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.
The decade of the 70s saw the heyday of truck driving, and the dramatic rise in the popularity of "trucker culture". Truck drivers were romanticized as modern-day cowboys and outlaws (and this stereotype persists even today). This was due in part to their use of citizens' band (CB) radio to relay information to each other regarding the locations of police officers and transportation authorities. Plaid shirts, trucker hats, CB radios, and using CB slang were popular not just with drivers but among the general public.
A relatable reality t.v. show to the industry is the show Ice Road Truckers, which premiered season 3 on the History Channel in 2009. The show documents the lives of truck drivers working the scary Dalton Highway in Alaska. Following drivers as they compete to see which one of them can haul the most loads before the end of the season.It'll grab you with its mechanical problems that so many have experienced and as you watch them avoid the pitfalls of dangerous and icy roads!
DOT officers of each state are generally in charge of the enforcement of the Hours of Service (HOS). These are sometimes checked when CMVs pass through weigh stations. Drivers found to be in violation of the HOS canbe forcedto stop driving for a certain period of time. This, in turn, maynegativelyaffect the motor carrier's safety rating. Requests to change the HOS are a source of debate. Unfortunately, many surveysindicatedriversroutinelyget away with violating the HOS.Such facts have started yet another debate on whether motor carriers shouldbe requiredto us EOBRs in their vehicles.Relying on paper-based log books does not always seem to enforce the HOS law put in place for the safety of everyone.
Business routes generally follow the original routing of the numbered route through a city or town.Beginning in the 1930s and lasting thru the 1970s was an era marking a peak in large-scale highway construction in the United States. U.S. Highways and Interstates weretypicallybuilt in particular phases.Their first phase of development began with the numbered route carrying traffic through the center of a city or town.The second phase involved the construction of bypasses around the central business districts of the towns they began.As bypass construction continued, original parts of routes that had once passed straight thru a city would often become a "business route".
The concept of a bypass is a simple one. It is a road or highway thatpurposelyavoids or "bypasses" a built-up area, town, or village.Bypasseswere createdwith the intent to let through traffic flow without having to get stuck in local traffic. In general theyare supposedto reduce congestion in a built-up area. By doing so, road safety willgreatlyimprove.
A bypass designated for trucks traveling a long distance, either commercial or otherwise,is calleda truck route.
