All oversize loads entering Knox County, which includes the City of Knoxville, must conform to the requirements set by the Tennessee Department of Transportation (TDOT).

In general, any vehicle over 12 feet in width, 13.5 feet in height, and within the Class 3 weight category (over 120,000 lbs but not exceeding 150,000 lbs) should obtain an oversize load permit from the Tennessee Department of Transportation and comply with local regulations enforced by the Knoxville Public Works Department.

The Knoxville Public Works Department requires that all oversize loads be routed to avoid downtown areas and residential neighborhoods whenever possible, to minimize disruptions and ensure public safety.

In Knoxville, escort vehicles are required for oversize loads that exceed 14 feet in width or 15 feet in height. Escort vehicles must be equipped with appropriate warning lights and signage as per TDOT regulations.

For loads that require a police escort, arrangements must be made through the Knoxville Police Department's Traffic Division. A minimum of 48 hours' notice is required for police escort scheduling, and fees apply based on the number of officers required.

To apply for an oversize load permit in Knoxville, applicants must submit their requests through the Tennessee Department of Transportation's Permit Office website or by contacting them directly. Additional local requirements may be coordinated through the Knoxville Public Works Department.

Documentation required includes detailed load specifications, proposed route, and any additional information requested by the permitting authority.

Knoxville has time-of-day restrictions for oversize loads; generally, travel is not allowed during peak hours (7-9 am and 4-6 pm) on weekdays.

Seasonal restrictions may apply during heavy construction periods or events that significantly impact traffic flow. It's advisable to check with the Knoxville Public Works Department for up-to-date information.

Certain routes through Knoxville are restricted for oversize loads, including those through historic districts or areas with low clearance bridges. Alternative routes must be planned in advance.

The standard permit fee for oversize loads in Tennessee is $40, with additional fees based on the complexity of the route and the size of the load. For Knoxville, there may be additional local fees.

Fees vary by load size and weight; for example, wider or heavier loads may incur higher fees due to the need for additional escorts or route planning.
