Reckless endangerment was an offense that Starfleet officers could be charged with. It involved needlessly and carelessly exposing someone to potential harm.
In 2375, Tom Paris was found guilty of insubordination, unauthorized use of a spacecraft, reckless endangerment, and conduct unbecoming an officer, offenses for which he was sentenced to thirty days in USS Voyager's brig. (VOY: "Thirty Days")
