Which action is involved in HACS Test Conduct by Patrolman?

• A. Ensure vehicles away from sensor
• B. Authorize speed limit enforcement nearby
• C. Deactivate the HACS without notice
• D. Ignore inbound traffic signals

Answer: (A)

Keeping vehicles away from the HACS sensor is the essential action because it prevents interference with the sensor’s readings and ensures the test results reflect normal, uncontaminated operation. Vehicles nearby can obstruct, shield, or introduce vibrations that skew data or cause false triggers, making the test unreliable. By clearing the area, the patrolman creates a controlled environment so the HACS system can be evaluated accurately. The other options would either disrupt safety or the testing process: authorizing speed limit enforcement nearby isn’t part of preparing the test setup; deactivating the HACS without notice compromises safety and monitoring; ignoring inbound traffic signals would create hazards and violate patrol procedures.
