It is very important to be familiar with the Trucking Regulation before getting started with Trucking Business. The trucking industry provides an essential service to the American economy by transporting large quantities of raw materials, works in process, and finished goods over land—typically from manufacturing plants to retail distribution centers. Trucks are also important to the construction industry, as dump trucks and portable concrete mixers are necessary to move the large amounts of rocks, dirt, concrete, and other building materials used in construction. Trucks in America are responsible for the majority of freight movement over land, and are vital tools in the manufacturing, transportation, and warehousing industries. A division of the U.S. Department of Transportation, the Federal Motor Carrier Safety Administration (FMCSA) regulates nearly all aspects of the trucking industry. Truck drivers are limited by the number of daily and weekly hours they may drive, the roads and highways they may drive upon, and a lower legal definition of drunkenness. The Federal Highway Administration has established 0.04 percent as the blood alcohol concentration (BAC) level at or above which a CMV driver is deemed to be driving under the influence of alcohol. States maintain a BAC level between 0.08 and 0.10 percent for non-CMV drivers. In some states, trucks also have special speed limits, in addition to restrictions on driving in certain lanes (normally the far left lanes of multi-lane highways). A simple presentation to master the trucking regulations before getting in to the trucking business.
