I know this isn't exactly a meme but this seemed like the best place I know of to answer the question.

I was at the Vancouver convention center watching them load up a cruise ship and noticed most of the forklifts had a projection of a blue dot on the ground on the side opposite of the forkes and I don't know what they are for. I assume they are for some kind of safty but don't know what exactly. Thanks for anyone who can answer.
