A driver must obtain an oversize and/or overweight vehicle permit before traveling on Indiana roads to ensure the safety of the motoring public if his or her vehicle exceeds:

• 13 feet 6 inches in height
• 8 feet 6 inches in width
• 53 feet (semi-tractor-semi-trailer combination) in length; or
• 80,000 pounds gross vehicle weight (subject to axle weights)

OSW provides an online permitting system that allows drivers to request and receive permits at their convenience.
