On April 3, 2006, OSHA revised and ammended the 29CFR1910.178, Powered Industrial Trucks regulation by changing the 1910.178(a)(2) paragraph to read as follows:
All new powered industrial trucks acquired and used by an employer shall meet the design and construction requirements for powered industrial trucks established in the "American national Standard for Powered Industrial Trucks, Part II, ANSI -B56.1-1969", which is incorporated by reference as specified in 1910.6, except for vehicles intended primarily for earth moving or over-the-road hauling.
