What must you be aware of when joining the motorway?

When joining a motorway in Germany, it's crucial to understand the rules regarding priority and merging. Firstly, the through-driving traffic has priority, which means you must yield to vehicles already on the motorway. This is vital for maintaining the flow of traffic and ensuring safety.

Additionally, it's important to note that on the merging lane, you should ideally match your speed with that of the through-driving traffic rather than exceeding it. This helps with a smoother integration into the existing traffic flow.

While the option regarding the right-hand lane allowing incoming traffic to merge might seem reasonable, under German law, there is no explicit requirement stating that through traffic must give way—especially as the merging driver is responsible for safely merging into traffic. Thus, understanding the priority of through traffic is fundamental to safely navigating onto the motorway.
