You want to transport goods on a commercial basis or for payment. For which vehicles or vehicle combinations does the holiday travel regulation apply?

In the context of German traffic regulations, the holiday travel regulation is particularly relevant for the transportation of goods. This regulation is designed to manage traffic during peak travel times, such as holidays, and it restricts certain vehicles from operating.

In this case, the correct options relate to vehicles that exceed a maximum permissible mass of 7.5 tons or involve a trailer. These vehicles and combinations are significant because they can contribute to heavier traffic and safety concerns on the roads during busy travel periods.

Specifically:
1. A vehicle with a maximum permissible mass of over 7.5 tons is regulated to mitigate the risks associated with larger, heavier vehicles during peak travel times.
2. A combination with a trailer is also included as it can significantly affect road safety and congestion.

Understanding the impact of these vehicles during holidays can help ensure smoother traffic flow and enhance road safety for all users. It's crucial to recognize all relevant categories when answering such questions to fulfill the legal requirements and adapt to traffic regulations effectively.
