Yes and no. I'd be asking for more details like where was the sun at the time, what were the road conditions like, speed of the automobile, other passenger(s) in automobile, etc. If it's a curvy road I would think that drivers are asked to slow down for the curves? Are there any speed reduction signs on those roads (if not, then it's the township/county that looks after it fault).
As my uncle often tells me "There are many sides to the truth. One side, the other and somewhere in between is the actual truth".
