The insurance covers your registration, any processing fees, as well as any items you may have purchased, such as race gear, ARC shower passes, and so on. The cost of the insurance is based on your registration checkout total: you pay $4.99 if your registration checkout total is $24.99 or less, $5.99 if your registration checkout total is between $25 and $50, and 12% if your registration checkout total is $50.01 or more.
