Wyoming allows 36,000 lb on a tandem — above the federal 34,000 — and states no single gross weight figure at all, delegating the Interstate cap to federal law and otherwise offering operators a choice between two tables. Table I, the bridge-formula table, reaches 117,000 lb; Table II tops out at 80,000. A triple axle may carry 42,000 lb.
