In effect, the formula reduces the legal weight limit for shorter trucks with fewer axles (see table below). For example, a 25-foot (7.6 m) three-axle dump truck would have a gross weight limit of 54,500 pounds (24,700 kg), instead of 80,000 pounds (36,000 kg), which is the standard weight limit for 63-foot (19.2 m) five-axle tractor-trailer.

In the United States, commercial truck classification is determined based on the vehicle's gross vehicle weight rating (GVWR). The classes are numbered 1 through 8. [ 2 ] [ 3 ] Trucks are also classified more broadly by the Federal Highway Administration (FHWA), which groups classes 1 and 2 as light duty , 3 through 6 as medium duty , and 7 and ...
The Texas Legislature created the Texas Highway Department in 1916 to administer federal highway construction and maintenance. In 1975, its responsibilities increased when the agency merged with the Texas Mass Transportation Commission, [3] resulting in the formation of the State Department of Highways and Public Transportation.
Overlength limits vary depending on the type and the configuration of vehicle, but the overall maximum forward distance (i.e. the length from the front of the vehicle to the centre axis of the rear axle set) is 9.5 m (31 ft 2 in), the overall maximum single vehicle length is 12.6 m (41 ft 4 in) (some buses can be longer), and the overall ...
Beltway 8, a state highway maintained by the Texas Department of Transportation (TxDOT), runs mostly along the frontage roads of the tollway, only using the main lanes where they are free: between Interstate 45 (I-45, North Freeway) and Interstate 69/US Highway 59 (I-69/US 59, Eastex Freeway); and between US 90 (Crosby Freeway) and I-10 ...
The city should set limits on emissions from certain buildings, using an approach already in place in New York, according to the report from the Urban Land Institute Chicago.
A falling weight deflectometer (FWD) is a testing device used by civil engineers to evaluate the physical properties of pavement in highways, local roads, airport pavements, harbor areas, railway tracks and elsewhere. The data acquired from FWDs is primarily used to estimate pavement structural capacity, to facilitate overlay design or ...
The first state to implement a weight law was Maine, which set a limit of 18,000 pounds (9 tons; 8,200 kg) in 1918. Two types of loads may result in overweight trucks: divisible and non-divisible. A divisible load is a load which can be easily divided into smaller parts, such as products that are shipped on pallets, automobiles or grains.
