alt Hacker NewsThe FasTrak scanners above the lane flash the occupancy setting (1, 2, or 3+) on the driver's transponder. It's easy to observe cheating single-occupant vehicles because the flashed number is 3 (a toll-free rate).
For automated enforcement, there's prior art in red light camera systems that mail tickets/violations to the registered vehicle owner.
Yeah, but you pay the full fare with 1 person, half with 2 people, and it's free with 3+.
It's something that isn't straight obvious though. When I got there I also thought that people were just in violation of the people requirement.
I don't get the point of the occupancy reader if there's no hard-requirement of 3+ in the current zone. Maybe there are some stricter HOV-only lanes nowadays? I left the bay area in late 2023
