In the state of Texas and across the United States, the Department of Transportation (DOT) plays a crucial role in ensuring the well-being of both drivers and passengers. To uphold the highest safety standards, the DOT enforces strict drug testing regulations for folks who drive vehicles of a specific size or transport a certain number of passengers.

Why Does the Texas DOT Require Testing? 

In the transportation industry, the lives of countless individuals driving and on the roadways are at risk every day. Therefore, safety is of the highest importance. DOT drug testing is vital to maintaining a drug-free workplace for employees involved in safety-sensitive roles, such as commercial drivers, bus drivers, pilots, and train operators. Drug use impairs cognitive and motor skills, making it imperative to identify and prevent substance abuse to ensure the general public’s safety.

What Are the Types of DOT Tests? 

To receive and maintain a commercial driver’s license in Texas, you must complete drug testing at various times throughout the process of licensing, employment, and throughout the year. 

Here are the times related to DOT or CDL regulations at which you can expect to be drug tested: 

  • Pre-employment – before beginning employment and/or securing your CDL. If you need to find a location to submit a sample for drug testing, Integrity Urgent Care has 13 locations across Texas where you can walk in for testing or check in online to save your spot in line and minimize your wait. Employers must receive a negative drug test before allowing a driver with a CDL to operate their commercial vehicle or before an employee begins their safety-sensitive position. 
  • Random – Employers are subject to DOT regulations which require random drug screening of a percentage of employees throughout the year. Employees in regulated positions should expect to be randomly tested at least once yearly. Employers, we would love to partner as your DOT physicals and drug screenings provider. 
  • Reasonable suspicion or cause – If one or more trained supervisors reasonably suspect that an employee is under the influence of drugs or alcohol, drivers must submit to a test. 
  • Post-accident – If you are involved in an accident while driving a commercial vehicle or while performing your safety-sensitive job, you will likely be tested for drugs and/or alcohol or both following the accident. You may also be required to repeat testing in the days following the accident. 
  • Return to duty – If you have tested positive, refused a test, or violated regulations, you will be required to test negative before resuming driving duties. If you tested positive, you may be subject to additional testing for the year following your return to work. 
  • Bi-annual DOT physical – To maintain your CDL or regulated position, you should have a DOT-approved physical examination every two years. You may also be drug tested at the time of your physical. 

The tests themselves are quick and pain-free. Urine tests are the most common type of DOT drug test. However, you may also be subject to other testing depending on the situation. Here are a few of the types of screening tests you may encounter. 

  • Urine Testing – Urine testing is the most common method used for drug screening due to its reliability and non-invasiveness. It detects recent drug use, usually within the past few days. You can expect to provide a urine sample for screening when you visit Integrity Urgent Care for your approved Texas DOT drug test.
  • Blood Testing – In some instances where other health issues may be present, a blood test may be done as a part of your DOT physical or DOT drug test. This is a simple blood draw. 
  • Breath Alcohol Testing – While not a drug test, breath alcohol testing is often included in drug testing procedures to identify alcohol impairment. If you are involved in a motor vehicle accident while driving a commercial vehicle, you may be asked to do a breath alcohol test. 
  • Saliva Testing – Saliva tests are becoming more popular due to their ease of administration and quick results. They can detect recent drug use within hours to a couple of days.

Who Needs Texas DOT Drug Tests? 

In Texas, as in the rest of the United States, the Department of Transportation (DOT) enforces strict drug testing requirements for employees in safety-sensitive positions within the transportation industry. We have mentioned those with commercial driver’s licenses (CDL), but many other jobs are also subject to DOT testing.  

The following are some of the critical positions and industries that are subject to DOT drug testing in Texas:

  • Commercial Motor Vehicle (CMV) Drivers
  • Aviation Professionals
  • Railroad Workers
  • Maritime Workers
  • Pipeline Workers
  • Public Transit Employees
  • Hazardous Materials Transporters

It’s important to note that not all employees within these industries are subject to DOT drug testing. The regulations specifically apply to safety-sensitive positions where impairment could lead to catastrophic accidents. 

Employers in these industries are responsible for ensuring compliance with DOT drug testing regulations. They are required to establish drug testing programs that adhere to the DOT’s guidelines, including the types of tests conducted, the frequency of testing, and the consequences of positive test results. If you are an employer and need a partner for your DOT physicals and drug testing, Integrity Urgent Care is a reliable resource for all your occupational medicine needs

What Drugs Does DOT Test For? 

DOT drug screenings must test for five classes of drugs. These drugs include cannabis (including marijuana and hashish); PCP (phencyclidine); cocaine; opiates (including morphine, codeine, heroin, and methadone); and amphetamines and methamphetamines (including ecstasy, speed, MDMA, etc.).

If you take an opiate-based pain reliever or another prescription drug that might register on your drug test, communicate that thoroughly with the provider administering your test and on all forms you complete. Being prepared to provide a comprehensive medical history and a list of all medications is essential. 

Most importantly, remember that DOT drug testing aims to keep you and others safe. Be honest and test when it is asked of you.
