Widest Legal Trailer Width
The size of the item to be shipped determines the need for flags or lights on the tractor or trailer. Typically, red flags and yellow lights are required for oversized loads to ensure visibility for other vehicles. Travel companions accompanying an oversized shipment often need to have flags and/or lights. The STAA also regulated the length of commercial vehicles. In 1982, Congress established minimum length standards for most commercial tractors and for double trailers towed behind a tractor. (See discussion from page 2.) Congressional intervention in vehicle length reflected a desire to standardize the application of length along the NN, eliminating any administrative and operational confusion caused by the various state regulations governing the length of commercial vehicles along this element of U.S. highways. Warning flags, red or fluorescent orange, 18 squares, must be affixed to the front and rear corners of the oversized cargo. Additional flags shall be affixed to any extension or projection extending further from the sides of the vehicle and corners.
Note that flag mounting is NOT included in the total width of the load. Total length: 65 feet (without bumper); Trailer length: 40 feet; Length of motorhome: 45 feet; Width: 8 feet (without safety equipment up to 6 inches; for motorhomes, excluding accessories up to 6 inches); Height: 14 feet. Pulling an oversized load requires extensive experience and expertise. It`s not just about having the right driver, the right truck and the right trailer. You also need to understand the required permits and understand the logistics of the situation. Total length: 62 feet, 65 feet with a camping trailer, semi-trailer or parking trailer; Trailer length: 53 feet, 45 feet for recreational vehicles, 28 feet as part of a package; Width: 8 feet 6 inches (only on some roads, excluding safety equipment up to 6 inches); Height: 13 feet 6 inches. Total length: 75 feet (excluding safety equipment and extension cords used for loading beyond the front or rear, in combination for the transport of cars and boats); Trailer length: 45 feet; Length of motorhome: 45 feet; Width: 8 feet 6 inches (without zipped accessories up to 6 inches); Height: 13 feet (14 feet 6 inches on designated roads) (14 feet 6 inches on all roads as of August 10, 2016). Total length: 65 feet (excluding mirrors, safety equipment, transport devices and loading equipment up to 24 inches above the stern); Trailer length: not specified; RV length: 45 feet (excluding mirrors, safety equipment, transportation devices and loading equipment up to 24 inches above the rear); Width: 8 feet 6 inches (without mirrors, safety equipment, turn signals, grip handles, splash and spray suppressors, load-induced tire curvature, position lights, fender extensions, automotive cover devices, tarpaulin and tarpaulin fittings and tie-down assemblies up to 3 inches); Height: 13 feet 6 inches.
Before we get into the key considerations for these types of shipments, let`s first explain what qualifies a wideload shipment. In the United States, a large or oversized load is a vehicle and/or load larger than 2.59 m (8 ft 6 in). Each U.S. state has slightly different requirements for oversized shipments, so it`s important to know each state`s legal requirements. At Hale Trailer Brake and Wheel, Inc., we have knowledgeable representatives at each of our trailer rental locations ready to answer your questions and help you find the right commercial trailer for your transportation needs. In general, the maximum permissible load width is 8.5 feet (102 inches), and the maximum height limit is also 102 inches. The legal length is typically 48 to 53 feet and the maximum weight is about 46,000 pounds. Some trucks may be harder to scale, but 46,000 pounds is usually the norm. Total length: 65 feet (up to 75 feet in certain circumstances); Trailer length: 28 feet 6 inches; Length of motorhome: 40 feet (38 feet for a single-axle semi-trailer; 40 feet for a 2- or multi-axle semi-trailer); Width: 102 inch (up to 6 inch without safety equipment and RV accessories); Height: 13 feet 6 inches (14 feet on designated roads).
There are important differences between wide and oversized loads. First, wide loads are usually too wide loads to meet legal road traffic limits. This usually means anything larger than 8.5 feet (2.6 meters) in width. Oversized loads, on the other hand, are those that exceed the legal limits of length, width, height or weight. Secondly, due to their size and dimensions, wide loads usually have to be transported using special equipment such as low-loaders. Oversized loads can be transported by standard trucks and trailers, although they may require permits and escort vehicles. Finally, large loads are normally only allowed on certain routes previously approved by the competent authorities. Oversized cargo can be allowed on any route, although permits and escorts may also be required here. Overall, wide loads and oversized loads pose challenges in terms of transportation.
However, understanding the key differences between the two can help ensure that your cargo is transported safely and legally. An oversized load is simply any load that exceeds the maximum permissible width, height and/or longitude as defined by each state or province of the United States and Canada.2 See regulations for maximum load limits. Find out what an itinerary measure is. The maximum length allowed on roads, motorways and motorways. Maximum permissible load sizes. Multi-state and regional permits. Devices excluded from length measurement include: (1) devices necessary for loading or unloading which do not extend more than 24 inches beyond the rear of the vehicle; (2) elastic bumpers that do not extend more than 6 inches beyond the front or rear of the vehicles; (3) aerodynamic devices that do not exceed more than 5 feet beyond the rear of the vehicle, provided they do not have the force, stiffness or mass necessary to damage a vehicle or injure a passenger in a vehicle striking a trailer so equipped from behind and do not obscure the taillights or turn signals, the necessary position lamps, identification lights or other safety devices; such as dangerous goods signs or conspicuous markings; and (4) non-proprietary equipment that does not extend more than 3 inches beyond the rear of the vehicle. All devices at the front of a semi-trailer or trailer are excluded from the length measurement. Buoyancy systems for open trailers or semi-trailers are excluded, provided that no part of the system is more than 3 inches from the sides or rear of the vehicle.
For more details on these exclusions, see 23 CFR 658.16 and Appendix D through 23 CFR 658. These rules apply to individual passenger cars (towed or not), commercial vehicles, including tractors for semi-trailers, trailers and buses. Rear-view mirrors and some safety features (such as flags, etc.) may exceed a “reasonable” distance further. Always get official advice on any head start you may have by contacting your state/province DOT office before any move. Local city or county roads may differ from the maximum length, width, height and weight restrictions set out in federal guidelines. The minimum length of the semi-trailer in this package is 14.63 m (48 feet) or grandfathering limit for a particular condition. (See discussion of the length of grandfathered semi-trailers on page 3.) A state cannot prescribe a total vehicle length for a combination tractor and tractor that operates on the NN or reasonable access roads, even if the trailer is longer than the minimum length required by federal law (Figure 2). A State may not impose an overall length on a tractor towing an individual semi-trailer or a limitation of the distance between the axles of such a tractor.
Length restrictions and other regulations have been issued for six types of special equipment: motor and marine carrier combinations, B-train combinations, beverage trailers, maxi cube vehicles, semi-trailers and camels. Total length: 55 feet (65 feet for trailers and boat carriers); Trailer length: 35 feet; Length of motorhome: 40 feet (45 feet on highways); Width: 8 feet 6 inches (without retractable awnings and safety equipment and energy-saving devices up to 3 inches); Height: 13 feet 6 inches. Ultimately, the semi-trailers themselves are limited to a standard width. However, shipping can overcome these restrictions with the right equipment. For example, with a low-loader with the right carrying capacity, you can carry just about anything, even a shipment that stretches 120 inches or more beyond the sides of the tow. These are station wagons consisting of a straight truck and a towing unit, both designed for the transport of goods. The truck has a removable or fixed loading box that can be loaded or unloaded via the next semi-trailer or trailer. To be considered a max-cube vehicle as defined in 23 CFR 658.13(e)(4), no cargo box shall exceed 34 feet (10.36 m) in length, except drawbar or coupling; the distance between the front of the first load box and the rear of the second load box shall not exceed 60 feet (18.29 m), including space; and the total length of the station wagon must not exceed 65 feet (19.81 m), including the space between the loading boxes (Figure 11). The maximum legal dimensions of loads vary from state to state, but any vehicle and cargo that exceeds one or more legal dimensions usually requires a permit that defines the size, weight and type of cargo, as well as the origin and destination of the transport. Fees for permits depend on the type of fee and vary from state to state.
