Can cops detect speed while moving?

Yes, in two ways. Radar is capable of determining your speed, and the officer is trained and experienced enough to visually estimate your speed within a couple of mph. Each method will be used to verify the other.

Does a cop have to tell you how fast you were going?

Most officers will tell you how they measured your speed. It’s likely to be by pacing, LIDAR, or radar. Unless they have a department policy that requires this, they are not obligated to show you the readout on the radar or LIDAR device. Some will, some won’t.

Do cop cars have speed sensors?

Unlike police laser, police radar directly determines a vehicle’s speed by measuring the doppler (speed induced) shift of the return of its transmitted frequency (think of the sound you sometimes hear of an approaching or receding train or emergency vehicle).

What to say if an officer asks how fast you were going?

This means when an officer asks you questions such as “do you know why I stopped you,” you should respond “no.” If the officer asks you “do you know how fast you were going,” you should simply answer “yes.” Officers are trained to let you incriminate yourself by letting you admit to violations or admit that you were …

Can a police officer track the speed of a car?

How accurate is Doppler radar on a police car?

If the patrol car is moving, the Doppler radar can accurately measure the speed of a vehicle if it is generally coming toward the patrol car only (but not going the same direction as the patrol car). The difference in calculated speed vs actual speed is always in favor of the violator.

How far behind a police officer should you be pacing?

Bumper pacing becomes more difficult the farther behind the officer is from your car. (The most accurate pace occurs where the officer is right behind you.) But patrol officers like to remain some distance behind a suspect to avoid alerting a driver who periodically glances at the rearview and side-view mirrors.

What does the speedometer reading of a police officer mean?
