Oklahoma Tractor Trailer Weight and Dimension Limits

Oklahoma has fairly simple and standard set of rules for truck weights and dimensions. LCVs are allowed in Oklahoma, but they have a low allowable gross weight of 90,000 lbs. The 90,000 lbs gross weight is allowable for all combinations on state roads, assuming that bridge requirements are met. Also, Oklahoma allows longer trailers, in both semi-trailer (59’6”) and semi trailer – trailer combinations (29’).
