CTo keep drivers from going so slowly that they create a hazard Correct

A minimum speed sign, such as the MINIMUM SPEED 40 sign shown, sets the lowest speed allowed on that road when conditions are normal. A vehicle crawling far below the pace of traffic makes others brake hard or swerve around it, creating a hazard much like speeding does.
