So are people just lazy or do they forget to use their signal lights to indicate they're turning left or right?
For the past week or so I've been paying particular attention to people turning left or right at intersections and going by my observations, I would say that more than half of the people making turns do not indicate such. Doesn't matter if it's left or right turns and traffic circles, well you can pretty much give up on mist people ever having a clue how to signal when using them.
That said, has anyone ever seen a CPS officer pulling over and giving someone a ticket for not indicating a turn? Enforcement might be the only way people will learn.
