What is it?

The ratio of Department of Transport (DoT) Reportable Accidents per 1,000 tractors in a fleet where the SEC (U.S. Securities and Exchange Commission) filing has been made in the last year. The ratio is derived from the total number of DoT Reportable Accidents divided by the total number of tractors in the fleet divided by 1,000 based on the most recent self-reported MCS150 report filing by the fleet. DoT Reportable Accidents are encoded in 390.15 of the Federal Motor Carrier Safety Regulations (FMCSR) and state that an accident involving a commercial motor vehicle that results in any of the following, it must be recorded on an accident register and maintained by the fleet for three years:

  1. A fatality
  2. bodily injury in which someone involved in the accident receives immediate medical attention away from the scene of the accident or
  3. one or more of the vehicles involved in the accident had to be towed from the scene.

What does it tell me?

The DoT does not consider fault or preventability with respect to DoT Reportable Accidents, which is important to fleets since all accidents impact fleet insurance premiums in one way or another. DoT Reportable Accidents are used to determine a fleet safety rating which will be either satisfactory, conditional, or unsatisfactory. This rating is obtained from a formula that takes the number of recordable accidents a fleet has had in the past year divided by the number of million miles driven (DoT Recordable Accidents x 1,000,000/# Miles Driven During Past 12 Months). If the final number is higher than 1.5, the fleet can be given a safety rating of “conditional” but below that the fleet could be given an ”unsatisfactory” rating adversely impact both reputation and economic viability.
