Corporate rules on the railroads I have worked for call for all employees to wear seatbelts in highway motor vehicles... even the hi-rail pickup trucks when on the tracks. When going on track inspections, you are in and out of the truck, constantly... and we violate the rules because the dimwit that wrote the rule never had to deal with continuously hauling himself up and down out of a pickup truck that it a foot higher than usual because it is up on the track and strapping in and out... literally at times every couple hundred feet. We just buckle the belt to the seat... or get used to the alarm constantly dinging.
Work is hard.
