Four Corners began as a 19th century agricultural community located at the crossroads on the Bladensburg and Colesville Roads. The community remained rural until the post-World War I building boom in suburban Montgomery County. Beginning in the late 1930s, Four Corners saw the development of Northwood Park, Woodmoor, Indian Spring Village, Indian Spring Terrace, North Hills of Sligo Park, and Fairway. These subdivisions expanded between 1945 and 1955 even as new ones, such as Northwood and Franklin Knolls, were constructed. The single-family house subdivisions that soon surrounded Four Corners had winding streets that formed an irregular grid in between major roads. Four Corners was largely developed by the late 1950s.

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.

For specific requirements, click the appropriate agency listed below in which you or your company is regulated by. Ask about our DOT Complete Compliance Package!

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.

Four Corners began as a 19th century agricultural community located at the crossroads on the Bladensburg and Colesville Roads. The community remained rural until the post-World War I building boom in suburban Montgomery County. Beginning in the late 1930s, Four Corners saw the development of Northwood Park, Woodmoor, Indian Spring Village, Indian Spring Terrace, North Hills of Sligo Park, and Fairway. These subdivisions expanded between 1945 and 1955 even as new ones, such as Northwood and Franklin Knolls, were constructed. The single-family house subdivisions that soon surrounded Four Corners had winding streets that formed an irregular grid in between major roads. Four Corners was largely developed by the late 1950s.
