NASCAR raises caution speed for all four road courses

SONOMA, Calif. (AP) - NASCAR has increased the caution car speed

by 5 mph at all four sanctioned road course tracks.

The pit road speeds have also been increased by 5 mph at

Infineon Raceway and Watkins Glen International.

The Sprint Cup Series races this weekend on the road course at

Infineon, and the Nationwide Series is at Road America. The caution

car speed will be 45 mph at both tracks. The pit road speed is 40

mph at Infineon, and 35 mph at Road America.

The increased speeds are intended to help the engine strain

caused by elevation changes.
