# Drug and Alcohol Testing for Truck Drivers

Drug and alcohol testing for truck drivers follows DOT rules with certified labs. Learn trucking drug test types and CDL driver testing options. Call (877) 731-6362.

Drug and alcohol testing for truck drivers involves specific federally regulated urine and breath tests designed to detect substances that impair safe driving. These tests include urine drug screens under 49 CFR Part 40 and breath alcohol tests. AMH Nationwide handles test orders routed to national labs with MRO review. Call (877) 731-6362 to schedule testing.

TEST TYPE 1

## 1. Urine Drug Testing Under DOT Regulations

[Urine](https://amhnationwide.com/urine-drug-testing/) drug testing is the primary method used for federally regulated drug and alcohol screening of truck drivers operating commercial motor vehicles (CMVs). The Department of Transportation (DOT) enforces urine testing protocols under [49 CFR Part 40](https://www.transportation.gov/odapc/part40), which specify collection procedures, cutoff levels, and laboratory standards.

This test detects substances including marijuana (THC), cocaine, amphetamines, opioids, and phencyclidine (PCP). The standard urine drug screen employs immunoassay followed by gas chromatography-mass spectrometry (GC-MS) confirmation for positives.

Cutoff levels for initial screening are set at 50 ng/mL for THC metabolite, 150 ng/mL for cocaine metabolite, 1000 ng/mL for amphetamines, 2000 ng/mL for opiates, and 25 ng/mL for PCP. Confirmatory levels are lower, ensuring accuracy.

AMH Nationwide coordinates specimen collection at one of five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, or ExperTox. All non-negative results undergo review by a certified Medical Review Officer (MRO) to verify test integrity and medical explanations.

Regulated by DOT under 49 CFR Part 40

Detects THC, cocaine, amphetamines, opioids, PCP

Cutoff levels aligned with federal standards

MRO reviews all positive or non-negative results

Collection at certified national lab sites

This urine test is mandatory for [pre-employment](https://amhnationwide.com/pre-employment-hair-testing/), random, post-accident, reasonable suspicion, [return-to-duty](https://amhnationwide.com/dot-return-to-duty/), and follow-up testing for CDL drivers.

TEST TYPE 2

## 2. Breath Alcohol Testing for CDL Drivers

Breath alcohol testing is the standard method for alcohol screening of truck drivers subject to DOT regulations. It uses federally approved breath alcohol testing devices that measure blood alcohol concentration (BAC) via exhaled breath.

The legal limit for commercial drivers is a BAC of 0.04% or higher, which constitutes a positive test. Testing occurs during pre-employment, random, post-accident, and reasonable suspicion events.

AMH Nationwide arranges breath alcohol testing at certified collection sites that use DOT-approved evidential breath testing devices (EBTs). These devices provide immediate results, and any positive or non-negative result triggers further evaluation and MRO review.

Because breath testing is non-invasive and provides rapid results, it is preferred for alcohol screening in the DOT safety-sensitive workforce.

Measures BAC via exhaled breath

Positive threshold is 0.04% BAC or above

Used for pre-employment, random, post-accident testing

Conducted with DOT-approved breath testing devices

Results reviewed by a certified MRO

Breath alcohol testing is essential to confirm sobriety before allowing truck drivers to operate CMVs.

TEST TYPE 3

## 3. Hair Follicle Testing for Non-DOT Trucking Drug Screening

Hair follicle testing offers an alternative drug testing method for trucking companies and drivers not subject to DOT regulations or for pre-employment screening outside DOT mandates.

This test detects a broader range of substances and can identify drug use over a 90-day [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/), unlike urine tests which generally cover only 1-3 days for most drugs.

Hair specimens are collected by cutting small samples close to the scalp and sent to national labs for analysis using gas chromatography-mass spectrometry (GC-MS).

Commonly detected drugs include marijuana, cocaine, amphetamines, opioids, PCP, benzodiazepines, and barbiturates.

AMH Nationwide facilitates hair testing through its national lab network but emphasizes that hair testing is not valid for DOT-mandated safety-sensitive roles where urine and breath tests are required.

Detects drug use over up to 90 days

Suitable for non-DOT pre-employment or random screens

Analyzes marijuana, cocaine, amphetamines, opioids, and more

Samples collected by cutting hair near scalp

Not accepted for federally regulated CDL testing

Hair testing provides a longer detection window but is supplemental to federally mandated urine and breath testing for truck drivers.

## Choosing the Right Drug and Alcohol Test for Truck Drivers

AMH Nationwide recommends DOT-regulated urine and breath testing for federally mandated safety-sensitive drug and alcohol screening of truck drivers. For non-DOT testing needs, hair or extended panels may be appropriate. Contact AMH at (877) 731-6362 to discuss specific testing requirements and arrange collection at certified national labs.

TEST TYPE 4

## 4. Panel Options for Trucking Drug Tests

Trucking drug test types vary in the number and type of substances screened. The standard DOT panel tests for five drug classes: marijuana, cocaine, amphetamines (including methamphetamine), opioids, and PCP.

Non-DOT panels may include extended panels such as 10, 12, or 13-drug screens adding benzodiazepines, barbiturates, methadone, propoxyphene, and others, depending on employer requirements.

Cutoff levels for each panel conform to federal or laboratory standards to ensure consistent detection thresholds.

AMH Nationwide can arrange custom panels through national labs based on client needs, but all DOT testing must meet or exceed the federally mandated 5-panel standard.

Testing panels impact cost and detection scope, so callers should specify the substances of interest when scheduling.

DOT standard 5-panel drug screen

Extended panels test additional substances

Panels affect detection and pricing

All tests processed by certified national labs

MRO review included for all non-negative results

Choosing the correct panel is critical to meet regulatory compliance and employer policies.

TEST TYPE 5

## 5. CDL Driver Testing Options Beyond Federal Mandates

Apart from DOT-mandated urine and breath testing, trucking companies may implement additional drug and alcohol testing protocols to enhance safety or comply with state laws.

These options include random hair testing, saliva drug tests, or expanded urine panels. However, only DOT-approved urine and breath tests fulfill federal compliance for safety-sensitive positions.

AMH Nationwide supports all testing types but directs clients to use DOT-regulated protocols for federally mandated testing. Non-DOT testing can supplement but not replace these requirements.

Employers must maintain chain-of-custody and use certified collection sites from AMH’s national lab networks to ensure sample integrity and result validity.

Call (877) 731-6362 to discuss CDL driver testing options tailored to your organization’s needs.

Frequently Asked Questions

## Common Questions

The DOT urine drug test screens for marijuana metabolite (THC), cocaine metabolite, amphetamines, opioids, and PCP. These are the federally mandated five drug classes required for commercial drivers operating CMVs.

No. Hair follicle testing is not accepted for DOT-mandated drug testing of safety-sensitive trucking positions. DOT requires urine testing under 49 CFR Part 40 and breath alcohol testing for compliance.

Urine drug tests typically detect recent drug use within 1 to 3 days, depending on the substance. Hair tests detect drug use over a much longer period, up to 90 days, by analyzing drug metabolites deposited in hair shafts.

AMH routes specimens to one of five national lab networks, all certified and compliant with federal standards. Every non-negative screen is reviewed by a certified Medical Review Officer (MRO), who verifies results and addresses medical explanations.

While employers may use hair or saliva tests for non-DOT screening, federally mandated testing for CDL drivers must use DOT-regulated urine and breath tests. Non-DOT tests can supplement but not replace federal requirements.

AMH does not offer online ordering. To schedule drug and alcohol testing for truck drivers, call (877) 731-6362. AMH will provide lab orders and direct you to a certified collection site within the national lab network. Pricing varies by panel and detection window.
