When should you operate a flashing yellow lamp above the driver’s compartment?

1. When you are driving a vehicle carrying freight that is wider than the vehicle.
2. When you are driving a connected vehicle.
3. When you are driving a vehicle with a permitted weight of more than 15,000 kg.
4. Correct answer: When the length of the freight or of the vehicle exceeds 20.00 meters.

WhyA flashing yellow lamp above the cab is needed when the freight or the vehicle is longer than 20 meters. Weight or a trailer alone does not require it.
