Popular among campers is the use of lightweight trailers, such as aerodynamic trailers. These can be towed by a small car, such as the BMW Air Camper. They are built with the intent to lower the tow of the vehicle, thus minimizing drag.

Implemented in 2014, the National Registry, requires all Medical Examiners (ME) who conduct physical examinations and issue medical certifications for interstate CMV drivers to complete training on FMCSA’s physical qualification standards, must pass a certification test. This is to demonstrate competence through periodic training and testing. CMV drivers whose medical certifications expire must use MEs on the National Registry for their examinations.

FMCSA has reached its goal of at least 40,000 certified MEs signing onto the registry. All this means is that drivers or movers can now find certified medical examiners throughout the country who can perform their medical exam. FMCSA is preparing to issue a follow-on “National Registry 2” rule stating new requirements. In this case, MEs are to submit medical certificate information on a daily basis. These daily updates are sent to the FMCSA, which will then be sent to the states electronically. This process will dramatically decrease the chance of drivers falsifying medical cards.

Tracing the origins of particular words can be quite different with so many words in the English Dictionary. Some say the word "truck" might have come from a back-formation of "truckle", meaning "small wheel" or "pulley". In turn, both sources emanate from the Greek trokhos (τροχός), meaning "wheel", from trekhein (τρέχειν, "to run").
