Overview

• Starting May 1, 2025, seasonal speed limits are enforced on sections of the A3, A92, and A93 in southern Germany to mitigate risks from heat-related pavement deformations.
• Passenger vehicles are limited to 120 km/h, while heavy vehicles and motorcycles are restricted to 80 km/h to ensure safety on aging roadways.
• The measures address the increased vulnerability of 1980s concrete slabs to 'blow-ups,' sudden road surface upheavals caused by high temperatures.
• Signage has been installed to clearly mark the affected areas, and the limits will remain in place through September or until full road renovations are completed.
• Authorities will monitor road conditions closely, with the possibility of stricter limits if pavement quality deteriorates further.
