Top 10 DOT Violations: A 101 Guide for Fleet Managers

It’s no small feat to manage a fleet of trucks and maintain compliance. When you add Department of Transportation (DOT) regulations into the mix, trucking is even more complicated. DOT violations can disrupt operations, increase costs, and harm your company’s reputation.

The Federal Motor Carrier Safety Administration (FMCSA) sets the rules of the road that all carriers and fleets follow to ensure safety on the public roads. Accidents happen, and when they do, fleets must report them in the correct way to avoid fines and fees.

That’s because DOT violations impact your Compliance, Safety, and Accountability (CSA) scores, influencing your fleet’s reliability and eligibility for contracts. CSA scores are made up of data collected from inspections, crash reports, and violations across seven key categories, known as BASICs (Behavior Analysis and Safety Improvement Categories). DOT violations add points to the BASIC criteria of your CSA score and may result in FMCSA interventions.

For fleet managers, understanding these violations and implementing strategies to prevent them is critical to staying ahead. Let’s explore the most common violations and how to manage your entire fleet with a focus on safety, compliance and profitability. 

Top 10 DOT Violations to Prevent
