What ARIDE training is and who needs it
ARIDE stands for Advanced Roadside Impaired Driving Enforcement. It is a standardized training program for law enforcement officers who investigate suspected drunk or drugged driving. The course teaches officers how to recognize signs of impairment, conduct roadside tests, and document observations in ways that hold up in court.
ARIDE training is not mandatory in every state, but many states require or strongly encourage it for officers who work traffic enforcement, DUI task forces, or patrol units. Some departments make it a condition of promotion to detective or specialized units. The training does not certify an officer as an informed witness in all cases, but it does establish a foundation that prosecutors and defense attorneys recognize.
If you are an officer wondering whether your department requires ARIDE, check with your training coordinator or shift supervisor. If you are a defendant or attorney evaluating an officer's testimony, knowing whether the officer completed ARIDE helps you assess the weight of their observations.

The structure and length of ARIDE courses
A standard ARIDE course runs 16 hours, usually delivered over two or three days. Some departments compress it into a single intensive day, while others spread it across multiple weeks with evening sessions. The exact schedule depends on the training provider and the department's staffing needs.
The course is classroom-based and includes both lecture and hands-on practice. Officers learn the theory behind impairment detection, then practice the roadside tests (the horizontal gaze nystagmus test, the walk-and-turn test, and the one-leg stand test) on each other and on volunteer actors who simulate impairment. This practical component is what distinguishes ARIDE from a straightforward online or video-based training.
Most ARIDE instructors are certified through the International Association of Chiefs of Police (IACP) or through their state's law enforcement training academy. Certification requires the instructor to complete a train-the-trainer course and to maintain current knowledge of DUI law and testing procedures in their state.
What the course covers
ARIDE training covers the pharmacology of alcohol and common drugs, how impairment manifests in behavior and physical signs, and the legal framework for DUI stops and testing. Officers learn to recognize impairment from depressants (alcohol, benzodiazepines), stimulants (cocaine, methamphetamine), hallucinogens, and cannabis, as well as combinations of substances.
A significant portion of the course focuses on the three standardized field sobriety tests (SFSTs). Officers practice administering these tests correctly, learn what counts as a clue of impairment, and understand how many clues suggest impairment. The course also covers the limitations of these tests — for example, that medical conditions, age, and fatigue can produce false clues.
The training includes instruction on breath and blood testing devices, how they work, what can go wrong, and what documentation is required. Officers learn the chain of custody procedures, calibration requirements, and the difference between a preliminary breath test (which is roadside and less formal) and an evidentiary breath test (which is at the station and admissible in court).
Finally, ARIDE covers report writing and courtroom testimony. Officers learn how to document their observations in a way that is clear, objective, and defensible. They practice explaining their findings to a prosecutor and understand how a defense attorney might challenge their observations.
Who provides ARIDE training and where to find it
ARIDE courses are offered through state law enforcement training academies, regional training centers, and some private training organizations that are certified to teach the curriculum. The National Highway Traffic Safety Administration (NHTSA) sets the standard curriculum, but each state adapts it to reflect state law and local procedures.
To find an ARIDE course in your state, contact your state's law enforcement training academy or your department's training coordinator. Many states list upcoming courses on their academy website or through a training calendar. Some departments send officers to courses offered by neighboring states or by private providers if the state academy has a long wait list.
The cost of ARIDE training varies. State-run courses are often free or low-cost for officers employed by state or local agencies. Private courses may charge $300 to $800 per officer. Some departments budget for ARIDE as part of their annual training allocation; others require officers to pay or to attend on their own time.
How ARIDE training relates to DUI prosecution and defense
In a DUI case, the prosecution often calls the arresting officer to testify about the signs of impairment they observed. If the officer completed ARIDE, the prosecutor may mention this to establish that the officer followed a recognized protocol. Defense attorneys also know about ARIDE and may ask whether the officer completed it, because it helps them understand what the officer was trained to look for and whether they followed that training.
Completion of ARIDE does not automatically make an officer an informed witness who can testify about the cause of impairment or the reliability of testing methods. That requires additional training, often a DRE (Drug Recognition informed) course, which is a 64-hour program. However, ARIDE-trained officers can testify about the standardized field sobriety tests and their own observations of the driver's behavior and appearance.
If you are reviewing a police report or preparing for a DUI case, knowing whether the officer completed ARIDE helps you evaluate the reliability of their observations. An officer who completed ARIDE followed a standardized training; an officer who did not may have relied on less formal or less consistent methods.
Recertification and staying current
ARIDE certification does not expire in most states, but law enforcement agencies are expected to keep officers current on DUI procedures and changes in state law. Some states require officers to attend a refresher course every few years. Others leave it to the department's discretion.
DUI law and testing procedures change. New drugs emerge, court rulings affect what evidence is admissible, and testing equipment is updated. Departments that take DUI enforcement seriously often send officers to refresher trainings or to advanced courses like DRE certification to keep their skills sharp and their knowledge current.
If you are an officer, ask your training coordinator whether your department has a policy on refresher training. If you are evaluating an officer's testimony, you can ask how long ago they completed ARIDE and whether they have attended any refresher training since then.
ARIDE versus DRE and other specialized DUI training
ARIDE is the foundation course for DUI investigation. The Drug Recognition informed (DRE) program is a more advanced 64-hour course that trains officers to recognize impairment from specific drugs and drug combinations. DRE officers can testify as informed witnesses about the cause of impairment, whereas ARIDE-trained officers generally cannot.
Some departments also send officers to courses on breath testing operation, blood draw procedures, or toxicology. These are specialized trainings that build on ARIDE. An officer might complete ARIDE, then later attend a DRE course, then later attend a breath testing certification course.
The relationship between these trainings is cumulative. ARIDE is the baseline; DRE and other specialized courses add depth in specific areas. When you see an officer's credentials in a DUI case, you can ask what trainings they have completed and in what order.
Frequently Asked Questions
Is ARIDE training the same in every state?
The core curriculum is based on NHTSA standards, so the basic content is similar across states. However, each state adapts the training to reflect state DUI law, local testing procedures, and equipment used by that state's agencies. An officer trained in one state may need a brief orientation if they move to another state.
Can a police officer testify about impairment without ARIDE training?
Yes. ARIDE is not a legal requirement for an officer to testify about what they observed. However, an officer who completed ARIDE can explain that they followed a standardized protocol, which strengthens their credibility. An officer without ARIDE training can still testify, but their methods may be questioned more closely.
How long does ARIDE certification last?
ARIDE certification does not expire in most states, but officers are expected to stay current on DUI law and procedures. Some states or departments require refresher training every few years. Check with your state's training academy or your department's policy.
What is the difference between ARIDE and DRE?
ARIDE is a 16-hour foundation course on recognizing impairment and conducting roadside tests. DRE is a 64-hour advanced course that trains officers to recognize impairment from specific drugs and to testify as informed witnesses. Most DRE officers complete ARIDE first.
Can I learn about an officer who arrested me completed ARIDE?
You can ask the officer directly during discovery or at trial. You can also request the officer's training record through a public records request to the police department. The department may redact some information, but training completion is usually a matter of public record.
