RI is another one, but I believe they also allow 44k on tandems. CA, RI, and FL are the ones with shortest requirements, but there are quite a few states that can ticket if tandems are too far back. WI, MI, IL, IN, among others have laws about it. Not a bridge law it does have to do with cornering. IN has two settings, one for interstate and another off interstate.
I think IL and IN kingpin regs only apply to non designated state routes. The 2013 Road atlas doesn't list a kingpin setting for either state for interstate/national network routes.
