Biking rules

Excerpt from "The Worktrotter's guide to Denmark"

Always observe the traffic regulations – the penalties are severe. 
Even if you aren’t stopped by the police, you will often be put in place by other people, because Danes don’t suffer fools gladly when it comes to traffic – particularly on the cycle paths.

To help prevent you getting into awkward or unpleasant situations, here are the most important rules (I have not seen them written down anywhere in English):
1.  Cyclists indicate their intention by means of hand signals:
–  Hand signal to the left: left turn
–  Hand signal to the right: right turn
–  Hand signal upwards: stopping

2.  When turning left at an intersection a cyclist may not use the turning left lane for cars, but must cycle across the intersection, stop (indicating this in advance by means of a raised hand), then ride in the desired direction when the lights turn green again.

3.  Cycling against the flow of traffic is forbidden.
