What happens here
The 'angle of deflection' or 'cosine effect error' is a critical factor in radar gun accuracy. A radar gun provides a 100% accurate speed reading only if the target vehicle is moving directly towards it. If the police officer is positioned at an angle to the traffic (e.g., on the side of the road), the radar gun will measure a speed lower than the actual speed. The officer is supposed to measure this angle and perform a calculation to get the true speed. In court, you should ask the officer what the angle of deflection was when they clocked your speed. If they cannot provide this information or the necessary calculation, it introduces reasonable doubt about the accuracy of the ticket.
Goal: Introduce reasonable doubt by questioning the angle of deflection of the radar gun
