¥Chapter 8, California State Traffic Manual:
¥ ÒSpeed limits established on the basis of the 85th percentile
conform to the consensus of those who drive highways as to
what speed is reasonable and prudent, and are not
dependant on the judgement of one or a few.Ó
¥Chapter 8, California State Traffic Manual:
(continued)
¥ ÒFurther studies have shown that establishing a speed limit at
less than the 85th percentile (Critical Speed) generally
results in an increase in accident rates.Ó
¥Washington State DOT website:
¥"people don't automatically drive
faster when the speed limit is raised, speed limit signs will not automatically decrease accident
rates nor increase safety, and highways with posted
speed limits are not necessarily safer than highways
without posted limits.
