How many times can you use it in one year?

I don't think GSRA has any restrictions on the number of calls per year.

AAA states you can use it 4 times in one year whereas I cannot find anything on the GS site indicating how many times they will let you use it.

I used mine 3 times in one year no problem but zero the next year.
M guess is like AAA they work off how much it cost them in a year versus number of uses.
Example 4 flat tires in a year versus four long tows in a year
