DOT vs Non-DOT Drug Testing: What Employers in Georgia Need to Know

If you’re an employer in Georgia—especially in trucking, logistics, or manufacturing—understanding the difference between DOT and Non-DOT drug testing isn’t optional. It’s critical for compliance, safety, and protecting your business.

What is DOT Drug Testing?

DOT drug testing is federally regulated under 49 CFR Part 40 and applies to safety-sensitive employees, including:

• Truck drivers (CDL holders)

• Public transportation operators

• Pipeline and aviation workers

These tests follow strict guidelines, including:

• Chain of custody procedures

• Certified labs

• Medical Review Officer (MRO) verification

Failure to comply can result in serious penalties and liability risks.

What is Non-DOT Drug Testing?

Non-DOT drug testing is not federally mandated, giving employers flexibility to:

• Choose testing panels (5-panel, 10-panel, etc.)

• Set company policies

• Test for additional substances

This is ideal for:

• Manufacturing companies

• Distribution centers

• Small businesses
