I wish there was one simple answer.
There isn't.
The first thing I'd do is call my insurance company.
Seriously.
People spend a lot of time searching online for this and then end up calling their insurance company anyway.
The reason is simple. Every company does things a little differently.
A friend of mine took a defensive driving course because someone told him he'd get an insurance discount. He finished the course, called his insurance company, and found out they didn't even offer that discount.
He wasn't thrilled.
That's why I always tell people to ask first.
If you're thinking about taking an Arizona defensive driving school online course for insurance purposes, pick up the phone and ask three questions:
Do you offer a discount?
Which courses qualify?
How often can I take one?
That's it.
You'll probably get a better answer in five minutes than you will after reading a dozen articles.
People also mix this up with Arizona's court-approved defensive driving program for traffic tickets. Those are completely different situations.
One is about dealing with a ticket.
The other is about a possible insurance discount.
The biggest mistake people make is assuming every company follows the same rules.
They don't.
So before you sign up for anything, make one quick phone call.
It might save you money.
It might save you time.
Either way, you'll know exactly where you stand.
