I'm a little late with this, but today is the equinox and for those of us where most roads were laid out E/W/N/S we've got the sun lined up directly along the road at dawn and dusk.

At low light angles, anything your shadow is pointing at can't see you.

Be careful out there!

Good advice. I have always tried to avoid riding when the sun is low on the horizon. I know how difficult it can be to see what's ahead of you while driving. Even flashing tail lights are sometimes difficult to pick out.

That's why I ride at night wearing all black clothes riding an all black bike with no lights. If they can't see you, they can't hit you!

This is how I take my prey, coming out of the sun like the Red Baron

Because it is incorrect. If they are blinded by the sun, why aren't there multiple crashes on every road that faces a sunrise or sunset. Motorists wouldn't be able to see any other road users or any traffic signs if they were blinded by the sun, right?

Sigh. The world isnít binary, and bicycles are usually smaller than automobiles. But even drivers need to be careful.

People *MAY* have trouble seeing. Be careful out there.

With the gap in oncoming traffic, and the long shadows pointing RIGHT at the driver in the truck, I knew he may not see me. (I had my lights on too!) Oh, my lane position? The lane.

It's gonna be a bright bright Sun-shiney day!

Going into the direction of the sun is only ONE of the problems, where not only are YOU having trouble seeing, but people behind you are also having trouble seeing.

But anytime *you* have a long shadow, your long shadow POINTS to people who may not see you.

So if your long shadow is pointing to 12 o'clock, oncoming people may not see you. Left crosses and pull outs are more likely with your back to the sun.

Similarly, if you are crossing an intersection and your long shadow points at either 9 o'clock or 3 o'clock, people in that direction may not see you.

AND, if you can see long shadows pointing AT you, even if you can't see the sun be aware that you may not see something in that long shadow.
