(15,691 posts)If the road is posted between 45 and 55 miles an hour, even the most careful driver would only slow down to around 40 mph going over a hill or around a curve.
Rule of thumb - Driver's training manual estimates 10 ft of sudden braking distance for every 5 mph of speed. That's once the driver hits the brakes, not counting the distance travelled in the 15 seconds or so it takes for the driver to react once he or she notices the hazard. At 50 mph, that's 50 ft + maybe another 20 ft to cover the response time. And only in the last 10 ft, an impact might be survivable to the pedestrian.
A 5 1/2' or so tall teen or a 3' tall toddler - it doesn't really matter if they're in the middle of the lane if the driver doesn't expect them and is going any faster than 15/20 mph.
