Steps must be secure, clean, slip resistant, and safe for normal driver access.
Handholds support safe three-point contact when climbing, descending, and working around equipment.
Deck plates and catwalks must be secure, clean, slip resistant, and safe for normal work.
Broken access components should be treated as safety defects and tracked until repaired.
Drivers should inspect steps, handles, deck plates, fuel tank steps, and housekeeping daily.
A practical checklist for steps, handholds, decks, DVIRs, repairs, and injury prevention.
Part 399 matters because access safety prevents driver falls, injuries, delays, and claims.
DispatchHQ helps small carriers organize driver safety, DVIR workflows, maintenance follow-up, injury prevention, inspection habits, and practical safety messaging that protects drivers during daily operations.
