Drunken driving arrests largely have been declining for the past five years in Naperville, according to police statistics.

The decreases, police and liquor enforcement officials say, have come despite an increase in the number of restaurants in town — from 255 to 320 — offering many more places where drinking away from home is possible.

Cultural shifts to more use of ride-sharing services and greater awareness of the dangers of driving while impaired could be leading to the change, said Detective Dan Riggs, the police department’s liquor enforcement officer.
