When operating radar, how far must your patrol vehicle be visible?

When operating radar, it is essential that the patrol vehicle must be visible from a distance of at least 500 feet to ensure that the radar results are reliable and can withstand scrutiny in court settings. This visibility distance allows for accurate speed measurements while ensuring that the driver being monitored is aware of the enforcement officer's presence. The requirement to be at least 500 feet visible contributes to promoting safety, as it ensures that the officer is not attempting to measure speed from an unsafe distance where the radar might yield unreliable readings. Such a standard helps maintain the integrity of speed enforcement operations, providing clear and enforceable documentation if needed for legal proceedings.
