Rolling Ridge HOA

I moved in, late 2017 and as of this morning my mailbox has been hit (backed into from the neighbors driveway, usually when they have guests) and broken for a second time since living here. I will attempt to fix it tonight after work but would like to completely replace it with something newer and stronger, possibly adding reflectors so it's more visible to people backing out of the neighbors driveway. Are there regulations I need to be aware of when replacing my mailbox? I don't want to get fined for fixing something someone else broke because it wasn't the right style.
