FMCSA Drug & Alcohol Testing Requirements

Stay Compliant. Stay on the Road.

The Federal Motor Carrier Safety Administration (FMCSA) requires all CDL drivers who operate commercial motor vehicles subject to DOT drug and alcohol testing to participate in a random testing program. These rules are not optional—failing to comply can result in costly fines, an Out-of-Service order, and damage to your safety rating.

If you operate a commercial vehicle that:

• Requires a CDL, and
• Is operated in interstate commerce (or intrastate if your state has adopted the rules), and
• Is subject to DOT drug and alcohol testing regulations (49 CFR Part 382),
   

…you must be enrolled in a compliant random testing program.

This applies to:

• Owner-operators (must join a consortium) 
• Small fleets 
• Large carriers
   

• Drugs: 50% of your average number of driver positions annually 
• Alcohol: 10% of your average number of driver positions annually
   

Example: If you have 10 drivers, at least 5 will be tested for drugs and at least 1 will be tested for alcohol over the course of the year. Random selections are spread throughout the year and occur without advance notice.

1. Owner-Operators: Cannot manage their own random testing—must be part of a consortium like ours. 
2. Fleets: May manage their own program, but must meet all selection, notification, and recordkeeping requirements. 
3. Testing Must Be Truly Random: All covered drivers have an equal chance of being selected each time. 
4. Immediate Testing: Drivers must proceed to the collection site as soon as they are notified.
