Illinois Oversize Annual Permit | Oversize Overweight Load Annual Permits


The Illinois Department of Transportation has the authority to issue special permits with respect to highways under its jurisdiction for loads that cannot be reasonably dismantled or disassembled or are otherwise non-divisible. The permits may be issued as single-trip permits or for limited continuous operation (annual permits) and must indicate on which routes the vehicle may travel. They also may establish time limitations, limit the number of trips, or include other restrictions. Permitted vehicles are allowed a scale tolerance of up to 2,000 lbs. on a single axle, 3,000 lbs. on a tandem axle, and 5,000 lbs. gross weight above the permitted limits (Ill. Rev. Stat. ch. 625, §5/15-301[a] – [c], [f]).

The Department also has the authority to authorize, at its discretion, the movement of a vehicle in violation of any size or weight requirement that would not ordinarily be eligible for a permit if extreme necessity is shown that the vehicle and load should be moved without unnecessary delay. This discretional authority is limited to shipments of livestock, hazardous materials, liquid concrete in a mobile cement mixer, or hot asphalt (Ill Rev. Stat. ch. 625, §5/15-301[l]).
