Overview

• The Roads and Motorways Directorate began installing variable speed signs on the D3, with the pilot scheduled to start in late September 2025.
• The trial covers a 50‑kilometer stretch between Tábor and České Budějovice on a newly built section.
• The limit will rise to 150 km/h only when weather and traffic are favorable, automatically returning to 130 km/h when conditions worsen.
• Transport Minister Martin Kupka said authorities will assess public acceptance and any change in crash rates before deciding on broader use.
• Local reports cite 42 variable signs costing about €2.2 million, with potential follow‑up sections on the D1 between Přerov and Ostrava and the D11 near Hradec Králové.
