Effect of COVID-19 Pandemic [Text Block]	NOTE N: EFFECT OF COVID-19 PANDEMIC The rapid spread of COVID-19 resulted in governmental authorities implementing numerous measures to try to contain the virus, such as travel bans and restrictions, quarantines, shelter in place orders, increased border and port controls and closures, and shutdowns. These measures and the public health concerns resulting from the outbreak severely disrupted economic and commercial activity. The resulting impact on domestic and global supply chains caused slowdowns and reduced freight demand for transportation companies such as ours. Because we have a significant concentration of customers within the automotive industry, our freight volumes and revenues were significantly affected by the closure of North American automotive manufacturing facilities beginning in late March of 2020. Our automotive customers resumed operations during the second quarter of 2020. Any future delays or interruptions of automotive production and other consumer activity affecting our customers, as well as any future wave of the virus or other similar outbreaks could further adversely affect our business. In addition, the implementation of measures to protect the health and safety of our employees, customers, vendors and the general public may disrupt our ability to efficiently manage personnel and operations and to recruit and retain driver and non-driver personnel, which could have a material adverse effect on our operating results. Further, negative financial results, an economic downturn or uncertainty, or a tightening of credit markets caused by COVID-19 or other similar outbreaks could have a material adverse effect on our liquidity and our ability to effectively meet our short- and long-term financial obligations.
