The intention of a trailer coupler is to secure the trailer to the towing vehicle. It is an important piece, as the trailer couple attaches to the trailer ball. This then forms a ball and socket connection.It allows for relative movement between the towing vehicle and trailer while towing over uneven road surfaces. The trailer ball shouldbe mountedto the rear bumper or to a drawbar, which may be removable. The drawbar secures to the trailer hitch by inserting it into the hitch receiver and pinning it.
The three most common types of couplers used are straight couplers, A-frame couplers, and adjustable couplers.Another option is bumper-pull hitches in which case draw bars can exert a large amount of leverage on the tow vehicle.This makes it harder to recover from a swerving situation (thus it may not be the safest choice depending on your trip).
“ The first original song about truck driving appeared in 1939 when Cliff Bruner and His Boys recorded Ted Daffan's "Truck Driver's Blues," a song explicitly marketed to roadside cafe owners who were installing juke boxes in record numbers to serve truckers and other motorists.” - Shane Hamilton
Compliance, Safety, and Accountability (CSA) are fundamental to the FMCSA's compliance program. The purpose of the CSA program is to oversee and focus on motor carriers' safety performance. To enforce such safety regulations, the CSA conducts roadside inspections and crash investigations.The program issues violations when instances of noncompliance with CSA safety regulationsare exposed.
Unfortunately, the CSA's number of safety investigation teams and state law enforcement partners are rather small in comparison to the millions of CMV companies and commercial driver license (CDL) holders. A key factor in the CSA programis knownas the Safety Measurement System (SMS).This system relies on data analysis to identify unsafe companies to arrange them for safety interventions. SMS is incredibly helpful to CSA in finding and holding companies accountable for safety performance.
The FMCSA has established rules to maintain and regulate the safety of the trucking industry.According to FMCSA rules, driving a goods-carrying CMV more than 11 hours or to drive after having been on duty for 14 hours, is illegal.Due to such heavy driving, they need a break to complete other tasks such as loading and unloading cargo, stopping for gas and other required vehicle inspections, as well as non-working duties such as meal and rest breaks.The 3-hour difference between the 11-hour driving limit and 14 hour on-duty limit gives drivers time to take care of such duties.In addition, after completing an 11 to 14 hour on duty period, the driver muchbe allowed10 hours off-duty.
Driver's licensing has coincided throughout the European Unionin order tofor the complex rules to all member states.Driving a vehicle weighing more than 7.5 tons (16,535 lb) for commercial purposes requires a certain license. This specialist licence type varies depending on the use of the vehicle and number of seat.Licences first acquired after 1997, the weightwas reducedto 3,500 kilograms (7,716 lb), not including trailers.
