If you are a commercial driver who operates a vehicle for interstate business purposes, you are required to undergo Department of Transportation, or DOT, drug testing to ensure you are healthy enough to carry goods or passengers responsibly. But what exactly are the differences between a regular and a DOT drug test? Artesia Drug and Alcohol Screening in Eddy County, NM, provides accurate and timely drug tests, DOT physicals, and more and is known as a trusted resource for companies’ testing needs. Here, they explain the differences between DOT and non-DOT drug testing.

DOT Drug Testing

The Department of Transportation is quite strict about a driver’s physical condition to ensure the safety of everyone on the road. In addition to testing for street drugs with a urine sample, they will also test the function of your kidneys and for diabetes. During your appointment, you will be tested for alcohol use by way of a saliva test or a breathalyzer, and you are not allowed to consume alcohol within four hours of reporting for duty. Furthermore, the DOT completely prohibits the use of narcotics, even those prescribed by a doctor, and your drug testing professional will look for their presence in your sample.

Non-DOT Drug Testing

Although DOT and non-DOT testing screen for the same substances, they cannot be conducted at the same time. Non-DOT drug testing is usually conducted after DOT testing and may not utilize any previous samples. Additionally, the results of a non-DOT test cannot override a DOT test with a positive result. 

It’s important to work with a drug testing company that understands the difference between DOT and non-DOT testing and has the proper paperwork to ensure you start your job as quickly as possible.
