Slovenian drivers will soon face section speed cameras that measure their average speed over an entire stretch of motorway, with the new system expected to begin operating in September. Instead of recording a vehicle’s speed at one specific location, the system will calculate how fast drivers travel between two points.
The new enforcement method is designed to stop motorists from slowing down only when approaching a traditional speed camera before accelerating again. Cameras will record vehicles at the beginning and end of each monitored section. The system will then use the time needed to travel the distance to calculate the vehicle’s average speed. If that average exceeds the legal speed limit, authorities can process the violation. Slovenian police have previously explained that the technology records vehicles and their registration plates at entry and exit points. The first section speed cameras will be installed on several busy motorway routes across Slovenia. These include the Štajerska motorway between Blagovica and Vransko through the Trojane tunnel area toward Maribor. Two monitored sections are also planned on the Gorenjska motorway between Ljubljana Brod and Vodice toward Kranj. Other locations include the Primorska motorway between Logatec and Vrhnika toward Ljubljana and the Dolenjska motorway near Grosuplje and Ivančna Gorica in the direction of Novo mesto.
The locations were selected based on several factors, including traffic safety, accident patterns, road conditions, congestion and existing speed data. The move forms part of Slovenia’s wider effort to reduce speeding and improve road safety. The country’s National Road Safety Programme also includes section speed measurement among the measures planned for national roads. The goal is to gradually introduce this type of control at multiple locations. Speeding remains one of the biggest dangers on Slovenian roads. During a national speed enforcement campaign in April, police recorded 3,538 speeding violations in just one week. More than 580 of those violations happened on motorways and expressways. In 2025, inappropriate speed was also the leading cause of fatal traffic accidents in Slovenia. According to the Slovenian Traffic Safety Agency, it contributed to 42 percent of deadly crashes.
The introduction of section speed cameras could significantly change how drivers approach some of Slovenia’s busiest roads. Motorists will no longer be able to rely simply on spotting one camera or police patrol and briefly reducing their speed. Instead, they will need to maintain a legal speed throughout the entire monitored route. Every part of the journey between the two cameras will contribute to the final average speed calculation. For drivers, the message is simple: slowing down only when a camera becomes visible may no longer be enough. Once the new system begins operating in September, consistent compliance with speed limits will become more important than ever. The new section speed cameras are intended to encourage safer driving over longer distances and reduce the risks linked to excessive speed on Slovenia’s roads.
