FMCSA Moves to Close the Drug Out of Service Loophole
Transport Topics reports FMCSA granted a CVSA petition to close a gap in the drug rule. Here is what it means for your drivers, your liability and your rate.
FMCSA moves to close a drug out of service loophole
On September 25, 2026, Transport Topics reported that the Federal Motor Carrier Safety Administration has granted a petition from the Commercial Vehicle Safety Alliance to rewrite the federal rule on drugs and other substances, 49 CFR 392.4. FMCSA granted the petition on September 17. The change is aimed at a gap most drivers never think about, and it matters for anyone who carries their own authority and their own truck insurance.
Here is the gap in plain terms. A driver caught with drugs can be placed out of service today. But the drug rule does not spell out that the driver is barred from driving while that order is in effect. The alcohol rule does. It carries a mandatory 24 hour out of service period and language that lets an officer cite a driver who keeps rolling before the time is up.
Why the order was hard to enforce
CVSA laid out the problem in its petition, as Transport Topics described it. At the first stop the officer seizes the drugs. If the driver pulls back onto the highway anyway and gets stopped again down the road, the second officer finds nothing in the cab. With the contraband already gone, there is no fresh ground to write a new out of service order, and the rule gives no clear hook for citing the driver for ignoring the first one.
The fix FMCSA is now pursuing would borrow the alcohol language. A 24 hour out of service period, and a flat statement that driving during it is a violation. Granting a petition is the start of the rulemaking process, not the finish, so nothing changes at the roadside yet. FMCSA still has to publish a proposal and weigh public comments before any final rule.
Why an underwriter cares about an out of service order
For a small fleet, the new rule is less about what an officer can write and more about what a plaintiff's attorney can prove. Picture a driver placed out of service for drugs who keeps driving and then causes a crash an hour later. The lawsuit will not stop at the driver. It will ask what the carrier knew, when it knew it, and why the truck was moving. That is the heart of a negligent entrustment or negligent supervision claim, and it lands on your commercial auto liability policy.
Once the rule makes it an explicit violation to drive on a drug out of service order, that fact becomes even easier to put in front of a jury. A carrier that let it happen looks like it ignored a direct federal order, which is about the worst position you can defend from.
How it shows up on your insurance
Drug and alcohol violations sit in their own category in FMCSA's safety data, and underwriters read that history closely at new business and at every renewal. One driver with a drug violation can change how a market looks at a one to five truck operation, and a repeat problem can push you toward fewer markets and higher premiums. Our guide on what commercial truck insurance costs walks through how driver history feeds the rate.
There is also the federal filing side. The MCS-90 endorsement that backs your authority can require your insurer to pay an injured member of the public even in situations your policy would otherwise exclude, and then look to you to pay it back. A crash tied to a driver who ignored an out of service order is exactly the kind of loss where that reimbursement fight can start.
What a small carrier should do now
Treat every out of service order as a hard stop in writing. Put it in your driver policy that the truck does not move until the order is lifted, and that drivers must call you the moment one is issued. Run the Drug and Alcohol Clearinghouse queries the rules already require before a driver starts and every year after. Keep your inspection reports and the proof of how you handled them. If you ever have to defend a claim, a clean paper trail is the difference between a bad day and a policy limit loss. If a crash does happen, a strong physical damage policy protects the truck itself while liability sorts out the rest.

Common questions
What is the drug out of service loophole FMCSA wants to close
Under the current drug rule, a driver found with drugs can be placed out of service, but the rule does not explicitly bar driving while that order stands. Transport Topics reported on September 25, 2026 that FMCSA granted a CVSA petition to add a 24 hour out of service period and an explicit ban on driving during it, matching the alcohol rule.
Is the new drug out of service rule in effect yet
No. FMCSA granted the petition on September 17, 2026, which starts the rulemaking process. The agency still has to publish a proposal and review comments before any final rule takes effect.
Can a driver drug violation raise my truck insurance premium
It can. Underwriters review driver and inspection history at new business and renewal, and drug and alcohol violations weigh heavily for a small fleet. If you want to see where you stand, get a truck insurance quote or call or text 423-264-4255.
Who is liable if a driver keeps driving on an out of service order and crashes
The driver is, but the lawsuit usually reaches the carrier too, arguing it knew or should have known and let the truck move anyway. That claim runs through your commercial auto liability policy, which is why a written hard stop policy for out of service orders matters.
