It isn't. It never has been and I'm certainly not the only motorcyclist that has never been charged for using it. I use all of the Express Lanes on a motorcycle all the time. You're never going to be charged as the state is required to make those lanes free for motorcycle use in order to receive federal highway funds. They're absolutely not going to jeopardize that over whether or not a motorcyclist was carrying a transponder.
I don't mean to imply you're lying/wrong, it's just odd that if that's the case, I wonder why they went through the trouble to split the motorcycle-specific FAQ into "required" and "not required" like that.
