MS-17 Asphalt Overlays for Highway and Street Rehabilitation. [91][92], According to Schlag, unsafe and older drivers, in particular, would avoid the autobahn because they perceive the high-speed differentials and very fast drivers as scary, and instead congregate on rural roads where the risk of collisions is higher anyway. The concrete for the top-layer is provided via the bottom-layer concrete paver from a receiving hopper with a charging conveyor and placed in front of the second slipform paver, the SP1500. There are sections of the former German Reichsautobahn system in the former eastern territories of Germany, i.e. On speed-unrestricted stretches, an advisory speed limit (Richtgeschwindigkeit) of 130 kilometres per hour (81mph) applies.

The Federal Road Research Institute (Bundesanstalt fr Straenwesen) solicited information about speed regulations on autobahns from the sixteen States and reported the following, comparing the years 2006 and 2008: Except at construction sites, the general speed limits, where they apply, are usually between 100km/h (62mph) and 130km/h (81mph); construction sites usually have a speed limit of 80km/h (50mph) but the limit may be as low as 60km/h (37mph).
