Speeding and broken lamps continued to be top concerns last year during roadside enforcement of commercial vehicle safety regulations.

The overall number of roadside inspections was up from 2020, the first year of the pandemic, but remained low by historical standards.

Being familiar with the most common violations can help drivers and motor carriers avoid them.

The following tables list the top 10 violations of driver- and vehicle-related motor carrier safety and hazardous materials regulations as cited during roadside inspections in 2021, as well as:

  • The percentage of those violations that resulted in an out-of-service (OOS) order for the driver or vehicle; and
  • The severity points assigned to each violation in the Compliance, Safety, Accountability (CSA) system.
