REDWOOD CITY (KCBS)— State Sen. Jerry Hill along with members of Mothers Against Drunk Driving (MADD) introduced legislation at a news conference Monday that would require all drivers convicted of DUI to install an ignition interlock device on their vehicles.

“Estimates are that if you get arrested for one DUI, you’ve probably been driving drunk 80 times before that,” Hill said at the Redwood City news conference.

“My life was changed forever when my 22-year-old daughter, Ginger, was killed in a drunk-driving crash,” Walker said.

The requirement was recently recommended by federal transportation officials.

“Ignition interlock laws have proven to be effective in 24 states across the nation,” Hill said.
