I’ve had a number of cars over the years. I currently drive a Lexus IS.
When I go inside of my car I always keep in mind that today I’ll be sharing the road with everyone and that defensive driving should be heavily involved in my commute. I have taken defensive courses to lower my car insurance premium.
By no means I’m suggesting I’m a perfect driver but rather I understand basic road safety issues.
A car’s indicator is a traffic communicator which allows for clarity. It signals where the car is intended to go. Just like a traffic stop light, you see the RED, you must STOP. You see a flashing RED, you must stop and proceed when safe to do so. You see a YELLOW, you must prepare to stop. You see a flashing yellow, you must use caution.
A car’s indicator flashes. It is alerting traffic its intention. The fact that it flashes should have us as drivers prepared rather than to ignore it, or try to beat it. At least that’s what I believe is safer for everyone.
I do get upset when someone merges without turning on their indicator. I consider such rude and obnoxious.
Of course, there is no law stating that drivers must obey indicators. We are simply told to be courteous and nothing to enforce that.
