Speed cameras that flash red typically indicate that a vehicle has been detected exceeding the speed limit.

It ultimately depends on the specific situation and the purpose of the camera. A red light camera is designed to capture images of vehicles that run red lights, while a speed camera is intended to catch vehicles that are exceeding the speed limit. Both types of cameras are used to enforce traffic laws and improve road safety. It's important for drivers to be aware of these cameras and to always obey traffic laws to avoid receiving a ticket. **
