Speed cameras?

So I’m driving from AZ to NH tomorrow with my dad, I’m wondering if there are any states that do speed cameras on the highways? My dad speeds a lot, I asked him to respect that I want him to do the speed limit in my vehicle but he just says “I go with the flow of traffic” kinda pisses me off but he’s my only option right now as he’s flying down in the morning. I’m just worried that if he was to get a photo speeding ticket it would go on my record and I drive for a living.
