Violations and severity weights by BASIC
Vehicle Maintenance is described failure to properly maintain a CMV and prevent shifting loads. Example violations: brakes, lights, and other mechanical defects, improper load securement, and failure to make required repairs.. Data would include (1) roadside violations for brakes, lights, and other mechanical defects and improperly secured cargo, (2) crash reports citing a mechanical failure or cargo securement as a contributing factor, or (3) violations from an off-site investigation or an on-site investigation associated with pre-trip inspections, maintenance records, and repair records.
Violation severity weights reflect the relative importance of each violation within each BASIC. These weights cannot be compared or added meaningfully across the BASICs.
In cases where a violation results in an out-of-service order as defined in 49 CFR 390.5, an additional weight of 2 is added to arrive at a total severity weight for the violation.
