CONCORD, N.C. - NASCAR today ruled that the manufacturer's label on seatbelt restraints can no longer be located under the adjusting mechanism when the driver is buckled into the seat, and the seatbelt and shoulder harness are tightened.

"If the label is under the adjusting mechanism, the label must be removed or relocated in a manner that does not affect the integrity of the belt material. The date of the manufacture must remain visible on the belts at all times."

The modification goes into effect immediately for all NASCAR series.

The left lap belt in Mayfield's No. 12 car last week was partially torn follwing a crash at Dover. Reportedly the manufacturer's label on the torn belt was under the adjusting mechanism.
