Rule 49 Part 40 Regulations From the DOT

Simply put, 49 CFR Part 40–otherwise known as Part 40–is a crucial set of regulations established by the DOT that govern drug and alcohol testing in the transportation industry. Part 40 outlines the following as it relates to drug and alcohol testing safety-sensitive employees:

  • Federal Transit Administration (FTA) – Addresses public transportation employees.

  • Federal Railroad Administration (FRA) – Regulates railroad workers.

  • Pipeline and Hazardous Materials Safety Administration (PHMSA) – Encompasses employees involved in the transportation of hazardous materials.

Key Regulations

  • Mandatory drug and alcohol testing – It specifies when and how drug and alcohol testing should be conducted, including pre-employment, random, post-accident, reasonable suspicion, return-to-duty, and follow-up testing.

  • Testing procedures – Outlines the proper methods for sample collection, laboratory testing, and the interpretation of results.

  • Required substances – Defines the substances that are tested, such as marijuana, cocaine, amphetamines, opioids, and alcohol.

  • Chain of custody and documentation – Establishes procedures for maintaining the integrity and documentation of the testing process.

  • Consequences of non-compliance – Details the penalties and actions that can be taken if employers or employees fail to comply with the regulations.

Overall, Part 40 puts in place several key regulations as it relates to the DOT’s overarching drug and alcohol testing program. As the primary federal agency in charge of maintaining safety in the transportation sector, this is a huge undertaking and main thrust of the drug and alcohol testing program.

How Does the DOT Enforce its Regulations?

Having regulations in place is only one part of the equation. In fact, like most regulations, they’re often only as strong as the willingness to enforce them. To that end, the DOT has several mechanisms and arms that enforce its regulations. These include:

  • Agencies – The DOT comprises several agencies, each responsible for specific modes of transportation. These agencies are tasked with creating and enforcing regulations within their domains.

  • Rulemaking – The DOT agencies develop and update regulations through a formal rulemaking process. This process involves public notice, input from stakeholders, and the publication of final rules in the Federal Register. Once a regulation is finalized, it becomes legally enforceable.

  • Inspections and audits – DOT agencies conduct inspections and audits to ensure compliance with regulations. For example, the FMCSA conducts roadside inspections of commercial motor vehicles and driver records. The FAA performs inspections and audits of aircraft and aviation facilities.

  • Enforcement actions – When violations of regulations are identified, DOT agencies can take enforcement actions. These actions may include fines, penalties, sanctions, suspension or revocation of licenses, and orders to cease operations until compliance is achieved.

  • Compliance reviews – DOT agencies conduct compliance reviews of regulated entities to assess their adherence to safety and operational regulations. For instance, the FRA conducts audits of railroad operations and equipment.

  • Data monitoring – Many DOT regulations involve record-keeping and data reporting requirements. Agencies use this data to monitor compliance and identify potential issues. For example, the FMCSA tracks the safety performance of commercial motor carriers through the Safety Measurement System (SMS).

  • Whistleblower protection – The DOT provides protections to employees who report safety violations, fraud, or other wrongdoing in their organizations. These protections encourage individuals to come forward without fear of retaliation.

  • Collaboration with state agencies – State agencies often play a crucial role in enforcing DOT regulations. They may conduct inspections, issue citations, and work in partnership with federal agencies to ensure compliance.

  • Training and education – DOT agencies provide training and educational programs to help regulated entities understand and comply with the regulations. Taking a proactive approach aims to prevent violations.

  • Research and development – The DOT conducts research to inform the development of regulations and improve safety standards. This research helps ensure that regulations are based on the latest scientific and technological advancements.

With its stated goal of keeping transportation safe, the DOT obviously has the full resources of the federal government at its disposal when it comes to enforcing its various regulations. To that end, failing to comply with these regulations can be extremely impactful to your career as an employee or to your company’s operations if you’re in a leadership role.
