I belong to an elite group of people. I use my turn signals. True, I sometimes signal later than I should; and true I sometimes don’t turn my signal off, but I make a concerted effort to comply. If I failed to use a turn signal and someone honked at me I would be chagrined.
There are 2 million accidents a year because many people fail to use their turn signals. Which causes more accidents: distracted driving or failure to use turn signals? Over twice the amount of accidents are caused by turn signal deniers.
“A 2006 survey conducted by Response Insurance in which 57 percent of American drivers admitted not using turn signals when changing lanes. Among drivers 18 to 24, 71 percent said they don’t use their signals.”
“Turn signal technology has gone largely unchanged since the 1940s, when engineers first built a mechanism into the steering column that automatically shuts off the signal after the driver completes a turn. But that mechanical switch can fail when you merge into traffic or change lanes, which is why the Cadillac in front of you has been signaling left for the past 47 miles (76 kilometers).” – https://auto.howstuffworks.com/car-driving-safety/safety-regulatory-devices/7-bad-reasons-why-people-dont-use-their-turn-signals.htm
In most states the rear driver in a multi-car accident usually gets the blame . . . and the ticket. However, if you can prove the driver in front didn’t use their turn signal, then you have plenty of room to rebut and claim the front driver created an unavoidable driving hazard by not signaling.
Recently, I dropped my wife off at Safeway in the Proctor District and tried to turn onto North 25th. The truck in front of me stopped because the car in front of him stopped. Luckily, I kept an eye on the truck. Soon he was backing towards my Volvo grill. The car in front of him was trying to maneuver and back into a parking slot when every other car on the street had parked head-on. I laid on the horn as I shifted into reverse and looked at my review mirror. Perhaps, turn signal lights should flash when traveling in reverse . . . automatically. My all electric ZENN had a back-up buzzer to warn people.
Possibly I’m concerned about a problem that will disappear in a year or two when everyone has a self driving AI electric car. Perhaps the self-driving cars are much, much smarter than some of the clowns driving around now.
