ACDA: How Keeping Your Distance Can Keep You Safe

March 4, 2026 · 3 min read

Understanding Assured Clear Distance Ahead

ACDA, or Assured Clear Distance Ahead, is a concept you may have encountered. It refers to maintaining a safe distance between your vehicle and the vehicle directly in front of you while driving. This common-sense safety principle is also enshrined in Ohio law.

Ohio Revised Code 4511.21, titled "Speed Limits – Assured Clear Distance," explicitly states:

“no person shall drive any motor vehicle, trackless trolley, or streetcar in and upon any street or highway at a greater speed than will permit the person to bring it to a stop within the assured clear distance ahead.”

This legal requirement means that drivers must always leave enough space between their vehicle and the one ahead to safely stop if necessary.

ACDA Citation and Fault

Determining Fault After an Accident

If you receive an ACDA citation after an accident, there is a high probability that you are considered at fault, either fully or partially. Drivers have a legal obligation to maintain a clear distance ahead. Failing to do so typically makes that person responsible for an accident.

However, this is not always a definitive outcome. To understand if you are at fault due to an ACDA citation, it is best to consult with an attorney immediately. An attorney can review the specifics of your accident and provide advice based on the facts of your case. Your level of fault, whether full or partial, will depend on these specific details.

Preventing an ACDA Citation

Simple Steps for Safe Driving

Fortunately, there are several straightforward actions you can take to avoid receiving an ACDA citation.

  • Ensure your vehicle undergoes regular maintenance.
  • Having up-to-date tires and brakes is crucial for situations requiring sudden stopping.
  • Practice safe driving habits, especially in hazardous conditions. If it's raining or snowing, reduce your speed and increase the distance between your vehicle and those in front of you. This extra space can be critical in sudden braking scenarios.
  • Avoid distracted driving. Texting while driving can significantly impair your reaction time, so keep your cell phone out of reach to ensure your safety and the safety of others.

These simple measures can help prevent injuries and avoid lengthy and expensive legal disputes.

When Someone Else Is Cited for ACDA

Seeking Compensation After an Accident

If you have been involved in an auto-accident and the at-fault driver received an ACDA citation, you may be eligible for compensation. This compensation can cover your injuries, property damage, and suffering. The initial step is to contact an attorney.

An attorney will compare the facts of your case with relevant laws and advise you on the appropriate next actions. If you need to speak with a personal injury attorney regarding an accident and a potential ACDA claim, consider contacting McKenzie & Snyder.
