I'm not sure if you have to use the AAA CDP in order for this to apply, though.
You do have to use the AAA CDP.
The USAA CDP also has this benefit of free additional drivers and waived age differential. FWIW, as long as you have a social security number then you can sign up for free (no military affiliation required).
