Average-speed calculations render traditional radar detection useless. Your usual Waze confidence just became dangerous on Colorado highways. Colorado’s new Automated Vehicle Identification Systems don’t work like the radar guns your app knows how to spot—they photograph license plates at two separate points, then calculate average speed between them using timestamps. Consider focusing on DIY car fixes to keep your vehicle running smoothly instead of risking costly fines.
How AVIS Outsmarts Navigation Apps
Paired cameras track time and distance instead of instant speed readings.
Unlike traditional radar that Waze crowdsources in real-time, AVIS cameras operate in pairs positioned along highway stretches. Your phone buzzes about speed enforcement ahead, but slowing down at the camera location won’t save you. The system already captured your plate upstream and will photograph it again downstream, mathematically determining whether you averaged 10+ mph over the limit across that distance. This sophisticated approach to monitoring traffic violations represents a significant technological advancement in enforcement.
Where Colorado Deployed These Camera Traps
Construction zones on major commuter routes get priority enforcement.
CDOT activated the first corridor on Highway 119’s Diagonal section between Boulder and Longmont, with warnings starting July 2025 before $75 fines kick in later this year. The I-25 stretch south of Fort Collins through Mead and Berthoud gets cameras starting March 2026, targeting the express lanes construction zone. After 31 work zone fatalities in 2024—nearly double the previous year—legislators passed SB23-200 authorizing this expanded enforcement.
The Legal Framework Behind Camera Expansion
Revenue funds program growth across high-risk Colorado corridors.
The 2023 legislation requires 30-day warning periods and “Camera speed enforcement ahead” signs placed 300+ feet before detection zones. Unlike traditional tickets, AVIS violations carry no license points—just civil penalties that fund the program’s expansion. CDOT plans spring 2026 deployment in school zones and additional high-risk areas, following the model already used by Denver, Boulder, and other Front Range cities.
Adapting to Average-Speed Reality
Legal speed management between camera points becomes the new strategy.
Smart drivers can still game the system legally by maintaining appropriate speeds throughout camera zones rather than relying on last-second slowdowns. Navigation apps aren’t updating to detect average-speed cameras yet, leaving you dependent on visible signage and geographical awareness. As this technology spreads nationwide, the era of radar detector apps providing foolproof speed trap warnings is ending—at least in construction zones where workers’ lives depend on slower traffic.
