Even when the horse has focused as best it can, its sight is only three-fifths that of a human. In other words, when looking at an object twenty feet away, the horse sees only as much detail as a person with twenty-twenty vision would if the object were thirty-five feet away.
The measured sight distance for this maneuver is 350 feet. The minimum recommended sight distance is 335 feet for 30 mph. This shows that there is adequate sight distance for a right-turn maneuver from the side road, 13th Street. Figure 4.11 shows the measurement that was conducted for a left-turn maneuver.
