It is a summary offence of being drunk in charge of a pedal cycle, there is no lower or upper limit so it would be for the officer who stops you to deem you drunk or not.
Drink drive law relating to motor vehicles is specifically about driving whilst the amount of alcohol in your system is above a legal limit hence the requirement to provide samples for analysis
Hmmmm, So it’s more of a qualitative than quantitative measure.
I could ride a bicycle home five times over the Drink Drive limit, but so long as I manage to Ride in a fashion close enough to that of a sober cyclist, and not arouse police suspicions then I’m golden… Conversely I could be a total lightweight and find myself all over the place after half a shandy, jump on the Dandy-horse and if the Po-Po don’t think I’m pedalling straight enough then I can be done…
Units consumed isn’t necessarily what earns you points, Her Majesty’s Constabularies assessment of the standard of your cycling is…
So we’re pretty much all safe then, who fancies a pint?
