Illinois Vehicle Code section 15-113 is the reviewed penalty starting point for overweight violations; exact amount depends on the cited subsection and court record.
Illinois has strong official sources for legal weight limits and IDOT permit
authority. The fine and statewide seasonal fields are intentionally conservative
until a specific current official penalty or seasonal restriction page is tied to
the data model.
Illinois Vehicle Code section 15-111 uses a weight-distance formula approach
that ties allowable weight to axle spacing and the number of axles in a group.
This means the applicable limit for a given Illinois move is not always a single
flat number — it depends on the vehicle configuration reviewed against the
statute. Illinois also restricts Interstate operation to federal size and weight
standards, while non-Interstate roads follow the Illinois Vehicle Code provisions
which can differ by road class, posting, and season. Seasonal weight restrictions
have historically applied to certain Illinois road categories; use official IDOT
materials for current status before dispatch.
How to verify this yourself
Open Illinois Vehicle Code section 15-111 for the weight calculation. Use IDOT’s
OS/OW permit page before any over-legal movement. For a ticket, compare the
actual citation with the current penalty section rather than relying on this
summary.
