New Titans tight end Delanie Walker is pledging his support for stricter laws for convicted drunk drivers. Walker recently sent a letter to lawmakers in Tennessee urging them to support House Bill 353 and Senate Bill 670, sponsored by Rep. Tony Shipley and Sen. Mae Beavers, which would require convicted drunk drivers to use an ignition interlock device. Currently, ignition interlock devices are not required for first-time DUI offenders. Walker, formerly with the 49ers, lost his aunt and uncle when an alleged drunk driver crashed into their vehicle the morning after Super Bowl XLVII in New Orleans. He has since been involved in the Mothers Against Drunk Driving program, taking part in fundraisers, while being outspoken on the topic. “I know too well the pain caused by drunk driving,’’ Walker said in a letter to lawmakers. “… I am excited to be playing for the Titans. And, can think of no better welcome to Tennessee than passage of legislation that will save lives and stop drunk driving. This game changing legislation would honor the memory of my aunt and uncle and all victims of this senseless crime while helping to protect families in Tennessee.” The mechanism requires a driver to have a legal blood-alcohol content level before the car will start. Repeat offenders are required to use the device only after they have been caught driving with a blood-alcohol level of 0.15 percent or greater, though the state’s legal limit for driving is 0.08. HB 353/SB 670 would require ignition interlock devices for any conviction resulting from a 0.08 reading. “Drunk driving doesn’t discriminate,’’ Walker said in the letter. “It doesn’t matter if you are a NFL football player or a football fan, anyone can become a victim. As one of the newest members of the Tennessee Titans, and as the nephew of Peaches and Uncle Bryan, I ask Tennessee lawmakers to pass HB 353 and SB 670 and protect families in Tennessee.”
