Indiana Toll Road allows super-heavy and three-trailer combos. This is more than fair.
Mich. allows 160,000# trucks on plenty-o-roads.
The US standard is #80,000#, generally.
What is the max GVW on the Ind. Toll Road?
“Indiana Toll Road allows super-heavy and three-trailer combos. This is more than fair.”
Indiana allows doubles but trailers are restricted to 28’6” and must conform to 80,000# GVW and 34,000# axle weights.
Triples are allowed only on the toll road and only within 15 miles of makeup/breakup point.
They still must conform to 80,000# and 34,000# limits.
