RSMo 304.170: 14 ft (168 in) applies ONLY on the interstate highway system and on routes designated by the Missouri Highways and Transportation Commission. On ALL OTHER HIGHWAYS the maximum height is 13 ft 6 in (162 in). The figure shown is the limit that holds everywhere in the state; confirm your specific route before planning to 14 ft.

Road-class dependent — a single number cannot be correct. RSMo 304.170.5 sets 60 ft overall as the DEFAULT, then exempts the interstate system, where the only limit is the 53 ft semitrailer and there is NO overall limit ("THERE IS NO OVERALL LENGTH LIMIT FOR THIS VEHICLE ON THE ROUTES MENTIONED ABOVE" — MSHP's own body text). Under 304.170.11 the commission may extend that to designated non-interstate routes plus 10 miles. ⚠️ The MSHP brochure HEADLINES 60 ft, which under-reports the legal length on the National Network while over-reporting what is legal on an undesignated county road.
