The exit sign on the highway indicates the point at which drivers can leave the highway or expressway. It is typically marked with a sign that shows the name of the upcoming exit and possibly indicates the direction of the exit (right or left).
In Germany, when you see this sign, you should prepare to exit by checking your mirrors and signaling your intentions early. It's important to reduce your speed gradually and stay in your lane. Once you reach the exit, follow any further signs that guide you onto the road you are entering.
Always be mindful of pedestrians and other vehicles when leaving the highway, and ensure that it is safe to merge into the new road.
