Legwand was pulled over near downtown on Feb. 15 after a police officer clocked him going 51 mph in a 35-mph zone in his 2006 Range Rover.
Police reports said the officer noticed Legwand's eyes were bloodshot, his speech slurred and he smelled of alcohol. Legwand said he had attended a concert.
He refused a breath test and was charged with driving under the influence. He is scheduled to appear in court March 12.
Legwand signed a six-year deal for $27 million in December. He ranks fourth on the Predators in scoring. He has played in all five games since his arrest.
