Chapter 4: The Legal Requirements of Boating
Alcohol and Drugs

Texas law prohibits anyone from operating a vessel while intoxicated (BWI), that is while under the influence of alcohol or drugs. This includes operating any boat, sailboat, personal watercraft, water skis, sailboard, or similar device while intoxicated. Alcohol and drugs cause impaired balance, blurred vision, poor coordination, impaired judgment, and slower reaction time. Alcohol contributes to about one-third of all fatal boating accidents nationwide. Read more about the effects and risks of consuming alcohol.

Boaters on Texas waters should be aware of the following Texas laws.

  • Operators who have a blood alcohol concentration of 0.08 percent or greater are considered intoxicated.
  • Texas law establishes the following penalties for boating while intoxicated.
    • First conviction carries a fine of up to $2,000 and/or jail time up to 180 days.
    • Second conviction carries a fine of up to $4,000 and/or jail time up to one year.
    • Third conviction carries a fine of up to $10,000 and/or jail time of 2-10 years.
  • By operating a vessel on Texas waters, you have consented to be tested for alcohol and/or drugs if arrested by a law enforcement official. Refusal to submit to testing may result in the suspension of your vehicle driver’s license for at least 180 days.

Don't drink and boat!
