Which are automated systems that enforce traffic laws by photographing violations?

• A. Blending
• B. Saturation patrol
• C. Red light cameras
• D. Split-force patrol

Answer: (C)

Automated enforcement uses devices that capture violations without a officer issuing a ticket on the spot. Red light cameras fit this idea because they are placed at intersections and detect when a vehicle enters the intersection after the signal has turned red. When the sensor is triggered, a camera (often with a still photo and sometimes video) records the vehicle and its license plate. That captured evidence is used to mail a citation to the vehicle’s registered owner, which helps deter red-light running and improve safety.

The other options describe policing methods rather than automated, camera-based enforcement. Blending and saturation patrol refer to visible or undercover officer deployment to deter crime, not to automatic photo enforcement. Split-force patrol is a patrol strategy involving different teams, not an automated system for photographing violations.
