DOT Changes to Part 40
On May 2, 2023, the Department of Transportation published its final rule in the Federal Register to include oral fluid testing in the DOT drug testing program. This final rule became effective June 1, 2023.
Please note that DOT oral fluid testing cannot be implemented as of yet until the Department of Health and Human Services (HHS) certifies at least two laboratories. One as a primary lab and a second lab to serve as split specimen testing.
Changes to DOT-regulated employees?
DOT-regulated safety-sensitive employees can now be subject to an oral fluid collection or urine drug testing collection for ANY DOT-regulated test and this choice is up to the employer. DOT has also authorized that Substance Abuse Professionals (SAP) evaluations may continue to be conducted remotely.
How do these changes affect DOT employers?
Employers must select what methodology they would like to use for their drug testing program (randoms' oral fluid, pre-employment urine, etc). Ensure you have a business relationship/agreement with any collections site for the services you wish to use for your drug testing program. As an employer, you must also have your Designated Employer representative available 24-7 in the event any problem collections or situations arise or to discuss any standing orders that may arise for problem collections.
What are the DOT drug testing requirements?.
In 1991, the Omnibus Transportation Employee Testing Act created the following DOT Agencies which established drug and alcohol testing regulations to ensure that aircraft, trains, trucks, and buses were operated in a safe and responsible manner. As an employer or individual operating in a "Safety Sensitive" position, it is important to understand how these regulations impact you.
49 CFR Part 40 (commonly known as Part 40) explains:
- How drug and alcohol testing is conducted
- Who is authorized to participate in the drug and alcohol testing program
- What employees must do before they may return to duty after a drug and/or alcohol violation
Each DOT Agency and the USCG have specific regulations that cover:
- The agency's prohibitions on drug and alcohol use
- Who is subject to comply with these regulations
- What type of testing is required
- When testing is required
- Consequences of non-compliance
FMCSA Drug and Alcohol Clearinghouse
The Federal Motor Carrier Safety Administration (FMCSA) amended its rule that would establish requirements for commercial driver's license employers and individuals with regard to the drug and alcohol clearing house which will take effect on January 6, 2020.
The FMCSA Clearinghouse is a secure online database that will allow employers, the FMCSA, State Driver Licensing Agencies, State Law Enforcement and individual CDL operators to access real-time important information about a CDL Driver's drug and alcohol program violations and the ultimate goal of this database is to enhance safety on our Nation's public roadways.

- United States Coast Guard (USCG) (46 CFR Parts 4,5 and 16)
- Federal Motor Carrier Safety Administration (FMCSA) (49 CFR Part 382)

The Opioid Overdose Crisis
Every day, more than 130 people in the United States die after overdosing on opioids. The misuse of and addiction to opioids,including prescription pain relievers, heroin, and synthetic opioids such as fentanyl, is a serious national crisis that affects public health as well as social and economic welfare. The Centers for Disease Control and Prevention estimates that the total "economic burden" of prescription opioid misuse alone in the United States is $78.5 billion a year, including the costs of healthcare, lost productivity, addiction treatment, and criminal justice involvement.
- Roughly 21 to 29 percent of patients prescribed opioids for chronic pain misuse them.
- Between 8 and 12 percent develop an opioid use disorder.
- An estimated 4 to 6 percent who misuse prescription opioids transition to heroin.
- About 80 percent of people who use heroin first misused prescription opioids.
- Opioid overdoses increased 30 percent from July 2016 through September 2017 in 52 areas in 45 states.
- The Midwestern region saw opioid overdoses increase 70 percent from July 2016 through September 2017.
- Opioid overdoses in large cities increased by 54 percent in 16 states.
In the late 1990s, pharmaceutical companies reassured the medical community that patients would not become addicted to prescription opioid pain relievers, and healthcare providers began to prescribe them at greater rates. This subsequently led to widespread diversion and misuse of these medications before it became clear that these medications could indeed be highly addictive.3,4 Opioid overdose rates began to increase. In 2017, more than 47,000 Americans died as a result of an opioid overdose, including prescription opioids, heroin, and illicitly manufactured fentanyl, a powerful synthetic opioid.1That same year, an estimated 1.7 million people in the United States suffered from substance use disorders related to prescription opioid pain relievers, and 652,000 suffered from a heroin use disorder (not mutually exclusive)

What is reasonable suspicion DOT drug testing in Grand Terrace, CA ?
Safety sensitive individuals and employees are required to submit to any test (whether it is a drug test, alcohol test or both) that a supervisor requests based on reasonable suspicion. Reasonable suspicion means that one or more trained supervisors reasonably believes or suspects that you are under the influence of drugs or alcohol. Supervisors cannot require testing based on a hunch or guess alone; their suspicion must be based on observations concerning your appearance, behavior, speech and smell that are usually associated with drug or alcohol use

If you have violated the prohibited drug & alcohol testing rules, you are required to take a return to duty drug and/or alcohol test before being allowed to return to a safety-sensitive function for any DOT regulated employer.

Return-to-duty tests must be conducted under direct observation.
What is DOT post accident drug testing Grand Terrace, CA ?
If you are involved in an event (accident, crash, etc.) meeting certain criteria of the DOT agency, a post-accident drug test will be required. In most cases you will then have to take a drug and alcohol test if you are involved in a qualifying crash. Each DOT agency may have specific rules with regards to what is a post-accident test, for example, the FRA requires a blood specimen for drug testing and an alcohol test.
If you are involved in a qualifying accident, you are required to remain available for this testing and are not permitted to refuse testing.
Remember: Safety-sensitive employees are obligated by law to submit to and cooperate in drug & alcohol testing mandated by DOT regulations.
What is DOT follow up drug testing Grand Terrace, CA ?
DOT follow up testing occurs when an individual has violated the drug and alcohol testing rules. The amount of follow-up testing you receive is determined by a Substance Abuse Professional (SAP) and may continue for up to 5 years. This means the SAP will determine how many times you will be tested (at least 6 times in the first year), for how long, and for what substance (i.e. drugs, alcohol, or both). Your employer is responsible for ensuring that follow-up testing is conducted and completed. Follow up testing is in addition to all other DOT required testing and all follow-up tests will be observed.

Local Area Info: Grand Terrace, California
Grand Terrace is a city in San Bernardino County, California, United States. The population was 12,040 at the 2010 census, up from 11,626 at the 2000 census. Grand Terrace is located between Highgrove and Colton, along the 215 and Aqua Mansa industrial corridors. The city is situated between two mountain ridges: Blue Mountain to the east and the La Loma Hills to the west.
Grand Terrace's roots go back to Mexican land grants dating from the period between 1830 and 1840. Mormon settlers came shortly after, arriving in the San Bernardino Valley, during the 1850s. According to the Riverside Press, in 1876, there were nine buildings in the Terrace-Colton area. Originally, the area was simply referred to as "the Terrace", but the word "Grand" was added around 1898 due to the beautiful views which surround the city. In 1905, Seventh-day Adventists, whose medical university is now located in nearby Loma Linda, settled in the area. Grand Terrace, at the time known as "South Colton", experienced continued growth and development during the Southern California suburbia and sunbelt periods in the late half of the 20th century.
The development of Grand Terrace, or East Riverside, as the Grand Terrace-Highgrove area was called, became a reality with the construction of the Gage Canal. This 22-1/2-mile canal, built at a cost of 2 million dollars, brought water from the Santa Ana River marshlands below The Terrace. With plenty of irrigation water, Grand Terrace rapidly became an agricultural community featuring fine, quality citrus. However, the severe "freeze" of 1913 destroyed many groves. Walnuts, a hardier tree, were planted as replacements along with peaches as a quick-profit crop.
