AA= Automobile Association - provides different levels of recovery and breakdown services for an annual premium. One of many such organisations in the UK.
I am a member of the RAC (Royal Automobile Club) which for a fee of around £90 covers me and the family in whichever vehicle we are travelling in (or on!) and will recover, arrange repair and/or transport us to UK destinations. It is expensive but has to be set against the peace of mind to be gained, particularly for the wife and youngsters if they are out driving alone - but also handy if the Burger catches a puncture too!
Also in UK, you are not allowed to carry out roadside repairs on the motorway (interstate?) and must be towed off to a service area - if you do not have the cover outlined above the fee for this can exceed the £90 premium and significantly so at weekends, evenings or public holidays.
I think you have AAA = American Automobile Association - no?!
