Drivers who have their turn right signal on make a right-hand turn, but don't actually turn, they just keep going straight.

 

Also, those drivers who for some reason, just don't use their turn signals at all, they just abruptly make their turn, or change lanes, without any kind of turn signal warning.

 

I am also counting those drivers who change lanes but don't turn their signal on until they are halfway in your lane.

 

I had one of those drivers just yesterday, no signal about changing lanes until she was halfway into my lane, then the signal came on.
