of kilometers of roads covered in North America, Europe, Japan, Australia, and New Zealand.
Advancing the future of road safety
One in five road accidents is weather-related. The Euro NCAP 2026 rating protocol introduces a new points system focused on accident prevention, placing greater emphasis on real-time information about driving conditions and local hazards.
Xweather helps automotive innovators meet these new safety standards by delivering timely driver warnings. These include alerts for weather-dependent speed limits, slippery roads, and hazardous weather conditions—updated every 15 minutes across all public paved roads.
By integrating Xweather, carmakers can improve Euro NCAP ratings while enhancing the safety, efficiency, and sustainability of mobility. Trusted by industry leaders including Audi, BMW, Bosch, Hyundai, Mercedes-Benz, NIRA, Porsche, Škoda, and Volkswagen.
Warn drivers about up ahead weather hazards
Since vehicle sensors cannot detect all upcoming local hazards, using external weather data can help warn drivers. The driver may need to take over the driving task if the vehicle is not permitted to operate in adverse weather conditions.
Display correct speed limit during a weather event
In some countries, there are conditional speed limits related to weather, among other conditions. Xweather data can detect all weather events relevant to conditional speed limits.
Achieve a higher Euro NCAP rating
With Vaisala Xweather data, carmakers can gain additional points in the Euro NCAP Safe Driving and Assisted Driving protocols.

Millions of kilometers of roads covered
Vaisala Xweather's Road Weather data covers millions of kilometers of roads in North America, Europe, Japan, Australia, and New Zealand. We model primary and secondary roads separately to reflect the effects of different road surfaces, traffic levels, and maintenance priorities. Bridges are also modeled separately to account for the free flow of air beneath the road surface.
Unlike fleet-sourced data, which often has significant spatial and temporal gaps, our Road Weather data delivers real-time conditions and forecasts for every public paved road 24 hours a day, 365 days a year.
