On a radar detector, “V/L” typically stands for “V” for “Visual” and “L” for “Laser.” This designation indicates that the radar detector is capable of detecting both traditional radar signals and laser signals used by law enforcement for speed enforcement.
Visual (V): This refers to the radar detection capability for conventional radar guns that emit radio waves to measure speed. These are often in the K, Ka, or X bands, which are common frequencies used by police radar units.
Laser (L): This indicates that the radar detector can also detect laser-based speed enforcement, commonly referred to as LIDAR (Light Detection and Ranging). Laser speed guns use a focused beam of light to measure a vehicle’s speed, which can be more challenging to detect compared to traditional radar.
When a radar detector shows “V/L,” it means that the device is equipped to alert the driver to both types of speed measurement technology that law enforcement may use. This feature is important for drivers who want to be aware of potential speed traps and avoid tickets.
