NASCAR to police pit road speeds with expanded timing zones for Xfinity race

NASCAR will employ additional timing zones on pit road for today’s NASCAR Xfinity race and if all goes well, those timing zones will be used in Sunday’s Brickyard 400, NASCAR confirmed to NBC Sports.

There will be 12 timing zones along pit road — up from six previously at Indianapolis Motor Speedway — for today’s Xfinity race. There will 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 issues, leading to the use of the timing lines for today’s Xfinity race.

Here is the pit road chart with all the timing lines.
