Germany is temporarily suspending unlimited speed on several stretches of the Autobahn this summer, imposing a hard cap of 120 km/h to protect drivers from a potentially lethal road hazard. Violating the new limits risks an immediate driving ban.
Ageing infrastructure buckles under the heat
The restrictions are not a political statement against high-speed driving. They are a direct response to an acute structural problem affecting stretches of motorway originally built in the 1980s. According to the German motoring association ADAC, extreme summer temperatures cause the large concrete slabs beneath the asphalt surface to expand under intense pressure. When that pressure becomes critical, the slabs can burst upward through the road surface with considerable force, creating sudden concrete ridges and fractures.
Hitting one of these obstacles at high speed poses an extreme risk of tyre blowouts and serious accidents. Authorities have classified the situation on several routes as a critical safety emergency, making temporary speed restrictions unavoidable.
Which roads are affected
The updated restrictions apply to a number of major Bavarian routes. The A93 south of Regensburg is among the most affected, where the road surface has been officially assessed as being in critical condition. Limits are also in place on the A92 towards Munich, as well as on selected zones in both directions between Freising-Süd and Freising-Ost.
Different limits for different vehicles
For standard passenger cars, the maximum permitted speed across the affected sections is 120 km/h. Drivers towing a trailer or caravan face stricter rules, with limits set at either 100 or 80 km/h depending on the specific approval rating of the vehicle combination.
Motorcyclists face the tightest restrictions of all. Between May and September, two-wheeled vehicles are limited to just 80 km/h on these sections due to the elevated risk of accidents in hot conditions.
Immediate consequences for those who ignore the limits
Drivers who choose to disregard the new limits should expect significant fines. Beyond the financial penalty, speeding violations on these sections can result in an on-the-spot driving ban taking immediate effect. The ban applies within Germany, though it is worth noting that the European Union is currently working on legislation that would extend driving disqualifications across all member states if a driver loses their licence in any single EU country.
