2024 Oklahoma BAC Limits and DUI Regulations

Drink and drive laws in Oklahoma

In Oklahoma, it’s illegal to operate a vehicle if your blood alcohol content (BAC) reaches or exceeds 0.08% (80 milligrams of alcohol per 100 milliliters of blood), and doing so may result in arrest.

Please be aware that the objective of this piece is to raise awareness of Oklahoma’s laws against drunk driving. This website does not support drinking and driving under any circumstances.

What is the Legal Alcohol Limit for Driving in Oklahoma?

In Oklahoma, the legal alcohol limits for driving are determined by the driver’s license type and age. These limits are set to ensure the safety of all road users and to discourage impaired driving. Here’s a breakdown of the legal BAC limits for each category of drivers:

  • Regular Drivers: The legal limit is 0.08% BAC. This means that having 80 milligrams of alcohol per 100 milliliters of blood is the maximum legal limit for most drivers operating a personal vehicle.
  • Commercial Drivers: For those holding a commercial driver’s license, the legal limit is lower, at 0.04% BAC. This reflects the higher standards expected of commercial vehicle operators due to the potential for greater harm in accidents involving large vehicles.
  • Minors (Under 21): Oklahoma enforces a zero-tolerance policy for underage drivers. It is illegal for minors to drive with any detectable amount of alcohol in their system, emphasizing the importance of complete sobriety for younger drivers.

Drink and Drive Penalties and Punishments in Oklahoma

In Oklahoma, the consequences of driving under the influence of alcohol are severe and can have a significant financial and legal impact on those convicted. The state has established strict penalties to deter individuals from drunk driving, emphasizing the importance of adhering to the law. Here’s a closer look at the penalties and punishments for DUI offenses in Oklahoma:


  • Financial Costs: Being arrested for drunk driving in Oklahoma can result in fines and fees exceeding $10,000.
  • Ignition Interlock Device Requirement: Oklahoma law mandates that drivers convicted of DUI, aggravated DUI, or being in actual physical control of a vehicle with a BAC of 0.15 or higher must install an ignition interlock device on every vehicle they own or is registered to them. The duration varies with the offense:
    • First-time Offenders: Required use of an interlock for 18 months.
    • Second-time Offenders: Mandatory interlock for four years if BAC exceeds 0.08.
    • Subsequent Offenses: Interlock use extends to five years for any additional DUI convictions.
  • License Revocation: Failing or refusing a breath test leads to immediate license confiscation, with the possibility of suspension for a minimum of six months upon unsuccessful appeal.
  • Sentencing: Convicted drivers face varying jail times, fines, and license revocation durations based on their offense history:
    • First Felony: 1-5 years in jail, up to $2,500 in fines, and 1-year license revocation (if previously revoked within the last 10 years).
    • Second and Subsequent Charges: 1-10 years in jail, up to $5,000 in fines, and a minimum 3-year license revocation (if revoked 2 or more times in the past 10 years).

Penalties for Minors

  • Oklahoma’s zero-tolerance law categorizes underage drinking and driving as a criminal offense, leading to license revocation and mandatory interlock for any detectable alcohol level in drivers under 21, with penalties including jail time and fines for refusal to take a test or for any first drug or alcohol offense committed by those under 18.

Social Hosts

  • The state’s Social Host Law places accountability on individuals providing a venue for underage drinking, with fines up to $500 for first-time violations. If the violation results in injury or death, the host faces felony charges, including up to five years in prison and a $2,500 fine.

It’s crucial for residents and visitors in Oklahoma to stay updated on DUI laws and penalties, as they may change. Always check the official state website for the most current information regarding drink and drive regulations and consequences.

How Can I Calculate If My Alcohol Blood Limit Is Legal in Oklahoma?

In Oklahoma, the legal blood alcohol content (BAC) limits are strictly enforced to prevent drunk driving and ensure road safety. Law enforcement officers utilize breathalyzer tests at traffic stops to quickly determine a driver’s BAC level. Understanding how to gauge your own BAC can help you make safer driving decisions. Here are two recommended methods for estimating your BAC:

1. Use a High-Quality Alcohol Breathalyzer

For those seeking a reliable way to assess their BAC, I recommend using a high-quality alcohol breathalyzer, such as the BACtrack S80, which is widely available in Oklahoma. This device offers professional-grade accuracy and is both DOT & NHTSA approved and FDA 510(k) cleared. Its precision and ease of use make it an invaluable tool for anyone who wishes to ensure they are below the legal limit before driving. Keeping a device like the BACtrack S80 in your car can be a practical step towards responsible driving, especially since it’s common for individuals to misjudge their level of impairment. As an experienced phlebologist, I can attest to the reliability of using such devices to estimate BAC levels.

2. Utilize My BAC Calculator

In collaboration with fellow phlebologists and web developers, I have created an online BAC calculator designed to help you estimate your BAC level based on various factors such as the amount and type of alcohol consumed, your weight, and the time elapsed since drinking. This tool is intended to provide you with a rough estimation of your BAC, assisting you in making informed decisions about your ability to drive safely.

It’s important to note that while both methods can offer valuable insights into your BAC level, they do not guarantee 100% accuracy. Factors like metabolism, food intake, and individual health conditions can affect BAC readings. Therefore, these tools should be used as guidelines to help you avoid driving when you might be over the legal limit of 0.08%. Always err on the side of caution and consider alternative transportation options if there’s any doubt about your sobriety.

Remember, the goal is to prevent drunk driving and ensure your safety and the safety of others on the road. Using these tools responsibly can contribute to making better decisions and adhering to Oklahoma’s DUI laws.

Ways to Avoid Driving with a High BAC in Oklahoma

Driving with a high blood alcohol concentration (BAC) not only puts you at risk of legal consequences in Oklahoma but also endangers your life and the lives of others on the road. Fortunately, there are convenient and safe alternatives to driving under the influence:

1. Utilize Rideshare Apps or Local Taxi Services

One of the most straightforward ways to avoid driving after drinking is to use rideshare apps like Uber or Lyft. These services offer a reliable and convenient option to get you home safely, with just a few taps on your smartphone. Additionally, for those who prefer traditional taxi services, local companies provide a valuable service. In Oklahoma City, you can rely on Airport Express, Inc., and in Tulsa, Tulsa Taxi Cab offers dependable rides. These services are easily accessible and eliminate the need to drive when you might be over the legal BAC limit.

2. Order a Designated Driver Service

If you’ve driven to a location and find yourself unable to safely drive back due to alcohol consumption, consider using a designated driver service. This option allows you to get both yourself and your car back home safely. In Oklahoma City, MyChauffeurDrive is a service that can provide a professional driver to take you and your vehicle home. Similarly, in Tulsa, Will-Drive offers a designated driver service that ensures you don’t have to leave your car behind. To find a designated driver service in your area, a quick Google search for “designated driver service” plus your city name will yield the necessary information.

Both of these options are effective ways to avoid driving with a high BAC in Oklahoma. They not only help you comply with the law but also contribute to the overall safety of our roads. Remember, planning ahead before you go out can make it easier to choose a safe transportation option when the time comes. Whether it’s booking a ride through a taxi app or arranging for a designated driver service, taking these steps can protect you and others from the dangers of drunk driving.

Sticking to DUI Laws in Oklahoma: Sad Statistics

In 2020, Oklahoma reported 652 road fatalities, with 27% involving drivers with a BAC of 0.08% or higher. Unlike other states where DUI and DWI terms are used interchangeably, Oklahoma distinguishes between the two: DWI for BAC levels of 0.05% to under 0.08%, and DUI for BAC levels of 0.08% and above.

To prevent DUI or DWI incidents, consider using alternative transportation such as designated driver services, Uber, or taxis if drinking. Oklahoma enforces strict DUI laws to curb impaired driving. Using an alcohol breathalyzer can help ensure you stay within legal BAC limits before driving.

It’s crucial to be aware of the dangers of drunk driving and to always opt for safer travel options after consuming alcohol. Relying on your judgement after drinking can be risky; even moderate alcohol intake can impair driving abilities.
