49 CFR Part 40<\/a><\/strong>\u00a0<\/span>and\u00a0<\/span>49 CFR Part 382<\/a><\/strong>, this includes:<\/p>\n
- \n
- CDL drivers operating vehicles over 26,001 lbs.<\/li>\n
- Drivers transporting hazardous materials requiring placards.<\/li>\n
- Drivers of passenger vehicles designed to carry 16 or more people (including the driver).<\/li>\n<\/ul>\n
It\u2019s important to note that even part-time, seasonal, or intermittent drivers are covered if they perform
safety-sensitive functions. A common mistake carriers make is overlooking these employees, assuming only
full-time CDL holders need to be in the program. Failing to include all required employees can expose your
company to significant liability during a DOT audit or after an accident.<\/p>\n[\/et_pb_text][et_pb_heading title=”Develop a Written Drug & Alcohol Policy” _builder_version=”4.27.4″ _module_preset=”default” title_level=”h2″ global_colors_info=”{}”][\/et_pb_heading][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n
Your program begins with a\u00a0<\/span>written policy<\/strong>\u00a0<\/span>\u2014 the foundation of compliance. DOT regulations require that this policy clearly explain:<\/p>\n
- \n
- Which employees are subject to testing.<\/li>\n
- When testing will occur (pre-employment, random, post-accident, reasonable suspicion, return-to-duty, and follow-up).<\/li>\n
- What substances will be tested (marijuana, cocaine, opioids, amphetamines, PCP, and alcohol).<\/li>\n
- The consequences of a positive test or refusal.<\/li>\n<\/ul>\n
See FMCSA guidance on\u00a0<\/span>Employer Responsibilities<\/a><\/strong>.<\/p>\n
This isn\u2019t just a legal formality. A clear, well-communicated policy builds trust with employees, sets expectations, and demonstrates a company\u2019s commitment to safety. For many fleets, distributing the policy and collecting signed acknowledgments is the first opportunity to engage drivers in a conversation about compliance.<\/p>\n

Before a driver can take the wheel in a safety-sensitive role, DOT regulations require a\u00a0<\/span>negative pre-employment drug test<\/strong>. Employers must also check the\u00a0<\/span>FMCSA Clearinghouse<\/a><\/strong>\u00a0<\/span>for any past violations. This dual step ensures you\u2019re not putting someone behind the wheel who is already prohibited from driving.<\/p>\n
While alcohol testing is not required at this stage, many carriers choose to include it. Doing so helps set the tone for a zero-tolerance safety culture from day one. Consider the scenario of a driver being hired without proper checks, only to later learn they were prohibited in the Clearinghouse \u2014 the compliance consequences could be severe.<\/p>\n
It\u2019s also worth noting that the pre-employment test must be conducted using a DOT-regulated collection process and a certified laboratory. Employers should keep detailed records of the test date, results, and Clearinghouse query for each driver. A common mistake is allowing a driver to begin safety-sensitive duties before the negative test result is back, which constitutes a violation. By building in a standard waiting period for results and integrating Clearinghouse checks into your hiring workflow, you can avoid costly errors.<\/p>\n

Random testing is one of the most visible and important compliance tools. DOT requires employers to:<\/p>\n
- \n
- Maintain a scientifically valid random selection process.<\/li>\n
- Test 50% of drivers annually for drugs.<\/li>\n
- Test 10% of drivers annually for alcohol.<\/li>\n<\/ul>\n
Note that the percentages are minimums and companies can exceed these rates. The DOT can also increase or decrease the rates each year.<\/p>\n

DOT regulations require supervisors to be trained to recognize the signs of drug and alcohol misuse. At minimum, this includes\u00a0<\/span>60 minutes of alcohol training and 60 minutes of drug training<\/strong>.<\/p>\n
Training isn\u2019t just about checking a box. It equips supervisors with the confidence to act when safety may be at risk. For example, a driver who smells of alcohol after lunch or exhibits erratic behavior must be evaluated. Without proper training, supervisors may hesitate to act, putting the company \u2014 and public safety \u2014 in jeopardy. Trained supervisors know how to document their observations and take the right steps quickly.<\/p>\n

After certain accidents, DOT requires prompt testing. Specifically, a CDL driver must be tested if:<\/p>\n
- \n
- They receive a citation for a moving violation in an accident involving a fatality, injury requiring medical treatment away from the scene, or disabling vehicle damage.<\/li>\n
- They are involved in a fatal accident, regardless of fault.<\/li>\n<\/ul>\n
Time is critical:\u00a0<\/span>alcohol tests must be conducted within 8 hours, and drug tests within 32 hours<\/strong>. Employers should have procedures in place \u2014 ideally with a TPA partner \u2014 to ensure a collection site or mobile collector can be dispatched quickly. A common pitfall is failing to document why a test was not completed within the time window, which itself is a compliance violation.<\/p>\n
