Built by drivers,
for drivers.
CostaAlert is a free, community-driven road safety network. Drivers report what they see — other drivers vote, and a smart confidence score surfaces the alerts you can trust.
Step 1
Spot something on the road
A speed camera, an accident, sudden roadworks, an unexpected traffic jam. Anything that affects drivers around you.
Step 2
Tap report — share your GPS
One tap captures your location. Pick a category and severity. The community sees your alert in real time.
Step 3
The community votes
Drivers passing the same spot can confirm or dispute the alert. Each vote shifts the confidence score from 0 to 100.
Step 4
Stale alerts disappear automatically
Every category has a smart expiry — police checkpoints clear in 2 hours, roadworks last 24, so the feed stays accurate.
