REMEMBER: While this chart is a good general guideline, every individual reacts differently to alcohol. As our Palm Beach and Broward County DUI defense attorneys know, the chart doesn't take into account your individual body composition, your use of medications (which can affect the ways in which your body reacts to alcohol), your mood changes, or your personal metabolism rate. Therefore, your blood alcohol level may in fact be slightly higher or slightly lower than the chart indicates for the number of drinks you consume in a given time period.


For reference, our Palm Beach and Broward County DUI lawyers at the Law Offices of Leifert & Leifert know it’s a good idea to keep in mind that your body processes alcohol at a relatively constant rate of 0.5 oz. per hour. Therefore, the faster you drink, the higher your blood alcohol level will be, as your body’s alcohol processing rate not not be able to catch up to the rate at which you’re drinking. (Note that the body’s ability to process alcohol quickly tends to diminish with age.)


The estimates provided in the BAC Calculator above and elsewhere on this page are provided for educational purposes only, are not meant to demonstrate any fact, and should not be used as a basis for making a decision about drinking and driving. Do not drink and drive!

In the event that you do drink and drive and you are arrested for and/or charged with DUI, remember that the time to contact an experienced DUI defense attorney is not once your trial date is nearing; you should contact us for a free consultation immediately after being released from jail after being arrested for DUI. As our Palm Beach and Broward County DUI defense lawyers know, you can legally drive for the first ten days following your arrest. Your traffic citation for DUI states that unless your license was already suspended prior to your arrest, “this citation shall serve as a temporary driver’s license and will expire on midnight on the tenth day following the date of your arrest.” The “10 day” clock begins ticking on the day of your arrest, not the day of your release from jail (which, depending on when your DUI arrest takes place, could be the following day).


Losing your license can be a serious inconvenience; it can make it impossible for you to commute to work, to go grocery shopping, to pick your child up from school, etc. You must take action within the first ten (10) days following your arrest in order to protect your ability to obtain a temporary driver’s license and exercise a challenge to the suspension of your driver’s license. To get this critical process started, call us at 1-88-5-DEFEND (1-888-533-3363). Our Palm Beach and Broward County DUI defense lawyers at the Law Offices of Leifert & Leifert look forward to assisting you during this difficult time.

    Doug is great! He is professional, fair and follows through. He took care of my case quickly and thoroughly. I was at ease throughout the entire process. My case was dismissed, no points, no traffic school and his fee was very reasonable!
