the sun in their eyes is no excuse
I do wonder if it's something that'd hold water in a court of law as a mitigating factor though. I mean, is sneezing an excuse for rear ending someone?
I'm not suggesting it's not the driver's fault here btw. They are in control of the vehicle, it's they that make they turn. You can't lay bottom line fault with anyone else....BUT in a court of law or insurance claim etc, a justifiable excuse could (and maybe does) limit the degree of culpability perhaps??
In the case where all road users are sharing the same conditions (e.g. wet roads, the effect of the sun, etc) I wonder if, legally, there is not a duty of care sought of thing, or a requirement for prudence, placed on everyone requiring them to exercise a greater degree of caution than normal. I guess if there was, and it could be shown that a road user was negligent of exercising that, then there could be contributory negligence....
...I'm musing btw, thinking out loud.
