FMCSA Moves to Close Drug OOS Enforcement Gap
FMCSA has opened rulemaking after CVSA said drug-possession out-of-service orders can be hard to enforce once contraband is seized. The proposal would add a 24-hour driving bar similar to alcohol rules.
Rulemaking Starts After CVSA Petition
FMCSA has begun a rulemaking process aimed at closing a drug-related out-of-service enforcement gap flagged by the Commercial Vehicle Safety Alliance. The agency granted CVSA's petition on Sept. 17 and is looking at changes to 49 CFR 392.4, the rule covering drugs and other substances.
The issue is narrower than a general drug-testing update. CVSA said a driver found in possession of drugs can be placed out of service, but the existing drug rule does not clearly make it a separate violation to keep driving while that order is still active.
The Alcohol Rule Has Clearer Language
Alcohol violations already carry a mandatory 24-hour out-of-service period and language that lets inspectors cite a driver who continues operating during that window. CVSA wants similar language added for drug-possession violations.
The enforcement problem can appear after the first stop. If an inspector or officer seizes the controlled substance, a second officer who stops the same driver later may have no contraband in the vehicle to support a new drug-possession violation, even though the original out-of-service order is still active.
What Fleets Should Watch
The proposal would require drivers found in violation of the drug-possession provisions to be placed out of service immediately for 24 hours and explicitly bar them from driving until the order expires. FMCSA Administrator Derek Barrs said the petition gave the agency enough justification to begin rulemaking, but the agency will still review comments before deciding whether to amend the regulation.
For fleet compliance teams, the practical takeaway is to keep roadside-drug enforcement on the audit list alongside clearinghouse checks, driver qualification files and post-stop communication. If the rule advances, dispatchers and safety teams will need clean handoffs so an active out-of-service order does not become a preventable second violation.
