Adding Drivers Instructions

Adding Drivers Process

Clearinghouse Query → Drug & Alcohol Policy → Drug Test → Negative Result → Driver Added

Overview

Send drivers for a pre-employment DOT drug test after completing a full Clearinghouse query and Drug & Alcohol Policy requirements.

When Drivers are Added to the Random Pool

Drivers are automatically added to the random pool (and eligible to be randomly selected) once negative pre-employment DOT drug test results are reported by the Express Labs MRO (Medical Review Officer).

Step 1 – Clearinghouse Registration & Query – View Instructions

• Employers must conduct a full query in the FMCSA Clearinghouse to confirm drivers have no violations and are cleared to drive
• Both employers and drivers must be registered in the Clearinghouse to conduct full queries

Step 2 – Drug & Alcohol Policy – View Instuctions

• DOT regulations require drivers to receive a signed and dated Drug & Alcohol Policy that complies with 49 CFR Part 382 and 49 CFR Part 40
• Employers should keep the original signed copy of the policy in their files

Step 3 – Pre-Employment Drug Testing – View Instructions

• Order drug tests online (QPassports) through your Express Labs account
• Or use Quest paper forms provided by Express Labs
• Drivers must bring the QPassport or Quest form to the collection site
• Express Labs does not accept drug test results from other consortiums or third-party programs
• Your company name and Express Labs must be listed on the drug test result

Step 4 – Supervisor Training Course

DOT requires employers (and owners who hire drivers) to complete Supervisor Reasonable Suspicion Training to hire drivers.  The online training course can be ordered through your Express Labs account (left-side tabs)

• This requirement applies to employers, safety supervisors, and owner-operators who hire drivers
• Training enables supervisors to recognize the signs and symptoms of drug and alcohol misuse

Pre-Employment Testing Requirements

• DOT requires a new pre-employment drug test to hire a new driver.
• DOT requires a new pre-employment drug test if a driver has not been in a random pool for 30+ days.
• DOT requires a new pre-employment drug test to reactivate a driver who was deactivated after being randomly selected.
