Vermont Oversize & Overweight Permits

When Vermont needs a permit

Break 8'6" wide, 13'6" high, or 80,000 lb and the Vermont DMV permits under CVO-110 (23 V.S.A. §1400). Single-trip oversize runs about $48, blanket about $135; overweight climbs from roughly $800 to $10,000 by weight. One escort kicks in at 12' wide, 80' long, or a 15' overhang. At 150,000 lb VTrans runs a mandatory engineering inspection and you file special insurance, so book the move weeks out. Weather voids the permit.

Thresholds, escorts, and curfews

• Legal max before a permit: No permit up to 8'6" wide, 13'6" high, 80,000 lb, and within legal length. Over any one of those and the Vermont DMV issues an over-dimension or overweight permit before the move.
• Escort / pilot car: One escort at 12' wide or more, at 80' long or more, or with a 15'+ overhang. The Commissioner of Motor Vehicles can require two or more. Escort must be at least a compact car with two-way radio contact and a 5-ft 'OVERSIZE LOAD' sign (10" black letters on yellow).
• Superload: 150,000 lb or more triggers a mandatory VTrans engineering inspection and a special certificate of insurance. There is no fixed statutory lead time, so file well ahead; a last-minute superload permit rarely clears in time.
• Travel curfew: Over-width, over-length and over-height travel is daylight only, 30 minutes before sunrise to 30 minutes after sunset; a load that is overweight only and can hold traffic flow speed is not tied to daylight (CVO-110). No permit is issued for a load over 108,000 lb, over 12' wide, or over 100' long on any Saturday, Sunday, or on New Year's, Memorial Day, Independence Day, Labor Day, Thanksgiving or Christmas. For loads 12' wide or greater and 80' long or greater, the permit dies in ice, sleet, freezing rain or sticking snow, and any time visibility drops so the load is not readily identifiable at a quarter mile.
• Permit fee: Single-trip oversize about $48; single-trip overlength about $34; blanket oversize about $135 (plus $8 per added permit). Overweight climbs from roughly $800 (under 150,000 lb) to about $10,000 (over 250,000 lb).
