Sec.  3.10  What are the regulations regarding operating a vessel while 
under the influence of alcohol and/or drugs?

    (a) Operating or being in actual physical control of a vessel is 
prohibited while:
    (1) Under the influence of alcohol, a drug or drugs, or any 
combination thereof, to a degree that renders the operator incapable of 
safe operation; or
    (2) The alcohol concentration in the operator's blood or breath is 
0.08 grams or more of alcohol per 100 milliliters of blood or 0.08 grams 
or more of alcohol per 210 liters of breath.
    (b) If State law that applies to operating a vessel while under the 
influence of alcohol establishes more restrictive limits of alcohol 
concentration in the operator's blood or breath, those limits apply 
rather than the limits specified in paragraph (a) of this section.
    (c) The provisions of this section also apply to an operator who is 
or has been legally entitled to use alcohol or drugs.
