NASCAR may use more timing zones at IMS

NASCAR [employed] additional timing zones on pit road for [Saturday's] NASCAR Xfinity race and if all [went] well, those timing zones will be used in Sunday's Brickyard 400, NASCAR confirmed to NBC Sports. There were 12 timing zones along pit road – up from six previously at Indianapolis Motor Speedway. There [was] be a timing zone about every 3.5 pit stalls on average. Those are being added to limit drivers accelerating toward their pit stall and passing cars. That became a bigger issue after NASCAR penalized Martin Truex Jr. for passing Kevin Harvick on pit road during the Sprint Cup race at Kentucky Speedway earlier this month. NASCAR experimented with the additional timing lines last weekend at New Hampshire and had no issue. NBC Sports
