Except for four laps during green flag pit stops, Martin Truex Jr. has led the entire way in the Coca-Cola 600 at Charlotte-Motor Speedway.
Truex has led 196 of the first 200 laps after starting from the pole. That is a record for most laps led in the first half of the Coke 600.
The top 10 at the halfway point is Truex, Jimmie Johnson, Joey Logano, Kyle Larson, Brad Keselowski, Denny Hamlin, Carl Edwards, Kurt Busch, Kevin Harvick and Matt Kenseth.
The caution flew twice -- once on Lap 27 so teams could be given a chance to check tire wear after earlier rain and on Lap 115 for a spin by Brian Scott (who was in 24th, one lap down).
Chase Elliott, Ryan Blaney and Trevor Bayne have been issued penalties for speeding on pit road. David Ragan has been called for a restart violation and an uncontrolled tire.
