What is not a requirement for a car when transporting items?

When transporting items in a car, a parking disc is not a requirement. This device is primarily used for indicating the time a vehicle is parked in restricted zones where time-limited parking is enforced. It does not pertain to the safety or legal regulations associated with the transport of items within the vehicle.

In contrast, a reflective safety jacket, fire extinguisher, and first aid kit are essential for safety during travel. The reflective safety jacket is required in case of breakdowns or accidents and is important for being visible to other road users. A fire extinguisher is necessary for dealing with potential vehicle fires, and a first aid kit is crucial for providing immediate medical assistance in emergency situations. Therefore, while those items are related to vehicle safety during the transport of goods, the parking disc holds no relevance in this context, making it the correct choice for something that is not a requirement when transporting items.
