(Salem, OR) -- Police agencies across Oregon will be taking part in the Click It or Ticket campaign. It's an effort to increase seat belt use. Nationwide, 90-percent of drivers and passengers use seat belts. Of people age 18 to 34 who were killed in crashes, 60-percent weren't wearing seat belts. Police agencies use federal grant money to increase patrols. Click It or Ticket continues through Sunday June 5th.
