Beginning the the early 20th century, the 1920's saw several major advancements. There was improvement in rural roads which was significant for the time.The diesel engine, which are 25-40% more efficient than gas engines were also a major breakthrough.We also saw the standardization of truck and trailer sizes along with fifth wheel coupling systems. Additionally power assisted brakes and steering developed. By 1933, all states had some form of varying truck weight regulation.
In 1976, the number one hit on the Billboard chart was "Convoy," a novelty song by C.W. McCall about a convoy of truck drivers evading speed traps and toll booths across America. The song inspired the 1978 action film Convoy directed by Sam Peckinpah. After the film's release, thousands of independent truck drivers went on strike and participated in violent protests during the 1979 energy crisis (although similar strikes had occurred during the 1973 energy crisis).
Medium trucks are larger than light but smaller than heavy trucks. In the US, theyare definedas weighing between 13,000 and 33,000 pounds (6,000 and 15,000 kg). For the UK and the EU, the weight is between 3.5 and 7.5 tons (3.9 and 8.3 tons).Local delivery and public service (dump trucks, garbage trucks, and fire-fighting trucks) are around this size.
The Federal-Aid Highway Amendments of 1974 established a federalmaximum gross vehicle weight of 80,000 pounds (36,000 kg).It also introduced a sliding scale of truck weight-to-length ratios based on the bridge formula. Although, they did not establish a federalminimumweight limit.By failing to establish a federal regulation, six contiguous in the Mississippi Valley rebelled.Becoming known as the "barrier state", they refused to increase their Interstate weight limits to 80,000 pounds.Due to this, the trucking industry faced a barrier to efficient cross-country interstate commerce.
Some trailers canbe towed byan accessible pickup truck or van, which generally need no special permit beyond a regular license. Such examples wouldbe enclosedtoy trailers and motorcycle trailers. Specialized trailers like an open-air motorcycle trailer and bicycle trailers are accessible.Some trailers are much more accessible to small automobiles, as are some simple trailers pulled by a drawbar and riding on a single set of axles.Other trailers also have a variety, such as a utility trailer, travel trailers or campers, etc. to allow for varying sizes of tow vehicles.
