I'm guessing that many of the replies that say "don't drink and drive" are from poor expats who don't own even a motorcycle, let alone a car.
I explicitly said "never intoxicated" I just wanted to know, if I had a beer, and the cop smelt beer on my breath, how to avoid the obvious lengthy inconvenience after.
I appreciate the 2 helpful replies thus far, alien & quake, and find those answers helpful.
To those of you who wrongly accuse me of driving while drunk, I hope you manage to get a vehicle in the near future.
