California law prohibits anyone from operating a vessel, water skis, or similar device while under the influence of alcohol or drugs or while addicted to any drug. Alcohol and drugs cause impaired balance, blurred vision, poor coordination, impaired judgment (you’re more inclined to take risks when drinking), and slower reaction times.
Boaters on California waters should be aware that:
- It is illegal for anyone to operate a vessel, water skis, or similar device with a blood alcohol concentration (BAC) of 0.08% or greater. A level of at least 0.05% but less than 0.08% may be used with other evidence in determining whether a person was operating under the influence.
- Restrictions are more stringent for those under the age of 21. It is illegal for anyone under 21 to operate a vessel, water ski, or similar device with a BAC of 0.01% or greater.
