Signal lights are one of the best ways to communicate while driving. Everyone is taught that signaling prior to a lane change or turning is not only mandatory but necessary so that others know what you want to do. Anyone driving in the lower mainland will realize that many drivers believe signaling to be optional.
Then there is another kind of driver – the ones who forget to turn them off. Today for instance I was stuck behind some jerk on the highway with his/her left signal light on. We were in the right-hand lane so people in the middle lane were unsure what this vehicle was going to do. I was fairly sure he was going to do absolutely nothing because I had been behind him/her for a long time. The other cars would pull up, wait and see if the car was going to move and then go by quickly. It was a very annoying commute to say the least.
