However, NASCAR is expected to revise its policy on in-car radio communications, including a possible ban on drivers communicating with other drivers over their in-car radios for at least restrictor-plate events in 2012.

The sanctioning body is reviewing its current policy, which does allow driver-to-driver radio contact, a series spokesman said, and expects to have a revised policy in place in 2012.

The practice was used heavily during the restrictor-plate races as drivers worked in two-car tandems. The drivers would use one spotter and be able to communicate with each other.

Because the cars were hooked up so close together, one spotter could more easily and safely guide both cars. The driver doing the pushing would then know immediately when the driver in front was going to slow or change lanes.

NASCAR is expected to make other rule changes in hopes of getting rid of the two-car drafts at Daytona and Talladega. Smaller spoilers and different cooling systems are the most likely changes.
