Speed on the autobahn has a bearing on liability. For most of the autobahn the recommended speed limit is 130 kilometers per hour. Where there is a posted speed limit, you must adhere to that limit. Where allowed, driving over the advisory speed limit of 130 kilometers per hour is not illegal. However, driving this fast can result in you having increased liability, from the point of view of your car insurance company, in the case of a collision. Some insurers will not pay out for any damages.
