You are driving a road haulage combination vehicle with a maximum authorised mass of 30 t. When may you continue driving after seeing this road traffic sign?

This road sign prohibits vehicles over 7.5 tons from passing, specifically trucks and similar heavy vehicles. The additional plates clarify that the restriction applies to through traffic (Durchgangsverkehr), meaning vehicles just passing through without stopping.

However, exceptions exist:

1. If you must deliver goods to a local resident within the restricted area, you may continue despite the sign.
2. If you are following a designated diversionary route (a special detour intended for such vehicles), you are also allowed to proceed.

The third option about complying with driving and rest periods does not justify ignoring the restriction. German traffic law prioritizes local delivery and official diversion routes as valid exceptions to weight-based bans, but not personal scheduling reasons.

Your correct understanding of these rules will help you recognize when heavy vehicle restrictions apply and when permitted exceptions can be used.
