Speedway officials have imposed a ban on outdoor burning that mirrors one ordered by the town of Speedway on June 28.
The ban prohibits open burning including comfort fires or campfires and also bars the use of fireworks and charcoal and non-gas grills.
Speedway officials also are asking people to use caution with cigarettes, fluids from hot vehicle engines and other material that could start a fire in dry grass.
Tailgaters still have some options. Gas grills are allowed in camping and tailgating areas but must be at least 18 inches off the ground.
The U.S. Drought Monitor shows more than half of Indiana is experiencing an extreme drought.
