More than 5,800 people throughout the state have signed up to receive soberity checkpoint information through the text messaging feature of the Act Civilized initiative.

The state Public Safety Department launched the campaign in 2009.

The alerts are sent directly to individuals' cell phones and include checkpoint schedules, safe ride home reminders and taxi numbers.

"The goal is to encourage people to think twice about drinking and driving," James Carpenter, driector fo the South Dakota Office of Highway Safety, said in a news release.

Carpenter added that by providing people information about drunk driving enforcement acitivity, state officials hope to influence drivers to make "responsible decisions" and avoid driving drunk.

The text messages are part of a broader campaign that includes television, radio, billboard and in-store advertising designed to portray drunken driving as primitive and unacceptable behavior.
