someone is impaired and your 
reasonable suspicion testing is offsite, 
you absolutely must not let them 
drive to it. Have an employee drive 
them or arrange a driver to the test 
and then home. Letting someone 
drive, knowing you think they’re 
impaired, is a significant liability risk 
for organizations.
•	 Document, Document, Document: 
Establish a clear process for 
documentation around any activity 
that raises concerns and ensure 
it is applied uniformly across the 
organization.
Triggers for Testing
Triggers for reasonable suspicion 
testing are based on specific 
observations by supervisors. These 
include appearance, behavior, speech, 
and body odor changes that suggest 
impairment. It’s crucial to remember 
that these observations alone do not 
confirm substance abuse and could 
have other explanations.
Navigating State Regulations
With 15 jurisdictions in the U.S. having 
laws around reasonable suspicion drug 
testing, employers must stay informed 
about state-specific regulations. 
These laws vary widely, with states 
like Alabama, Maine, and Montana 
imposing stringent requirements akin 
to federal standards for transportation 
workers, including the Department 
of Transportation (DOT) guidelines. 
Employers must ensure compliance 
not only with state mandates but also 
with DOT requirements for supervisor 
training in recognizing signs of 
substance abuse. Furthermore, several 
states offer incentives for maintaining 
a drug-free workplace, with rebates 
on workers’ compensation premiums 
available to those who comply with 
reasonable suspicion testing mandates.
Best Practices for Implementation
To effectively integrate reasonable 
suspicion drug testing into your 
workplace, consider the following best 
practices:
•	 Monitor Behavioral Changes: 
Stay vigilant for any changes in 
employees’ behavior, appearance, 
or hygiene as potential indicators of 
substance abuse.
•	 Document Observations: We said 
this before, but it’s worth repeating! 
Stay vigilant for 
any changes 
in employees’ 
behavior, 
appearance, or 
hygiene as potential 
indicators of 
substance abuse.
Ensure that your management team is 
well-trained in identifying signs warranting 
reasonable suspicion testing.
