If the sun is just on the horizon behind you, other drivers looking in your direction will have a difficult time seeing you. You can help enable other drivers to see you better if you...Turn your headlights on.
Airborne Refraction.
The sun is lowering slightly above the horizon as we watch. The atmosphere that surrounds our planet is what causes this intriguing occurrence. Without an atmosphere, the sun would set directly on the horizon.
A layer of air roughly 100 kilometers thick surrounds our planet. As you ascend vertically, this atmosphere becomes less dense. Also keep in mind that air has a refractive index that is slightly higher than that of the vacuum.
The sun's beams now experience a minor bending owing to refraction as they strike the top layers of the atmosphere. As the rays enter the lower atmosphere with a higher optical density, the bending keeps becoming worse.
