What should be noted when loading vehicles?

Your answer is correct because German traffic rules require that loads extending beyond certain limits must be properly marked to ensure safety. Specifically, if a load projects more than 1 meter beyond the retro-reflectors, it must be labeled to alert other road users. Additionally, if a load exceeds a height of 2.50 meters, it is not allowed to project more than 50 centimeters forward from the vehicle. This prevents the load from obstructing the driver's view or creating a hazard. Securing heavy loads is always necessary, so the option stating it is not required is incorrect. Understanding these rules helps prevent accidents related to improperly loaded vehicles.
