Hanson Trucking understands that little things make a difference

I was driving past Hanson Trucking today and noticed they had put up a new sign.

Airline pilots who have flown millions of miles still use a checklist. Why wouldnt truck drivers do something similar?
This sign (see below) helps that happen.

Not rocket science, but if it saves one extra trip to a mill because something was forgotten, the fuel savings alone will pay for the sign, plus improve the company’s performance, and perception at the mill. Smart.
