Calculating the curve – The Municipal

Dec 03, 2013· This change in weather conditions would lower the critical speed of the curve to approximately 34 mph. If the same driver, who previously drove through this curve at 40 mph on a sunny day, attempted to do the same thing on a rainy day, he would find himself spinning off the roadway. This is because the rain caused the critical speed of the curve to drop to from 40 mph to 34 mph.
