CarAlert

Can someone alert me if I leave my car lights on?

Yes - that is one of the clearest examples of why a community vehicle-alert network can be useful. The catch is that your vehicle needs to be registered before an alert can be routed to you.

CarAlert exists for exactly this awkward gap: you can see the vehicle and its registration, but you do not know the owner and should not need their personal details just to pass on a useful warning.

What to do

  1. 1Register your car with CarAlert.
  2. 2Keep notifications enabled.
  3. 3If another person later sees your lights apparently left on, they can enter your registration.
  4. 4If they send a CarAlert, you can receive the heads-up and check the vehicle.

Important

  • Modern vehicles behave differently, so an observer should say what they see rather than assume the battery will die.
