12 penalty points ≠ ban

Were you aware that you might still be over the limit when you set out?

The thought didn't even enter my mind. Had I finished drinking later/drank more then he'd have had to wait for me to get the bus in to town.

How do you feel about it? Would you feel differently if you'd been caught by a random stop and test, rather than another's error?

I feel lucky (now, but not at the time), it could easily have been so much worse. There but for the grace on Tynan etc etc

Do I think my driving was impaired in any way, No. The other legally sober drivers driving skills were clearly worse than mine.
