90mph motorway speed limit trial set to begin

The Czech authorities are set to follow Spain by introducing a 150kph (93mph) speed limit on one stretch of road. In May 2025, the AP-7 motorway in Catalonia was given a similar speed limit trial on a variable basis.

The move is being trialled on the D3 motorway, which is a 107-mile section of motorway connecting Prague with the Austrian Mühlviertel Expressway (S10) to Linz. The stretch that is gaining the trail is a 31-mile section. This has been chosen as it is, according to the This is Money (TiM) website, as it is a relatively new section of road with very few curves.

Like the Spanish trial, the D3 will be a variable road, with certain conditions taken into account when applying the increased limit. These are things like weather and road conditions, and the volume of traffic using the road will have to be taken into account. When not running at the higher, 93mph speed limit, the road will be restricted to the Czech Republic’s maximum 130kph (80mph) limit will remain.

The speed limit on the action will be governed by the National Traffic Information Centre, according to TiM, and drivers will be notified of the maximum speed via overhead gantries - similar to those that we can see on the UK’s network of ‘SMART’ motorways.

The move indicates that more European governments are exploring innovative ways to reduce journey times and alleviate congestion. But while drivers in the country have applauded the Czech limit, some neighbouring nations are more reticent, especially those neighbours who have spent the last few years lowering speed limits for safety and environmental reasons.
