When can an officer arrest someone without a warrant according to boating laws?

An officer can arrest someone without a warrant when they witness a violation of the law. This principle is grounded in the concept of "probable cause," which allows law enforcement to take immediate action when they observe illegal activity firsthand. In the context of boating laws, if an officer sees a boater committing an infraction, such as reckless driving or operating under the influence, they can make an arrest to enforce the law and ensure the safety of all on the water.

While signs of intoxication or violations like speeding and expired registration might indicate illegal activity, the authority to arrest without a warrant is specifically triggered by witnessing the act itself. This immediate reaction helps to deter unlawful behavior and maintain public safety in boating environments.
