Fixed speed-camera alerts: what is legal in France

By Guillaume Leleu Published 26 Aug 2026 3 min read

Key takeaways

A danger-zone / fixed-camera warner is not a radar detector.
OpenRank signals known fixed installations ahead, so you can respect the limit.
No “go through at 129”, no jammer, no live mobile-camera hunt.
This is not legal advice: the Highway Code and CNIL remain the reference.

In France, the “camera alert” debate mixes three things: information about a fixed installation, a wave detector (illegal), and an incentive to exceed the limit. OpenRank only does the first.

What is allowed

Telling the driver they are approaching a known fixed camera — so they can match the speed limit — is a danger-zone warner, not a jammer. That is the frame OpenRank operates in: free speed-camera app with no subscription.

What OpenRank does not do

Detect the waves of a speed gun.
Locate a mobile camera “live” like a scanner.
Encourage driving above the limit (“129 for 130”).
Run GPS continuously in the background: only during a trip you start.

Responsibility

The driver remains responsible for their speed. An alert is not a permit. Product vs Waze / Coyote: OpenRank vs Waze vs Coyote.

This guide summarises OpenRank’s stance. It does not replace the Highway Code or legal advice.

FAQ

Are OpenRank camera alerts legal?

OpenRank warns of a fixed camera ahead to help you respect the limit. It is not a detector of enforcement, nor a tool to dodge checks.

Does OpenRank signal mobile cameras?

No. The app is not a wave detector and does not promise the live location of a mobile check.

Can I rely on the app to drive too fast?

No. Alerts are for respecting limits. Speeding is still speeding, alert or not.
