Traffic officials are expecting a heavy volume of cars on area roadways around the Daytona International Speedway as visitors come in to see the Coke Zero race Saturday night.
It is an annual tradition during the 4th of July holiday and the high number of cars can mean tempers flare.
Florida Highway Patrol officials are urging drivers to be patient and drive carefully as traffic starts to build on the roadways.
Officials are expecting heavy delays around Interstate 4 and Interstate 95, which are the two main thoroughfares into Daytona Beach.
Traffic officials said drivers coming in from the race should use Exit 118-A and head east on State Road 44 to Interstate 95 to avoid heavy delays.
Early Saturday afternoon, the roads were clear, but race traffic was starting to build on International Speedway Boulevard, near the race track.
