A class 3 vehicle exceeding 2.05 metres in width must have:

Answer: B — Identification and clearing lights

In order to safely operate a vehicle, it is important to be aware of its dimensions. This is especially important in the case of larger vehicles, such as class 3 vehicles that exceed 2.05 metres in width. In order to ensure the safety of both the driver and others on the road, it is required for these types of vehicles to have identification and clearing lights. These lights serve to alert other drivers of the vehicle's size, making it easier for them to anticipate and adjust for passing or crossing lanes. The other options, such as rear fog lights, extra mirrors or a special permit, do not directly relate to the width of the vehicle and do not serve the same purpose of alerting other drivers.
