As long as you are claiming your auto expenses using your actual expenses rather than the standard mileage rate, then you may deduct the percentage of the cost of your AAA membership as it relates to the business use of your car (Line 9 of the Schedule C).
In other words if you use your car 100% for business then you may deduct the entire cost. If you use your car 50% for business, then you may deduct 50% of the membership cost.
