Toll signs on 101 report your transponder setting
Ough, this touches a nerve.  The Fastrak system is atrocious and I have been battling it for years.  Let me count the ways:- They took my CC number and just kept replenishing $25 every so often even though it had a big balance already.  Thankfully my card expired so now I'm sloooowly (don't drive much anymore) working my way through the $100+ credit on my account.- It is so hard to check and contest charges.  I had to sent in my complaint with snail mail and IIRC it took a month before I got a reply back that requested information that I already wrote in the first letter doesn't apply.  I gave up at this point.- There is _NO_ way to check the transponder short of just using it and waiting a week for the event to show up on the bill.  My windshield was apparently blocking radio transmissions (I know why, don't tell me) and experimenting with a different location has a crazy long cycle time due to the above.  There days I guess I could do it with a car driving behind me reading what the sign say, but that only works when there isn't much traffic.I hate Fastrak.
