Spain Tests 150 km/h Speed Limit in Catalonia

The Spanish Directorate-General for Traffic (DGT) has launched an innovative AI-powered speed management system on the AP-7 motorway, between Maçanet de la Selva and El Vendrell, covering approximately 90 miles.

Previously limited to the national standard of 120 km/h (75 mph), this section now features dynamic speed limits that can reach up to 150 km/h (93 mph) under optimal conditions.

The new system uses artificial intelligence to assess:

Traffic density

Weather conditions

Time of day

Based on these factors, the system sets the most appropriate speed limit in real time:

When conditions are good: the speed limit increases (up to 150 km/h)

When visibility, traffic, or weather worsen: the system can reduce the limit to as low as 60 km/h

Although the measure has sparked some debate — especially regarding the encouragement of higher speeds — authorities maintain that safety is still the top priority, with AI ensuring accurate and adaptive control.

What do you think about this?

Spain is testing a 150 km/h speed limit on a section of the AP-7 motorway in Catalonia using an AI-based system that adjusts speed based on weather, traffic, and visibility.

Some say it improves traffic flow and efficiency. Others worry about increased risks at higher speeds.

Would you support expanding this 150 km/h limit to other highways in Spain?
