## How do cops prove you were speeding in court?

Most police officers are trained in how to visually estimate the speed of cars. … Rather, they are trained to first visually estimate the speed of the vehicle and then confirm their estimation with the radar unit. This is done because radar gun readings are often inaccurate for two reasons.

Even if the police officer is not targeting your vehicle, your radar detector will be able to detect these electromagnetic signals and the device will signal to the driver in the form of a bleep or blinking light. If you see the signal, you can release the throttle and hit the brakes to reduce your speed.

## How does police radar know which car is speeding?

Since radar guns are considered scientific instruments, their accuracy is substantially based on the device being calibrated adequately. If the equipment is not properly calibrated, it is likely to produce false readings. It is mandatory that the officer is trained to calibrate the equipment.

approximately 300 metres(Speed = Time X Distance) The range of a radar unit is anywhere up to approximately 300 metres. The distance is dependent upon the time of day, the weather, the amount of traffic, the type and size of vehicles involved and the individual strength of the unit.
