Some states have Dead Red exceptions, which allow a motorcyclist or a bicyclist to run a red light when the actuator doesn't detect it. Most folks will do that anyway, I mean you wait there for the requisite 3 min or whatever, and eventually when there's a break in traffic you just go, but this exception allows you to do that legally.

That particular exception passed in the Missouri Senate but the House never got around to voting on it this year.
