Czech transport officials restore 130 km/h limit on Frýdek‑Místek bypass and extend 150 km/h D3 pilot

On 7 July 2025 the speed limit on the Frýdek‑Místek bypass was raised back to the standard 130 km/h after certified noise measurements confirmed compliance with hygiene limits following bridge‑end replacements. Radar units remain installed on the stretch but are not actively monitoring speed, and authorities will conduct additional impulse‑noise checks during full traffic.

Separately, the Ministry of Transport announced that the pilot permitting a maximum speed of 150 km/h on the D3 motorway between Planá nad Lužnicí and Úsilí will continue until the end of the year. The extension aims to gather more data on safety and traffic flow across different seasons. The 150 km/h setting is controlled by variable signage that activates only under favorable visibility, low traffic, and no incident conditions. Initial findings showed a modest increase in average speed and a mixed effect on speed‑limit compliance across lanes.

Both measures are part of ongoing efforts to evaluate higher speed limits on Czech highways while monitoring noise and safety outcomes.
