Federal rules and state rules
DOT-regulated employers follow the same federal testing rules in every state. For non-DOT programs, state and local laws shape what employers can do, such as which specimens are allowed, how employees must be notified, and how certain substances are handled.
Because these rules vary and change over time, multi-state employers need a testing partner who knows the requirements where their employees work.
