When are you allowed to cross a level crossing with flashing lights but no barriers after a train has passed?

When encountering a level crossing with flashing lights but no barriers, German traffic law requires that you do not proceed until the flashing red lights have stopped. This is important for ensuring the safety of all road users. The flashing lights indicate that a train is either approaching or has just passed, and they remain active to warn drivers of potential ongoing danger.

Even after a train has passed, you must wait for the flashing lights to go out before crossing. This is critical as there may be additional trains approaching or other hazards that aren't immediately visible. Therefore, it's essential to adhere to this rule to prevent accidents and ensure safety on the road.
