How to ask a guy to get tested..?

I just got out of an on again / off again 5 year year relationship. When he and I were off I had a flirtationship with this guy who lives a few hours from me.

He and I have been flirting more since I’m officially cut off from my relationship and I think we are getting to that place where a hookup will happen soon..

I’ve only been with one partner & want to ask this new guy to get tested.. not for any other reason than to just be safe.

How & do I ask? Any and all advice would be so helpful. Thanks in advance!
