What is the blood alcohol concentration level at which a person is considered under the influence when operating a boat in California?

In California, a blood alcohol concentration (BAC) level of 0.08 percent or more is the threshold at which a person is considered to be under the influence while operating a boat. This standard aligns with the legal limit for driving a motor vehicle, emphasizing the seriousness of operating any type of vehicle, including boats, while impaired.

Operating a boat under the influence can significantly impair a person's judgment, coordination, and reaction times, which are crucial for navigating safely on the water. The law is designed to ensure the safety of not only the impaired operator but also passengers and other boaters. It is important for boaters to be aware of and comply with this legal limit to promote safety on the waterways.
