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) should obtain an oversize load permit from the Louisville Public Works Department.

Loads exceeding these dimensions or weights require special permits and may need to follow specific routes to avoid low bridges and other infrastructure limitations in the area.

Escort vehicles are required for loads exceeding 14 feet in width or 15 feet in height on highways within Louisville. Escort vehicles must be equipped with proper signage and lighting as per Tennessee state regulations.

For loads over 18 feet in width or over 120,000 lbs, a police escort may be required. The Louisville Police Department must be contacted in advance to arrange for an escort, with a minimum of 48 hours' notice.

Oversize loads are restricted from traveling during peak traffic hours (7-9 am and 4-6 pm, Monday-Friday) on major highways such as US-129 and US-411.

Seasonal restrictions may apply during heavy snowfall or flooding events, and loads may be required to follow detours or alternative routes as directed by local authorities.

Certain neighborhoods and historic districts have restricted routes; loads must avoid these areas unless specifically permitted.
