The speed limit was 45 MPH.
Apparently, I was driving "too fast for conditions"...however, he pulled me over despite that fact that (a) I am driving a Jeep, which is designed to be able to handle such conditions, and (b) there was nobody in front of me, so I would still have plenty of time to brake if needed.
He acknowledged both of these points, but still gave me a warning.
Since it was just a warning (and therefore doesn't go on my record or have a fine), I didn't make an issue out of it (though my grandma certainly did, lol). But it's annoying. Cops should not be wasting their time pulling people over who are being safe, even if they ARE just outside of what is "legally allowed" (assuming, for the moment, that I was in fact going too fast...even my grandma doesn't think I was, and she's scared of driving, period).
Anyway, that's my rant for the day.
