Alertplates

AlertPlates lets drivers send and receive quick, anonymous alerts using license plate numbers. Whether it’s headlights left on, leaking fluids, a towing or citation waiting to happen, you can give or get a helpful heads-up—no personal info, no messaging, and no tracking.
Only users who opt in can receive alerts. AlertPlates is about creating a community of drivers who look out for one another and help protect parked vehicles.
