An Analysis of the Potential Legal Constraints on the Use of Speed Measuring Devices

摘要

An analysis was made of the potential legal constraints on the use of existing and proposed devices for measuring vehicle speeds. Some of the proposed devices are remote in nature and would operate without a police officer being present. Examination of current law reveals that existing devices, especially radar devices, for the most part face no substantial constraints. However, the use of such devices as VASCAR and stop watches, which are based on time-distance measurements, are prohibited by law in a few states. The use of proposed remote-observation devices is constrained by laws governing speed prosecutions; the chief constraint is that to obtain a conviction, driver must be personally identified and proved responsible.
