Key points
Key takeaways
- A radar detector or jammer is prohibited.
- Driving assistance may inform about road conditions without specifying exact enforcement device locations.
- A danger zone prompts speed checks across a stretch of road, not just at a single point.
- On a motorcycle, prepare your app before riding and never operate the phone while in motion.
The Core Rule
What the Law Clearly Forbids
Article R413-15 of the French Road Traffic Code prohibits possessing, transporting, or using a device designed to detect an enforcement unit, disrupt its operation, or evade control. It also covers products that warn about or inform users of such devices’ locations.
A detector identifies the presence or activity of a device; a jammer seeks to interfere with it. A driving assistance app works differently: it uses road data and may report broader zones without turning a control point into an exact location to avoid.
| Service Type | How It Works | Allowed in France? |
|---|---|---|
| Detector | Detects presence or activity of a device | Prohibited |
| Jammer | Disrupts device operation | Prohibited |
| Driving assistance | Informs about road conditions and broader zones | Permitted if service complies with French framework |
| GPS navigation | Guides and displays road information | Permitted without phone handling while riding |
Understanding Alerts
Why an App Shows a Zone Instead of a Point
A danger or control zone represents a stretch of road where the driver must remain especially vigilant. It may correspond to a speed limit, intersection, construction site, reported event, or section prone to enforcement.
This approach avoids reducing alerts to the precise location of a device. For motorcyclists, the appropriate response remains the same across the entire zone: verify posted limits, adjust speed to conditions, and follow actual signage.
A zone alert is a reminder to stay vigilant. It does not replace road signs, law enforcement instructions, or the obligation to obey posted speed limits throughout your journey.
Safety
Using the App Without Handling Your Phone
Service-Public.fr reminds users that holding a phone while driving or wearing an audio device is prohibited. On motorcycles, only helmet-integrated devices are permitted under conditions specified by authorities.
Set up display, volume, destination (if any), and location permissions before starting. If adjustments are needed, pull over in a safe place.
- Securely mount your phone before departure.
- Choose a readable display with minimal interaction required.
- Prefer audio instructions compatible with helmet integration.
- Never confirm a report if conditions do not allow it safely.
Practical Tips
Key Steps Before You Ride
Before setting off, mount your phone on a stable holder, open the app, and adjust volume while the motorcycle is stationary. The screen should remain readable at a glance without requiring complex actions.
During the ride, treat the app as supplementary information. Community data may be outdated or imprecise: road conditions, signage, and official instructions always take priority.
- Set destination and location permissions before starting.
- Enable only alerts you truly need to minimize distractions.
- Pull over safely before adjusting settings or confirming reports.
- Ensure the app and maps are up to date before long trips.
