Re: Clearance lighting
The state police might not know, it's a federal requirement. Then again, state police don't always know state laws either.
That link I posted says the center ID lights are required for all vehicles over 80" wide. It doesn't say anything about commercial or non-commercial. Dually pickups have ID lights, even if they're registered with passenger plates. Basically, the lights warn other drivers at night that you're big.
And Smitty, your bus had the lights, the ID lights are the 3 on the top edge of the roof cap, over the "SCHOOL BUS" sign.
