I do the same as well.
The "Bridge police department" (can't remember their real name) will ticket you if you pass through the FT lanes without a tag. EVEN if you're registred Fast track user. Thing is that on some bridges, they only take picture of the front of the vehicle...
Saw it on the Rich Bridge last month...
The Richmond bridge is screwy.
(...)
Where it gets screwy is as a "carpool" you can *only* use the designated carpool lanes, which on the RBB are lane 3 (the one just to the right of the two FT lanes) and the next to last lane on the far right.
(...)
Oh, and be aware that CHP moto cops hang out at the toll plaza waiting for someone on a bike to bomb through. Ask me how I know.
It gets really screwy because every user of that brigde want to use those 2 lanes even if they are not carpooling!!!!!!!
And Michael: watch out for the same CHP moto cops: they hide in the afternoon under on the bridge in the shade of one of the 2 bridge towers to lidar you...
