PLEASE....if you are exercising before the sun is up... please wear LIGHT colors to make you visible to motorists. Better yet, buy yourself a reflective vest or belt.
Also..CYCLISTS... make sure your lamps are working well and don't need their batteries replaced. Very dim lights don't help increase your visibility until drivers are up close to you.
I KNOW it is the driver's responsibility to see you. But if you are riding, walking or cycling before dawn or after sunset... please DO YOUR PART TO MAKE YOURSELF VISIBLE.
I always wonder if it would be inappropriate to stop these people and tell them.. "I couldn't see you till I was right next to you because you are in all black". I want to do it but I'm thinking it would not be well received.
