For a long time, Metro Rail abided by the honor system. However, this past summer, gates and turnstiles were locked at 16 Metro subway stations to monitor riders and prevent commuters from riding for free. Audits conducted for these stations concluded that there was a 5% to 6% fare-evasion rate following this implementation. Despite efforts, it appears that many of the smaller light rail stations will remain on the honor system, as many are too small to have gates. Metro is examining plans for future stations to see how newer stations can be gated and locked. The agency also contracts approximately 400 deputies and 100 inspectors from the Los Angeles County Sheriff Department to check patrons for tickets and patrol stations and trains.
