Ten years ago, California and Colorado became the first states in the country to legalize marijuana for recreational use. But that doesn’t mean school bus drivers are okay to use it. In school districts that enroll drivers in random drug screening, this can be problematic.

Held to a Higher Standard

School bus drivers have an important role for a student’s day-to-day life: not just transporting them to and from school — but doing so safely. Using marijuana products can jeopardize their ability to make the safest decision when they are behind the wheel, said Chris Ellison, transportation manager for Oregon's David Douglas School District and State Transportation Association Council (STAC) chair for the National Association of State Directors of Pupil Transportation Services (NASDPTS) at the organization’s 54th Annual Conference.

“If people still don't understand what a safety-sensitive position school bus driving is…in the transportation industry, we are held to a higher standard simply because of the responsibility that we have, in and around student safety,” Ellison explained.

The same concerns about recreational use also apply to medicinal use because it’s still a Schedule 1 controlled substance under federal law. The U.S. Department of Transportation’s (DOT) Drug and Alcohol Testing Regulation – 49 CFR Part 40, at 40.151(e) – does not authorize “medical marijuana” under a state law to be a valid medical explanation for a transportation employee’s positive drug test result, according to a 2019 brief from the agency. This means medical review officers will not verify a drug test as negative, even if a physician recommended the employee use medical marijuana.

“It remains unacceptable for any safety‐sensitive employee subject to drug testing under the Department of Transportation’s drug testing regulations to use marijuana,” the brief continued.

Using so-called “full-spectrum” formulations of cannabidiol (CBD) products can also cause users to test positive on a drug screen, according to Quest Diagnostics Drug Monitoring.

 

Marijuana Legalization

Marijuana use — both recreational and medicinal — is legal for adults over the age of 21 in 19 states and Washington, D.C. It is legal solely for medicinal use in 38 states and Washington, D.C. Twelve states have yet to decriminalize marijuana, but some have reforms to change this on November ballots. The bottom line, Ellison said, is that most Americans have access to marijuana.

What Happens When Drivers Test Positive? 

When a driver tests positive on a drug screen, or refuses one, their employer is required to immediately remove them from performing safety-sensitive functions, according to the DOT. Drivers will not be permitted to return to their DOT regulated safety-sensitive functions until they have: 

  •  
  • Undergone an evaluation by a Substance Abuse Professional (SAP). Employers must provide employees with a list of SAPs they can use; 
  • Successfully completed any course, counseling or treatment prescribed by the SAP prior to returning to service; 
  • Undergone a follow up evaluation by the same SAP to determine the driver’s compliance with their recommendations; AND 
  • Provided a breath and/or urine specimen that tests negative for drugs and/or alcohol prior to returning to DOT regulated safety-sensitive functions.

Drivers will also be subject to unannounced follow-up testing for drugs and/or alcohol at least six times during the first 12 months of active service, with the possibility of unannounced testing for up to 60 months (as prescribed by the SAP). The return-to-duty and follow-up drug tests will be conducted under direct observation. 

Test results for random drug screens are confidential. However, a positive test as a result of a major incident like a crash may be reported publicly by law enforcement agencies, resulting in reporting of the results by the local news media, Ellison explained. 

An employer may release the results in the case of certain situations like legal proceedings or grievances but must notify the driver in writing when testing records are released. 

As of January 2020, FMCSA requires employers to report drug and alcohol violations to the Drug and Alcohol Clearinghouse. It also requires employers to check with the Clearinghouse about prospective employees to verify there are no violations before performing safety-sensitive functions, as well as check with the Clearinghouse on current employees at least once a year. 

Marijuana and Pupil Transportation: Educational Resources Available

In 2016, Ellison and a team of other pupil transportation leaders made a training video for school districts in Oregon to illustrate the effects marijuana use by bus drivers can have. That video will be made available to NASDPTS members on the organization’s website after they have logged in. State directors can distribute the videos as they see fit to their local districts.
