Ultra light trucks. Often produced as variations of golf cars, with internal combustion or battery electric drive, these are used typically for off-highway use on estates, golf courses, and parks. While not suitable for highway use some variations may be licensed as slow speed vehicles for operation on streets, generally as a body variation of a neighborhood electric vehicle. A few manufactures produce specialized chassis for this type of vehicle, while Zap Motors markets a version of their xebra electric tricycle (licensable in the U.S. as a motorcycle).
Heavy trucks. A cement mixer is an example of a Class 8 heavy truck. Heavy trucks are the largest on-road trucks, Class 8. These include vocational applications such as heavy dump trucks, concrete pump trucks, and refuse hauling, as well as ubiquitous long-haul 6×4 and 4x2 tractor units. Road damage and wear increase very rapidly with the axle weight. The axle weight is the truck weight divided by the number of axles, but the actual axle weight depends on the position of the load over the axles. The number of steering axles and the suspension type also influence the amount of the road wear. In many countries with good roads a six-axle truck may have a maximum weight over 50 tonnes (49 long tons; 55 short tons).
The American Trucking Associations initiated a campaign in 1985 to improve the trucking industry's image in the face of declining public opinion. One such move was changing the name of the "National Truck Rodeo" to the "National Driving Championship", because the term "rodeo" seemed to imply reckless driving.
The Federal Motor Carrier Safety Administration (FMCSA) issues Hours of Service regulations.At the same time, they govern the working hours of anyone operating a commercial motor vehicle (CMV) in the United States.Such regulations apply to truck drivers, commercial and city bus drivers, and school bus drivers who operate CMVs. With these rules in place, the number of daily and weekly hours spent driving and workingis limited.The FMCSA regulates theminimumamount of time drivers must spend resting between driving shifts. In regards to intrastate commerce, the respective state's regulations apply.
The USDOT (USDOT or DOT)is considereda federal Cabinet department within the U.S. government.Clearly, this department concerns itself with all aspects of transportation with safety as a focal point.The DOT wasofficiallyestablished by an act of Congress on October 15, 1966, beginning its operation on April 1, 1967. Superior to the DOT, the United States Secretary of Transportation governs the department.The mission of the DOT is to "Serve the United States by ensuring a fast, safe, efficient, accessible, and convenient transportation system that meets our vital national interests and enhances the quality of life for the American people, today and into the future." Essentially thisstates how important it is to improve all types of transportation as a way to enhance both safety and life in general etc.It is important to note that the DOT is not in place to hurt businesses, but to improve our "vital national interests" and our "quality of life". The transportation networks are in definite need of such fundamental attention. Federal departments such as the USDOT are key to this industry by creating and enforcing regulations with intentions to increase the efficiency and safety of transportation.
Throughout the United States, bypass routes are a special type of route mostcommonlyused on an alternative routing of a highway around a town.Specificallywhen the main route of the highway goes through the town.Originally, these routeswere designatedas "truck routes" as a means to divert trucking traffic away from towns.However, this name was later changed by AASHTO in 1959 to what we now call a "bypass".Many "truck routes" continue to remain regardless that the mainline of the highway prohibits trucks.
