For your own safety, and reduced risk of being blasted with sand, never follow any closer than 30 meters behind a plow truck. Never pass a plow truck as the visibility of oncoming traffic may be restricted. Plow trucks will pull over to allow motorists to pass where safe to do so.
In addition to this, eight (8) graders maintain the gravel road surfaces operating in their assigned grader operator routes. There are a number of practices utilized, as well as a number of attachments available to perform snow removal on gravel road surfaces. In response to light accumulations a grader with its blade down, 25mm above the road surface is utilized to clear the driving lanes. Response to an event with say a meter of snow may require operators to utilize a plow attachment. Once driving surfaces are passable, grader operators will begin a second round to wing back snow utilizing their side wing attachment. This pushes snow back past the shoulder and into the ditches for future events and aides in reducing drifting of snow.
For your own safety never follow any closer than 30 meters behind a grader. Never pass a grader as visibility of oncoming traffic may be restricted and at times where drifts are present the equipment may instantly change course of direction beyond the operator's control. Graders will pull over periodically and where safe to do so to allow motorists to pass.
