Kingpin Laws by Stategeorge
Some states have been granted exemptions to federal length standards and have therefore been allowed to apply higher limits than the STAA standard. These exceptions are referred to as „grandfathering“; While federal laws require states not to be able to set trailer length below 53 feet on interstate and access highways, states are free to allow trailers under 53 feet on roads that are not funded by the federal government. Here`s some good news: When the Surface Transport Assistance Act of 1982 was enacted, it provided that „no state shall establish, maintain or enforce any trade regulation imposing a restriction on the length of a vehicle of less than forty-eight feet on the length of the tractor used in a semi-trailer.“ on each section of the National System of Interstate and Defense Highways and the qualified classes of highways of the primary system of federal assistance. G-Town can play a role here, but I think Maryland is the only state that`s really strict about how well the tandems move forward. Maybe NY, PA and NJ, but not as bad as Maryland. These guys are going to blow up the tape measure. It`s important to pay close attention to the distance that applies – in some states you measure from the union pin to the center of the rear axle, but in other states you measure from the royal pin to the center of the group of rear axles. Light commercial vehicles are a type of station wagon truck that only works in states where trucks over 80,000 pounds are allowed. These are combinations of three or four units that contain at least one complete trailer (48 feet or less) or three short trailers. *If greater than 48`, the distance between the stair pivot and the centre of the rear axle group must not exceed 43` At Hale Trailer, our commercial trailer experts are ready to assist you throughout the trailer rental or purchase process.

To be honest, the only concern I really have is California. I`m trying to be legal, but I`ve never tried to get a sender to top up when I`m a few holes away (but I`ll do it for Cali). We never drive in California, so I go to the most restrictive states I`m going to cross in terms of length, which is usually 41 feet. Fortunately, most of our trailers are marked at 40, 41 and 42 feet, but a few have been incorrectly marked lol. Note that the length specifications for car and boat carriers exclude front and rear overhangs. No state may require a rear overhang less than 4 feet or a front overhang less than 3 feet. North Carolina — 41 feet to the rearmost axle or halfway between the two rear axles — is only allowed on highways and designated highways. The following table is a summary of semitrailer length laws by state: Better known as the 18-wheeler, the five-axle tractor-trailer is the best-known commercial vehicle in the United States. The tractor (i.e. the engine) is either a sleeping cabin or a day cabin.
Sleeping cabins have a berth or small saloon in the tractor. They are typically used for long-distance operations. Day cabins have a shorter wheelbase and are used for short-distance operations such as delivery and collection. The freight unit of a tractor-trailer usually ranges from 40 to 53 feet in length; However, some states allow semi-trailer lengths up to 59′6″. Maryland — 41 feet in the middle of the rear tandem axles — is only allowed on highways and designated roads. Semi-trailers are often the most cost-effective way to transport goods from one point to another. However, if you cross the borders of one state, a trailer length that is perfectly legal in one state could be prohibited in another. If you familiarize yourself with the length laws for semi-trailers by state, you won`t have any nasty legal surprises. California is the one that is most mentioned, where the limit is 40 feet. Thus, from the royal pin to the center of the rear axle can not exceed 40 feet in length. The purpose of the section is „to identify a national network of roads accessible to vehicles registered under the provisions of the Surface Transportation Assistance Act of 1982 (STAA), as amended, and to impose national guidelines governing the size and weight of trucks and buses.“ With this law, the federal government sets minimum requirements for the national grid, which the Länder must authorize. Florida – 41 feet between King Pin and the center of the rear axle or group of rear axles on all roads except state highway network roads that are restricted by the DOT or roads restricted by local authorities.
Since that time, all states except Hawaii have allowed 53-foot trailers; However, many states that had a maximum of 48 feet have added a distance limit between pivot and rear axle when trailers larger than 48 feet are used (see below). States regulate this distance to control the wheelbase and turning radius of the assembly. New York City – trailers over 48 feet to 53 feet permitted only on I-95 between I-287 and I-295, on I-295 between I-295 and I-495, and on I-495 between I-95 and the Nassau-Queens County line; King-pined in the centre of the rear axle or group of rear axles limited to 43 feet.
