Many drivers—especially new CDL holders or those re-entering the workforce—ask about Truck Companies That Only Urine Test during hiring. The confusion usually comes from mixed policies across fleets and the fear of unexpected screening methods. This guide explains what’s legally required, what varies by company, and how to evaluate employers without risking compliance.
Do Trucking Companies Only Use Urine Tests?
Short answer: Most DOT-regulated trucking companies use urine testing as the primary method because it is federally mandated. However, some companies may add non-DOT tests (like hair) in addition to urine, depending on internal policy.

Under federal rules enforced by the Federal Motor Carrier Safety Administration (FMCSA) and the U.S. Department of Transportation (DOT), urine testing is the standard for DOT drug testing programs.
Important distinction:
- DOT-required tests: Urine only
- Company policy add-ons: Hair, saliva, or other methods (optional)

Why Urine Testing Is the DOT Standard
Urine testing remains the DOT standard because it is:
- Legally defined and standardized
- Widely available nationwide
- Cost-effective for employers
- Backed by decades of data
What DOT urine tests screen for:
- Marijuana (THC)
- Cocaine
- Amphetamines (including methamphetamine)
- Opiates
- PCP
📊 According to DOT testing data summaries, urine testing identifies recent use reliably while maintaining consistent lab procedures across states.
What People Really Mean by “Only Urine Test”
When drivers search for Truck Companies That Only Urine Test, they usually mean:
- ❌ No hair testing at orientation
- ❌ No additional non-DOT screening
- ✅ DOT urine test only
This is a company policy question, not a legality issue. DOT allows urine testing only—but does not forbid extra testing by employers.
Do Some Trucking Companies Require Hair Tests?
Yes. Some medium-to-large carriers choose to add hair testing to their hiring process.
Why companies add hair testing:
- Detects longer-term drug use (up to ~90 days)
- Provides extra screening confidence
- Reduces insurance risk (from the employer’s perspective)
Why others don’t:
- Higher cost
- Limited lab availability in some regions
- Not required by DOT
⚠️ Key point: Even if a company uses hair testing, they still must perform a DOT urine test to meet federal requirements.

Asking the right way matters.

Follow up with:

Step 3: Get It in Writing
Policies can vary by terminal or recruiter—email confirmation helps.
📌 Pro tip: Avoid asking why a company tests a certain way. Focus on process clarity, not judgment.
