The recent increase in the number of accidents involving tractor-trailer rigs is due to driver
inexperience. Rising air freights have caused the trucking industry to expand rapidly, resulting in

courses from six to five months, in order to turn out more graduates. This means that graduates do
not get enough hands-on training before receiving their driving certifications.
