For those who are considering joining this protest, they need to realise what it may result in.

Driving too slowly in a manner that disrupts other drivers is an offence under the law of inconsiderate and careless driving. This has an unlimited fine and a penalty range of 3 to 9 points on your licence.

You may think that there would be too many other drivers involved to punish every one, but the Police would be more than happy to go through CCTV and NPR data to locate each offender and summon them to court.
