Your Map Is Not the Law — the Road Sign Is

It is easy to trust the speed limit shown on your navigation screen. But that number comes from a database that was last updated weeks, months, or even years ago. The physical sign at the roadside is the one that counts — legally and practically. If the sign and your app disagree, the sign always wins.

Why Map Speed Limits Fall Out of Date

Speed limits change far more often than most drivers realise:

• Roadworks impose temporary limits that can appear overnight and vanish weeks later.
• Reclassified roads — a route upgraded or downgraded changes its default limit.
• New school zones, villages and junctions add lower limits that take time to reach map providers.
• Seasonal limits near coasts, mountains and tourist areas change with the calendar.

Map companies rely on periodic surveys and crowd data to update these numbers. In the Balkans, where road networks are modernising quickly, the gap between the sign and the database can be significant.

Mobile Cameras Move — No Map Can Track Them Live

Mobile speed cameras are set up from parked cars, tripods and hand-held radar guns. They relocate every single day and are deliberately placed where drivers least expect them — just after a limit drop, on a downhill stretch, or at a village boundary. Because they never stay put, no map can show their exact position in real time. What a good app can do is warn you that you are entering a stretch where mobile enforcement is common, and surface live reports from other drivers who have just passed one.

Two Rules That Keep You Safe

1. Obey the physical sign — it is legally binding. If you are fined, "my app showed a higher limit" is not a defence. The sign you drove past is the law.

2. Treat apps as a real-time alert layer, not the source of truth. Navigation and radar apps are excellent for advance warning and awareness, but your eyes on the road come first. Read the signs, then let the app confirm and warn.

How RoadRadar Fits In

RoadRadar is built around this exact principle. It does not replace the road sign — it adds a live warning layer on top of your own observation:

• Alerts for known fixed and average-speed camera zones
• Community reports of mobile cameras and checkpoints, updated as drivers pass them
• Reminders to check the road ahead, not just the screen

Eyes on the Road, App as Backup

The safest driver uses every tool available but trusts the road itself. Watch the signs, keep RoadRadar running for real-time alerts, and never let an outdated map number talk you into speeding.
