I am a private pilot without a current medical, but with a valid
drivers license. Can I fly under the sport pilot rules, or do I need
to apply for a sport pilot certificate? I have never been denied a
medical.

We've kicked this horse a lot.
You are going to get a range of responses from yes to no. The way I
look at it, if you have a physical condition that would flunk getting a
third class medical certificate, then you should NOT be flying.
The most specious argument against my statement goes something like:
"Well, I(you/he/she/it) may be taking a disqualifying medication, but
otherwise...."
Dang it, if you are taking a medication (let's say an antihistamine)
that can degrade your skills, abilities, functions, congnition, etc., then
you damn well shouldn't be taking the risk. Or for that matter, putting the
rest of the pilots and people in the area at risk.
If that isn't the answer you wanted, I don't apologize.
I'm 68 years old and just recently passed my physical. If I didn't take
a wad of (FAA acceptable) pills every day, I would not have passed.
Well..., I may have passed AWAY.
Using the driver's license in lieu of a physical may be justified by
not wanting to incur the expense, but certainly not to thwart safety.
So, why don't you just go take the physical?
