How does the addition of sand to snow removal measures assist drivers?

The inclusion of sand in snow removal techniques primarily enhances drivers' safety by improving traction on icy surfaces. When snow and ice accumulate on roads, they can create dangerously slick conditions that increase the likelihood of vehicles skidding or losing control. Sand, when spread onto these surfaces, provides an abrasive texture that helps tires grip, thereby allowing vehicles to maneuver more effectively. This reduction in slipping is crucial in preventing accidents, particularly on inclines, turns, or intersections where control is paramount.

While other measures, such as salt or chemical agents, are often used to melt snow and ice, sand does not contribute to melting but rather focuses on improving driveability. This primary function underscores its value in winter road maintenance and enhances overall road safety for all drivers.
