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-dimension travel is generally daylight only, and wide loads are held to sunrise-to-sunset. The permit is void in poor visibility or on slippery roads, and holiday no-move windows apply. Read the exact hours stapled to your permit.
• 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).
