The speed of a vehicle occluded by (hidden behind) another vehicle cannot be measured. This occlusion issue does not apply to fixed speed enforcement devices that can be mounted on poles or gantries up to 5-6 meters / 15 -20 ft high using radar as detection method. Fixed and handheld lidar systems reliable up to heights of roughly 2 meters / 7 ft.
