Disclaimer: We try to keep the information provided here up to date. However, laws often change, as do their interpretation and application. Different jurisdictions within a state may enforce the laws in different ways. For that reason, we recommended that you seek the advice of a local attorney familiar with DUI cases in your area.

Can you plead to a lesser offense than DUI in Texas?

In Texas, it's possible for someone who's accused of driving under the influence to plea bargain for a lesser charge. When such a plea bargain is for a reckless driving charge, it's sometimes called a "wet reckless."

What is an SR-22?

An SR-22 is a form that your insurance company files that proves you meet certain coverage requirements. SR-22 are often required for driving who have been convicted of DUIs, serious traffic offense, or multiple traffic violations within a certain period of time.

Texas's Drunk Driving Laws

Texas law prohibits operating a vehicle while:

  • having a blood alcohol concentration (BAC) of .08% or more, or
  • actually impaired by alcohol or drugs.

And for underage drivers (those under 21 years old), it's illegal to drive with a BAC of .02% or more.  

How Many Drinks Does It Take to Reach the Legal Limit?

Everyone metabolizes alcohol at different rates, and there are a number of variables that affect BAC. So, the number of drinks it takes to put a person over the legal limit depends on individual characteristics and the circumstances. If you've been drinking, it's always best to let someone else drive.

(For an estimate of what your BAC might be after having a certain number of drinks, check out our BAC chart.)
