Snowplow operators should take special care when clearing snow at highway/railway crossings to protect safety. Operators should stop at least 5 meters from the tracks, look and listen for trains, and only cross when it is safe to do so with enough room on the other side. Piling snow at crossings can reduce visibility and should be avoided, and salt or chemicals should never be dumped directly on or near tracks as it can cause signal issues. Maintenance work near tracks also requires railway permission for safety.
