Saw a first for me anyway today:
A motorbike pulled over at the kerb , rider in waterproofs with some sort of logo, no police markings or blue lights... but the indicators were flashing right left right left etc..
never seen ANY vehicles with alternating indicators as warning lights, police have alternating blues but not indicators.
So what the hell was that about - seems a stupid system if a warning - he's pulling out, no he isn't etc.
down the road, but maybe unconnected was a land rover with trailer marked up as 'Environmental Services'
