Sun Glare… What a difference a day makes!


James R. Schmidt, Jr., BSME, Sr. Collision Reconstruction Engineer ::::
Sun glare occurs when the sun is positioned low in the sky ahead of the direction of travel on a given roadway. It can occur in the time periods following sunrise or preceding sunset. And, it’s just what it sounds like … it’s when the sun is right in your face, thereby complicating the task of driving!

A bright sunny morning shown in the top image above, followed by an overcast morning the next day (at the same location and roughly the same time) shown in the bottom image above.
Another comparison a bit further up the roadway from one day to the next is shown below:

I once heard a local traffic reporter indicate during the morning news … “There’s sun glare in both directions.” While the sun may be shining brightly on the entire roadway, only motorists heading along a section of roadway leading toward the position of the sun have the potential to experience sun glare at any given point in time.
It’s important to keep a clean windshield, both inside and out, as well as to use your sun visor(s). A dirty windshield can exacerbate the problem that sun glare presents. Further, use of a sun visor can make all the difference between being “blinded” by the sun and being able to see what lies ahead in order to navigate your path of travel safely.
