Indiana Form M-233IC is used to contact Indiana’s motor carrier permitting office about an oversize/overweight (OS/OW) permit when you need to (1) cancel a requested permit before it is issued, (2) ask questions about a permit (inquiry), or (3) request specific allowed changes to an issued or requested permit. It’s essentially a structured request form: you select the transaction type, provide identifying details (company, contact info, permit number, IDs, and original tractor serial number), and if you’re requesting a change, you complete the change section with the exact updated tractor, dimensions/weight, axle details, route, or time extension as applicable.
Before You Start
- Choose the correct transaction type at the top; it determines which sections you must complete.
- If you’re requesting a permit change, note the timing limits: changes are generally only allowed within 72 hours of the issue date, except annual and 90-day permits (which allow one tractor change before expiration).
- Be aware of fees shown on the form for certain changes (for example, tractor changes, dimension/weight changes, route changes, and time extensions).
