safe speed is the maximum speed permitted by the basic speed law and negligence doctrine. safe speed is not the same as the 85 percentile operating speed used by traffic engineers in establishing speed zones. fog, snow, or ice can create conditions where most people drive too fast, and chain reaction accidents in such conditions are examples of where large groups of drivers collided because they failed to reduce speed for the conditions. the speeds at which most people drive can only be a very rough guide to safe speed, and an illegal or negligent custom or practice is not in itself excusable. safe speed approximates the inferred design speed adjusted for environmental alterations and vehicle and person specific factors when v is the limiting factor. the solomon curve concept can create an approach-avoidance conflict within the driver who wishes neither to drive faster than is lawful and the conditions allow nor have an unsafe speed discrepancy between other vehicles on the road; it is never legal to go faster than the speed limit, and unilaterally reducing the risk of the latter can lead to a mass crash caused by the former.
