SURFACE CONTAMINANTS, CHAPTER 7

This chapter reviews research on how various surface contaminants can adversely affect highway safety, mainly through a very drastic reduction in traction, and the steps drivers can take to allow for this. The bulk of the chapter is concerned with ice and snow which provides the most hostile and least-forgiving environment a driver is likely to encounter. Even with the best traction aids, such as studded tires, snow tires and chains, the total traction available to propel and stop a vehicle and perform turning maneuvers is much less than even a relatively poor quality rain-slick highway. The chapter also touches on the reduced traction caused by mud and spilled diesel fuel. The latter is a rare occurrence. However, its very hazardous nature (coefficients of friction as low as that of wet ice) cause it to be noted here.
