TULSA - State Troopers are urging drivers to slow down and buckle up this Thanksgiving weekend.
OHP is teaming up with seven other agencies to place traffic enforcement every 20 miles along the highways.
The I-40 challenge began yesterday to kick-off one of the busiest travel days of the year, officials say.
OHP says they will also be on watch on Sunday when many families will be traveling back home.
Each state is ramping up enforcement of life-saving traffic laws.
Officials say their goal is to have zero driving fatalities this holiday weekend.
