At what speed do you turn on/off your flashers? I have been told on @ 50% of speed limit or less, off @ 75% of speed limit. I have been told on & off @ 50% of speed limit or less. Pro-drivers...
Only time we use them is when we come up on stopped or rapidly slowing traffic, from an accident or whatever, up ahead. Turn them on just long enough, to make sure those, after us slow down and don't hit us. One mountain the heavy semis will be creeping along, and wife insist on getting trapped behind them. They turn on theirs. Sometimes we d if the traffic is closing fast on us but not for long.
