While out walking early these mornings I meet quite a lot of traffic with their lights on full beam .Some would dip their lights but most don't when meeting .It don't really bother me as there is quite a wide hard shoulder but was just wondering is there any rules on this .Prob gives the cyclist an equal problem.
The standard rule is to dip your headlights when meeting another vehicle.
I learned to drive over forty years ago - the rule was followed by everyone.
Now, loads of people have fog lights on day and night, and full beams wherever they go - there is just a lack of consideration in modern drivers - but that is a reflection of socetiy as a whole.
I still dip my lights when meeting pedestrians and cyclists although I don't think there is a rule to cover it and that is the problem these days. Unless there is a rule people just do what suits them, courtesy seems to be on the way out.
A-H - I'm not sure if high-beams are always on, or that headlights have wider/higher angles than they used to? Equally those xxeon lamps in nice German saloons blind just about everyone but the driver...
