Breath Alcohol Testing Services and When You Might Need Them

Breath alcohol testing is often required during specific events or in response to safety concerns. We help you handle each situation quickly and correctly, whether testing is mandated by federal rules or requested for personal or legal reasons.

DOT Breath Alcohol Testing Events

For DOT-regulated employers, we perform breath alcohol testing for all required testing events. This includes pre-employment, random, post-accident, reasonable suspicion, and return-to-duty testing for safety-sensitive employees.

Under 49 CFR Part 40, DOT breath alcohol testing uses evidential breath testing devices to measure current blood alcohol concentration (BAC). A screening test is performed first. If the result is 0.02 or higher, a confirmation test is performed with an EBT device following specific timing and documentation rules.

We complete the three-part DOT Breath Alcohol Testing form for every DOT test, helping employers stay organized and compliant. While only the employer and their designated medical review professionals can act on results, our role is to document and report the test outcome clearly and accurately.

Post-Accident & Reasonable Suspicion Testing

When an incident occurs, timing is critical. We support post-accident breath alcohol testing and reasonable suspicion testing so employers can document current BAC levels as quickly as possible.

DOT guidance calls for post-accident alcohol testing within specific timeframes, with a two-hour target for alcohol testing whenever possible. We help employers coordinate urgent testing needs, both at our Mesquite facility and, when arranged, at on-site locations.

Court-Ordered & Legal-Related Testing

Courts, probation officers, and attorneys can rely on us for timely, documented breath alcohol screens. We follow clear chain-of-custody procedures and provide the documentation needed for court-ordered breath alcohol testing and other legal matters.

We can work with your attorney or supervising officer on scheduling and reporting requirements, within the permissions they provide.

Personal Breath Alcohol Testing

Individuals often need breath alcohol testing for personal reasons, such as confirming sobriety requirements, supporting a treatment agreement, or obtaining documentation for a legal or family matter.

We offer personal breath alcohol testing without an employer referral. You can schedule an appointment directly with us, obtain a clear printed result, and, if desired, authorize us to share that result with a named professional or agency.

Who We Serve for Breath Alcohol Testing in Mesquite

We partner with a wide range of clients in Mesquite, Dallas County, and the DFW area, from single individuals to large transportation fleets. Whether you need a one-time test or an ongoing program, we can tailor our services to fit.

FMCSA and Other DOT-Regulated Employers

We support FMCSA-regulated employers, including commercial trucking companies, bus operators, and CDL holders in safety-sensitive roles. FMCSA regulations under 49 CFR Part 382 require breath alcohol testing as part of pre-employment, random, post-accident, and other required events for drivers.

In addition to FMCSA employers, we also test for other DOT modes, including FAA, FRA, FTA, PHMSA, and USCG-regulated employers. Our breath alcohol technicians are familiar with DOT 49 CFR Part 40 compliance standards across these agencies.

Non-DOT Employers & Drug-Free Workplace Programs

Many employers who are not regulated by DOT still choose to conduct breath alcohol testing as part of a drug-free workplace policy. In Texas, non-DOT employers aren't required by state law to test, but many do so to support safety and productivity.

We provide non-DOT workplace alcohol testing, help you craft clear policies, and offer ongoing testing support so your program is consistent and fair.

Courts, Legal Professionals, and Individuals

Legal professionals and courts rely on clear, timely documentation. We provide breath alcohol testing for probation departments, attorneys, and court-ordered programs, with results reported according to your instructions.

Individuals are always welcome. You can come to us directly for personal breath alcohol testing, whether or not an employer or court is involved.

DOT Breath Alcohol Compliance: How the Process Works

For DOT-regulated employers, breath alcohol testing must follow specific steps. Our certified professionals manage this process from start to finish, so you can focus on your business while staying compliant.

Screening and Confirmation Tests

Under DOT rules, breath alcohol testing often starts with a screening test using an approved screening test device. If the screening result is 0.02 or higher, a confirmation test is required using an evidential breath testing device.

Our breath alcohol technicians manage the full procedure, including proper waiting periods between screen and confirmation, correct operation of the Lifeloc Phoenix 6.0, and clear communication with the employee during the process.

Documentation, Forms, and Chain of Custody

Every DOT breath alcohol test requires accurate paperwork. We complete the three-part DOT Breath Alcohol Testing form, maintain secure chain-of-custody procedures, and provide copies to the employer consistent with DOT rules.

This reduces the administrative burden on your team and helps you stay ready for any compliance review or audit.

Random Programs, Post-Accident Support, and Audits

We offer a DOT Random Drug and Alcohol Testing Program for employers who want help maintaining a compliant random pool. Our team manages selections, notifications, and testing logistics based on current agency testing rates, such as the FMCSA random testing program requirements.

When a post-accident event occurs, we help coordinate timely breath alcohol testing in line with DOT expectations. We also support DOT audit preparation by providing access to testing records and documentation that demonstrate your program's compliance history.

Breath Alcohol Testing FAQs

What Should I Bring to a Breath Alcohol Test?

Please bring a valid, government-issued photo ID, such as a driver's license, state ID, passport, or military ID. If you're testing for an employer or court, bring any paperwork or authorization they provided.

No fasting or special preparation is required for a breath alcohol test, but you may be asked to remove gum, candy, or anything in your mouth before testing so the results reflect your actual breath sample.

How Is Breath Alcohol Testing Different From Other Alcohol Tests?

Breath alcohol testing measures your current blood alcohol concentration at the exact time of the test, using a breathalyzer-type device. It shows whether alcohol is present in your system right now, which is why DOT regulations use breath tests for alcohol confirmation testing.

Other methods, such as EtG urine or hair alcohol testing, look for alcohol metabolites that remain in your body after drinking. These tests can indicate alcohol use over a longer period, but they don't pinpoint your present BAC in the same way a breath test does.

Is DOT Breath Alcohol Testing Different From Non-DOT Testing?

Yes. DOT breath alcohol tests must follow the strict protocols in 49 CFR Part 40. This includes specific device requirements, a two-step screen-and-confirm process for certain results, chain-of-custody rules, and detailed documentation on standardized forms.

Non-DOT breath alcohol testing is more flexible and can be adapted to your company policy, but we can still use the same high-quality equipment and certified technicians. Many employers choose to align their non-DOT testing with DOT-style procedures for consistency.
