The blood alcohol level for boating while intoxicated (BWI) is .08 percent - the same as a motor vehicle.
Boaters are reminded that alcohol reduces reaction time and ability to make quick, sound judgments in an emergency situation. Also, wind, sun, glare off the water, and water movement multiplies the effects of alcohol.
Operating a motorboat or sailboat while under the influence of alcohol (.08 alcohol level or higher), a controlled substance, or other illegal chemical is unlawful. For the purpose of BWI, "operating a motorboat" means the motorboat is powered by a motor that is running. For the purposes of BWI, "operating a sailboat" means the sailboat is either powered by a motor that is running or has sails hoisted and is underway. Operators who are impaired may be required to take tests by an enforcement officer to determine their sobriety. Anyone refusing to test will be charged a penalty.
All navigable waters in the state of Iowa will be subject to the law, except ponds and privately owned lakes.
