Cariot to Launch Speed Limit Violation Detection Feature This Fall

New Feature Launch from Cariot

Cariot, a company headquartered in Shibuya, Tokyo, is gearing up to introduce a new feature within its vehicle management system that automatically detects and records speed limit violations on specific roads. This feature is poised for release in the fall of 2026, which aligns with an amendment to Japan’s Road Traffic Act that will lower the maximum speed limit on 'living roads' without central lines to 30 km/h starting on September 1, 2026.

Addressing the Challenge of Speed Limit Awareness

Historically, understanding speed limits across different roads has been difficult due to the existence of both designated speeds and statutory speeds, with each road having its unique regulations. The forthcoming changes aimed to enhance pedestrian and cyclist safety on roads frequently used by residents necessitate tighter speed management, especially for businesses relying on vehicles.

Previously, Cariot offered a generic speed threshold detection (e.g., exceeding 80 km/h), which was inadequate for roads with diverse speed limits. For instance, a violation on a road with a 40 km/h limit by traveling at 70 km/h could go undetected. This presented a significant issue in effective speed management and compliance.

Features of the New Detection System

To tackle this problem, Cariot has developed the speed limit violation detection feature, which utilizes an automatic matching system to compare driving data with road maps. Here’s how the new functionality works:

1. Automated Route Detection: The system captures driving data (location and speed) from onboard devices or mobile apps and matches this information with comprehensive road network data. This automatically identifies the routes driven and cross-references them with their respective speed limits.

2. Automatic Record Keeping of Violations: Upon detecting a speed violation, the system will automatically log details such as the road name, speed limit, maximum speed, and the time the event occurred. This factual documentation assists in ensuring safety driving instructions and facilitates internal reports and audits.
For example: "Route XX / Limit 40 km/h / Maximum XX km/h".

3. Adaptability to Regulatory Changes: The road map data integrated into the system will be continuously updated to reflect recent legislative changes, ensuring that the new 30 km/h regulation for living roads is adhered to.

Looking Ahead: Real-Time Notifications and Further Enhancements

In its future versions, Cariot plans to introduce real-time notifications to administrators during speed violation instances and generate reports on individual driver and vehicle violation trends, turning detected information into actionable insights for daily safety management.

Cariot is committed to listening to user feedback as it progresses, continuously striving to provide robust support for safe and accident-free corporate operations.

Conclusion

Set for launch in the fall of 2026, this feature is a vital step in enhancing road safety and compliance for businesses that rely heavily on vehicle fleets. In addition to the new speed violation detection capabilities, Cariot continues to innovate its vehicle management system, which provides real-time data visibility and operational efficiency—an essential tool for over 400 companies utilizing Cariot’s services as of September 2025.
