Where are you allowed to park on the left in the direction of travel?

In Germany, parking on the left side in the direction of travel is generally restricted to certain situations. You are allowed to park on the left side in one-way streets because traffic flows only in one direction, so parking on either side does not obstruct opposing traffic. Also, parking on the left is permitted where there are rails (like tram tracks) on the right side. This is because parking on the right would block the rails, so the left side is allowed for parking. However, parking on the left is not allowed simply because parking is prohibited on the right; the rule is about specific conditions like one-way streets or the presence of rails. Understanding these conditions helps ensure safe and lawful parking.
