What might a driver argue if speed detection evidence is not documented properly?

If speed detection evidence is not documented properly, a driver may argue that the speed reading is invalid. Proper documentation is crucial because it provides a clear and verifiable record of the speed detection process, including calibration of the equipment used, the conditions under which the reading was taken, and the officer's observations. If any part of this documentation is lacking or unclear, it can cast doubt on the reliability and accuracy of the speed reading itself.

A driver might claim that without adequate documentation, there is no proof that the equipment was functioning correctly or that the speed reading was taken under acceptable conditions. This argument hinges on the principle that reasonable doubt regarding the validity of the evidence should favor the defendant, leading to potential dismissal of the speed allegation. This emphasizes the importance of thorough and precise documentation in speed enforcement practices.
