Split speed limits, in which heavy trucks are assigned lower speed limits than lighter, surrounding traffic, are inherently (and provably) less safe than allowing all traffic to travel at comparable speeds. The NMA has joined the Owner-Operator Independent Driver Association (OOIDA) in the past in condemning split limits. See the reasons here.
Indiana HB 1092 – Elimination of lower speed limit for trucks
Elimination of lower speed limit for trucksFull Bill Text
The bill is assigned to the House Committee on Roads and Transportation. It is not currently scheduled for a hearing or vote.
HB 1092 provides that the maximum speed limit for a vehicle having a declared gross weight greater than 26,000 pounds operated on a highway that is: (1) on the national system of interstate and defense highways located outside an urbanized area with a population of at least 50,000; or (2) the responsibility of the Indiana finance authority; is 70 miles per hour. (Current law provides that the maximum speed limit for those vehicles (other than a bus) is 65 miles per hour.)
