Using Brine on the Highway
Spreading rock salt on the highway during or after a weather event melts snow and ice already present to improve traction. Spraying brine on the highway before a weather event is preventative maintenance. The salt will already be there to prevent snow and ice from sticking to the pavement surface so it is easier to remove.

Here is a series of four videos from TranBC that are part of the Be Truck Aware initiative. They illustrate dangerous choices made by the drivers of small vehicles when they fail to share the road properly with heavy trucks.
Driving in poor weather conditions requires choosing an appropriate speed and then continually adjusting that speed as the conditions change. The speed signs beside our roads set the maximum for driving in ideal conditions and sometimes drivers forget this. You must consider those around you as well as yourself.
