What are the new CDL drug testing requirements?

One of the significant updates to drug testing includes the approval of oral fluid testing as an alternative to traditional urine testing. This change allows employers and testing agencies more flexibility in testing, improving the detection of drug use in real-time, and reducing time-consuming processes.

Besides, new DOT drug testing requirements still include testing like Pre-employment, Post-accident, Random, Reasonable Suspicion, Return-to-Duty, and Follow-up testing. Instead, there are several additional requirements added to each type of test. 

Now let’s dive into the details!

Pre-employment

Before hiring a new driver, employers must perform drug tests to ensure that the individual is free from illegal substances. The test must be completed before the driver begins operating a commercial vehicle. A clean pre-employment test result is a prerequisite for starting employment in any role that requires a CDL.

Key update of this testing is that employers must ensure they are testing for both traditional substances (like marijuana, cocaine, and opiates) as well as any newly included substances under DOT regulations.

Post-accident

Drivers involved in accidents that result in a fatality, bodily injury, or damage to property requiring a commercial vehicle accident report must undergo DOT drug testing. Testing must be done as soon as possible after the accident.

Specifically, drug testing is mandatory if there is any indication of alcohol or drug involvement in the accident. The testing should be completed within 2 hours of the accident if possible, but no later than 8 hours for alcohol and 32 hours for drugs.

Random

Random drug tests are conducted without prior notice to the driver. Employers must have a system to select drivers for testing at random intervals. Random testing helps deter substance abuse and ensures drivers are always compliant, regardless of their behavior. The percentage of drivers selected for random testing may vary, but it is mandatory for employers to test at least 50% of their drivers annually for drugs and 10% for alcohol.

Reasonable suspicion

Reasonable suspicion drug testing occurs when an employer believes a driver is under the influence of drugs or alcohol based on observable behavior, such as erratic driving, poor performance, or suspicious conduct. This testing is often based on the observations of a supervisor or fellow driver.

It is worth remembering that supervisors must have completed training to recognize the signs of drug or alcohol abuse before requesting a reasonable suspicion test.

Return-to-duty

If a driver has tested positive for drugs or alcohol or has violated any substance abuse policy, they must undergo return-to-duty testing. This test confirms that the driver is sober and in compliance with the DOT’s drug and alcohol policy before they are allowed to resume driving. Specifically, a negative return-to-duty test result is required before a driver can return to work. The driver may also need to complete a substance abuse program or counseling before returning.

Follow-up testing

After a driver returns to duty, follow-up testing is required to ensure ongoing compliance with the drug and alcohol policy. These tests are randomly scheduled and are typically more frequent for the first year after a driver’s return.

The follow-up testing can last up to 5 years, and the driver must comply with all random testing requirements during this time. The frequency of follow-up tests will be determined by the substance abuse professional overseeing the driver’s rehabilitation process.
