BAC Calculator & Alcohol Chart
For purposes of this guide, “one drink” is equal to 1.25 oz. of 80 proof liquor, 12 oz. of regular beer, or 5 oz. of table wine. The State of Texas has set a .08% Blood Alcohol Concentration (BAC) as the legal limit for Driving While Intoxicated. For commercial drivers, a BAC of .04% can result in a DWI or DUI conviction anywhere in the country.

Alcohol affects individuals differently. Your blood alcohol level may be affected by your age, gender, physical condition, amount of food consumed and any drugs or medication you are currently taking. In addition, different drinks may contain different amounts of alcohol, so it’s important to know how much and the concentration of alcohol you consume.
IMPAIRMENT BEGINS WITH YOUR FIRST DRINK. FOR SAFETY’S SAKE, NEVER DRIVE AFTER DRINKING!

Testimonials
Tad and Amber are literally top of the game. When I need results, they are the only people I trust. Quality of service, knowledge and professionalism throughout. Don't gamble with a lawyer on any legal issue, you only want to bet on the best!
Thank you Tad Nelson for standing up for me and what is right, Tad Nelson is obviously well known and respected through out the court system as he spoke with authority and precisely to the assistant DA resulting in the dismissal of my case before the case went to trial. Thank you again. if you want it done call Tad Nelson
I hired them a while back for a DWI out in Harris County, they're good and if you need help with any kind of legal matter, give em a call. For a lawyer, Tad has a great personality so working with him should be easier than working with other lawyers.
He is the one lawyer that I can call and put my trust into. We’ve used him a couple of times, once for a family matter and another time for a troubled relative. He’ll help, tell you the truth with no sugar-coating, and will work for his salt. He’s a good guy and when you go to their office, they make you feel at home, like you’re part of the team. Good lawyers and great folks.
I've had the pleasure of working with Tad personally as a technology consultant for him in the past. We've eaten lunch and dinner together. I know that Tad is very dedicated to his clients and cares for them off the clock. He's definitely the lawyer you want on your side.
