatory equipment in every motor vehicle, including trailers and semi-trailers, not only in buses or commercial vehicles. Motorcycles are exempt from this requirement, so limiting it to two-wheelers is wrong.
