Ind. Code 9-20-3-3: a vehicle may not exceed a total maximum height of 13 ft 6 in (162 in). ⚠️ The statute states these limitations do NOT require a clearance of that height, and do not relieve owners of vehicles within the limits from liability for damage.

Official source for this height limit →

Indiana Title 9 Art. 20: "A maximum overall length limit is not imposed on a truck-tractor-semi trailer combination." ⚠️ The 60 ft two-vehicle limit applies to NON-tractor combinations. Kingpin-to-rear-axle 43 ft on the state highway system for trailers over 48 ft 6 in.

Kingpin-to-axle 43 ft or less is a condition of the 53 ft trailer allowance.
