The Federal Motor Carrier Safety Administration regulates many aspects of truck operation and maintenance. FMCSA has promulgated one of the few U.S. regulations relating to ingress/egress systems, FMCSA 399 Subpart L. This regulation pertains only to high cab-over-engine trucks, which are uncommon in the U.S., but some of its recommendations are addressed in the design of conventional cabs. For a summary of FMCSA 399 Subpart L in relation to other standards and guidelines, see the standards page.
SAE International publishes SAE Recommended Practice J185, which provides specific design recommendations for off-highway equipment. These guidelines are widely referenced in the design of on-highway trucks. See the standards page for more info on SAE J185.
The American Trucking Associations' Technology and Maintenance Council (TMC) publishes Recommended Practice 404 B (RP-404B), Truck and Truck-Tractor Access Systems, which provides specific guidance on step and handhold design. See the standards page for more info on TMC RP-404B.
The National Fire Protection Association provides guidance for the design of ingress/egress systems on fire vehicles in NFPA 1901.
MIL-STD-1472f contains quantitative recommendations for step and handhold design, along with recommendations for many other aspects of human-machine interface and work design.
The International Organization for Standards (ISO) publishes several documents relevant to ingress/egress system design, including ISO 2867: Earthmoving Machinery –– Access Systems, and ISO 14122-3: Safety of Machinery: stairs, stepladders, and guardrails.
