What Are the Rules for CDL Drivers When It Comes to Drug and Alcohol Usage?
Largely, the transportation industry aims to be drug and alcohol free. In accordance with this goal, DOT agencies implemented drug and alcohol testing for transportation employees via the 1991 Omnibus Transportation Employee Testing Act. 49 CFR Part 40 (sometimes shortened to Part 40) is the Department of Transportation’s regulations for how states should conduct drug and alcohol testing.
It’s important to note that CDL drivers do not automatically lose their licenses due to a violation of the drug and alcohol guidelines.
49 CFR Part 40 includes rules for drug and alcohol usage include but are not limited to:
- Permission for employers to conduct urine collection for drug tests
- Permission for employers to perform alcohol tests
- Employees who have violated DOT drug and alcohol regulations to require SAP evaluation. As outlined: “you cannot again perform any DOT safety-sensitive duties for any employer until and unless you complete the SAP evaluation, referral, and education/treatment process set forth in this subpart and in applicable DOT agency regulations.”
49 CFR Part 40 also sets guidelines for the minimum amounts of alcohol and various drugs such as methamphetamines, morphine, and Marijuana metabolites to determine that a truck driver is in violation.

What are DOT SAP evaluations?
DOT SAP evaluations are the required steps that truck drivers that are found to have violated the alcohol and drug use guidelines have to go through in order to resume driving. These evaluations involve a meeting with a medical professional who will help create a personalized plan for recovery.
These substance abuse professionals are responsible for helping drivers address the underlying factors that might have led them to drug and alcohol abuse. In that way, they’re not at all unlike our own team at Southeastern Recovery Center, doing our best to address underlying issues in our patients suffering from substance use disorders.
What Goes Into a SAP Evaluation?

DOT SAP evaluations follow a fairly simple six step process:
1. Initial assessment. This is when the substance abuse professional that you’ll be working with takes the time to understand the initial factors of your drug or alcohol violation. Think in terms of your lifestyle, stressors, and general access to the substance that led to your violation.
2. Evaluation and testing. This is when the SAP digs deeper, looking to learn the full extent of your substance use disorder. Was this a one-time violation, or a pattern? Has dependence or addiction on drugs and alcohol set in?
3. Treatment planning. This is when your substance abuse professional will create the actual personalized treatment plan to help ensure that you can get back to working without losing your CDL license. This will likely include coping mechanisms that teach healthy alternatives to usage of drugs or alcohol.
4. Follow-up evaluations. Follow-up evaluations help your SAP check your progress and ensure that the treatment plan is working as intended.
5. Return-to-duty process. Once a CDL driver is determined to have completed their drug treatment, the substance abuse professional will proceed with the return to duty process. This includes a final drug or alcohol test to help verify the curbing of the substance abuse habit.
6. Aftercare recommendations. Even after a CDL driver has returned to work, the SAP may offer aftercare recommendations in order to help ensure continued improved behavior over time. At Southeastern Recovery Center, we often connect our patients with sober living options and group therapy to help build social connections with individuals who have experienced the same challenges they are.
The process of drug and alcohol addiction for CDL drivers will vary from person to person, but the broad strokes are well-formulated and statistically proven to give drivers the best possible chance for recovery.

The importance of DOT SAP evaluations in Charlotte (and North Carolina at large)
Charlotte, North Carolina is a I-77/I-85 hub, which means we see a high amount of traffic traveling throughout the Southeast. Naturally, it’s in our best interest for these CDL truck drivers to be sober and attentive while on our roads. But when we look at the data:
- More than 72,000 truckers have been taken off the road due to failing strict drug tests.
- Additionally, an estimated 27.6% of drivers use drugs such as stimulants while on the job, despite chronic and high-dose consumption being shown to “decrease driving skills.”
Our community’s drivers to be sober. This means connecting drivers with the care that they need to learn healthier coping mechanisms rather than turning to alcohol or drugs in order to deal with stress or while seeking higher job performance.
Long hours on the road and time away from loved ones can make it difficult for drivers to resist the temptation of drugs, but SAPs in North Carolina are equipped to address all of the unique challenges in the trucking and logistics industry.
