NevadaOversize & overweight permits.

Unless NDOT specifically approves more, a single-trip permit allows:

• Width 14′
• Height 15′
• Length 110′, or 120′ with mechanically steered rear axles
• Overhang 15′
• Valid 5 consecutive days; may cover a round trip, loaded one way

For loads 20′ or more wide or 18′ or more high, NDOT may require the trucking company to survey the route before issuing the permit, covering:

• Safety of travel on the route
• Where obstructions may exist
• A plan to remove or adjust obstructions

Special permits are requested by phone at (775) 888-7410 or (800) 552-2127 during business hours, no later than 10 business days before travel unless NRS 484D.600 provides otherwise. Applications that need special research or inspection by NDOT's engineering staff are charged NDOT's cost.

Single-trip permits: apply online, in person or by phone by 4 p.m. on the last business day before travel. Annual and special permits: no later than 10 business days before travel unless NRS 484D.600 provides otherwise.

NDOT permits cover highways under NDOT's jurisdiction. Cities and counties issue permits for roads under their own jurisdiction.

A load that meets any front trigger needs a lead pilot car; any rear trigger, a following pilot car.

• Front: front overhang over 25′; height over 15′6″; width over 12′ on two- or three-lane roads or during holiday hours or darkness; width over 16′
• Rear: rear overhang over 25′; length over 110′ (120′ with mechanically steered rear axles); width over 14′; width over 12′ during holiday hours or darkness

Over 15′6″ high, the lead pilot car must carry a clearance pole.

NDOT may require one more pilot car and additional utility escorts and traffic control coordinated with law enforcement for:

• Loads wider than 17′ on two- or three-lane roads
• Loads wider than 19′ on roads with four or more lanes
• Loads higher than 16′

A passenger car or a truck with no more than two axles, 16,000 lb GVWR or less and at least 60″ wide, within legal size and weight, equipped with:

• OVERSIZE LOAD or OVERSIZE sign above the roofline, visible front and rear: black letters at least 10″ high (1 5/8″ minimum stroke) on yellow
• Two flashing or rotating amber lights above the roofline beside the sign, or one visible from 500′ in all directions (amber light permit from the Nevada Highway Patrol)
• Placard on each side, visible from 50′ by day, with the pilot car company's name and phone number
• 18″ two-sided STOP/SLOW sign on a 5′ pole
• At least three reflective triangles, three 18″ orange cones and one 5-lb BC fire extinguisher
• Hardhat and high-visibility apparel when outside the car; a two-way radio compatible with the other pilot cars and the truck

A pilot car driver must be at least 18, hold a valid driver's license and be certified through a current flagger course. The permittee must make sure pilot drivers are briefed and trained; failing to warn and direct traffic properly violates the permit.

Keep enough distance, for the speed, traffic, road and weather, to warn the truck driver and other drivers in time. When the load must pull off to let traffic pass, help it stop as far off the road as practicable and direct traffic.

Two or more oversize or overweight vehicles may travel in convoy only when every vehicle's permit authorizes it.

A permitted vehicle may get a Level I North American Standard Inspection by NDOT or police before it moves. Failing it revokes the permit.

Every oversize vehicle displays:

• OVERSIZE LOAD or OVERSIZE signs, visible front and rear: black letters at least 10″ high (1 5/8″ minimum stroke) on yellow
• Solid red or fluorescent orange flags at least 18″ square at each front and rear corner of the vehicle, and of the load when it is wider than the vehicle
• Rear overhang over 4′: a flag at its center (up to 2′ wide) or at each rear corner (over 2′ wide)
• Display signs and flags only when needed; remove them promptly when the move ends

When a permit allows travel in darkness, the vehicle shows steady-burning lights visible from 500′:

• At least two amber lights on the extreme front
• An amber light on each side, near the middle or toward the front
• Rear overhang over 4′: two red lights marking its full width

The original permit rides in the vehicle it covers. A permit shown on a mobile device does not need a signature; paper or printed permits must be signed.

• A faxed or emailed permit counts as the original
• A copy may not be used in another vehicle
• The permit is void if the vehicle exceeds any limit on it

Valid 12 months: up to 14′ wide, 15′ high, 110′ long (120′ with mechanically steered rear axles) and 25′ total overhang, with gross and axle weights set by NDOT's evaluation of the axle configuration and length.

• During hours of darkness, holiday hours or weekends: no more than 12′ wide, 15′ high, 110′/120′ long and 15′ overhang
• Apply at least 10 business days before first travel unless NRS 484D.600 provides otherwise

NDOT may permit homes over 120″ up to 192″ wide (including eaves), on NDOT-designated highways only, with:

• WIDE LOAD signs and red flags on the front of the tow vehicle and the rear of the home
• A 1½-ton or larger dual-wheel truck or tractor, headlights on low beam
• At least 1,000′ between homes moving the same way
• No travel between sunset and sunrise
• Insurance of $100,000/$300,000 bodily injury and $50,000 property damage

NDOT may issue single-trip or annual permits for self-propelled cranes over the legal weight. Send a description and detailed schematic showing height, length, width and weight as transported with the application.

Farmers and ranchers moving their own implements on Interstate or controlled-access highways get free annual (up to 14′ W, 15′ H, 110′ L) or single-trip permits. Implements up to 14′ wide travel in daylight with a following pilot car; wider ones must be hauled.

In an emergency, NDOT or local law enforcement may authorize a move without a permit, even orally. Get the special permit on the next business day.

NDOT may permit licensed movers to move buildings up to 26′ wide if road and traffic allow; wider buildings only for short distances, normally not over 10 miles. The mover must survey the route first.
