85th Percentile Meaning. The 85th percentile is used extensively in decision making as it is indicative of the speed that the majority of road users are travelling at.  Use of the85th percentile speed concept is based on the theory that:  the large majority of drivers:  are reasonable and prudent, do not wan to have a crash, desire to reach their destination in the shortest possible time.  A speed at or below which 85 percent of people drive at any given location under good weather and visibility conditions may be considered as the maximum safe speed for that location.
