Jul 17, 2025 | Drug Testing, Employer Solutions

As the manager or business owner, your goal is to create a safe and productive workplace. Alcohol and drug testing are an important part of achieving that goal. You need to implement drug and alcohol testing policies for your employees.  

The various alcohol and drug testing regulations and methods can be complex if it is your first time navigating them. We want to help you understand the distinct types of drug and alcohol tests and the regulations governing them. We will focus on workplace alcohol testing.  

Understanding Why Workplace Alcohol and Drug Testing is Conducted 

Why would you need alcohol and drug testing in the workplace? Most employers conduct alcohol testing to ensure the safety of the entire staff. This is especially true in industries where working while under the influence could have severe consequences, such as operating machinery, driving trucks, or operating construction equipment. 

Depending on your industry, the Department of Transportation (DOT) might have regulatory requirements that you must maintain compliance with to protect yourself from fines and other punishments. You might have other reasons for testing, including reasonable suspicion or post-accident situations. 

Types of Workplace Alcohol Tests

 

There are a variety of methods you can use to test alcohol and drug consumption in the workplace.  Breath Alcohol Testing is a common method that offers certified breathalyzer screening with instant results. It measures the impairment at the time of testing. It is also offered as a Federal DOT Breath Alcohol Testing service. 

Navigating Key Regulations

Department of Transportation (DOT) regulations, specifically Part 40,  outline the DOT drug testing policies for employers in safety-sensitive industries. The types of alcohol and drug testing required by DOT include: 

  • Pre-employment 
  • Randomized 
  • For cause (reasonable suspicion) 
  • Post-accident testing 

DOT random testing is meant to be a deterrent to on-the-job drinking and misusing drugs. You must conduct DOT-required alcohol and drug testing according to protocols and trained collectors. This includes the DOT Breath Alcohol Tests and reports the results according to those same rules. DOT regulations detail what substances are tested for and how often you should be tested. You must remain in compliance with state and federal DOT drug testing regulations or face stiff consequences for your company.  

Developing a Workplace Alcohol and Drug Testing Policy

A proper drug testing program requires a mix of testing steps and cooperating policies to mitigate any risks in the program. A good and effective drug-free workplace policy needs to be clear. There are policy creation services available to help employers develop, implement, and manage these policies. 

Key elements of an effective alcohol and drug testing policy include: 

  • Lists forbidden substances and use  
  • Who is subject to the policy 
  • Testing procedures 
  • Consequences if someone refuses a drug test 
  • Outlines the use and confidentiality of the results 

 When crafting a policy, you need to consider the random drug screen policy and how you intend to handle reasonable suspicion.  

Choosing the Right Approach 

Some factors to consider when selecting testing methods and building your program are: 

  • The specific goal of the testing, such as detecting current impairment vs. past use. 
  • Breath tests measure current impairment. 
  • Regulatory requirements, including DOT mandates, specify types and procedures. 
  • The need for rapid results 
  • Level of accuracy and reliability needed 

You want to find reliable and accurate drug and alcohol testing services. Finding SAMHSA-certified labs and accredited laboratories to ensure quality in lab-based drug and alcohol testing, like ETG, is important.
