Compliance Guide

Overview

Use the steps below to maintain DOT compliance and manage your DOT Drug & Alcohol Testing Program.

Adding Drivers

Drivers must complete a pre-employment DOT drug test after a full Clearinghouse Query and Drug & Alcohol Policy requirements have been completed.

• Drivers are automatically added to the random testing pool and become eligible for random selection once negative pre-employment DOT drug test results are reported by the Express Labs MRO (Medical Review Officer)
• DOT requires a new pre-employment DOT drug test when hiring a new driver, if a driver has not been in a random testing pool for 30+ days, or when reactivating a driver who was previously deactivated after being randomly selected

Deactivating Drivers

DOT requires employers to immediately deactivate drivers — and owner-operators before being selected — if they are no longer active or unavailable for random testing (terminated, on leave, vacation, etc.).  Failure to promptly deactivate inactive drivers may result in unnecessary random selections and compliance issues.

• Deactivate Drivers - View Instructions

Active Drivers List

Express Labs provides an updated Active Drivers List on the 1st of every month to review your Active Drivers List to ensure inactive drivers have been removed to prevent unnecessary random selections.  DOT also requires current driver license information to order tests.

• Download your Active Drivers List anytime in Certificates & Driver List
• Deactivate Drivers and Add Drivers Licenses - View Instructions

Random Testing

The Express Labs member portal is the official source for all random selection notifications.  Random selections are emailed and posted to member accounts each January, April, July, and October.

• If an email notification is not received, members are responsible for logging into their account to review posted random selections on February 1st, May 1st, August 1st, and November 1st.
