In Poland, you can find yourself in prison if the police catch you cycling
with a blood alcohol concentration above a mere 0.5 mg/ml.

Wither you have committed an offence or a crime, you will be sent to trial.
In practice, judges rarely send cyclists straight to prison. In most cases,
they are fined heavily (several thousand zloty) or granted probation. The
nasty catch is that, under Polish law, a judge must ban a convicted cyclist
from riding for at least half a year. Breaching this ban is often harshly
punished. If you hap- pen to be caught breaking a cycling ban - even if you
are perfectly sober - you will face up to three years in prison. In 2012,
more than two thousand people in Poland were sentenced to prison time for
breaching a court ban on cycling, and there were as many as five thousand
inmates serving prison term for the same crime - significantly more than the
number serving time for drink driving.

Perhaps harmonisation of laws will mean that we will too? Perhaps not
though since there is talk of the drunk cycling law being revoked.
