The Critical Speed for a Horizontal Roadway Curve Critical speed used in this context is a term for the speed at which a vehicle will lose lateral control on a given roadway curve. The normally flawed procedure is to assume the highway curve radius as the critical path taken by the vehicle.

The unsupported length is the dominate factor, because the critical speed is inversely proportional to the square of the unsupported length. Using a fixed unsupported screw length, the critical speed can be varied by the selection of the screw diameter, lead and end bearing supports.
