Why we can't live without them
Driving a vehicle consists of tackling many tasks at one time, or multitasking. Driving the speed limit, knowing where to go, controlling the A/C or paying attention to traffic signs and signals are just a few. Don't let me forget to mention using your blinker when needed. There have been multiple times when I've seen drivers not to use their blinkers. Can you think of any?
Left Turn signal
Thank goodness this driver used his/her turn signal.
You can see in your dashboard whether or not your blinker is on or not
Road Signs can remind you, but most of the time YOU need to remember!
