Width of a permanent two-lane haulage road shall not be less than how many times the width of the widest hauling truck?

Explanation:
The minimum width for a permanent two-lane haul road is set to be at least three times the width of the widest hauling truck. This ensures there’s enough clearance for the truck itself plus the mirrors and overhang, as well as a safe margin for meeting or passing another vehicle and avoiding contact with the road edge or shoulder. If it were only twice the truck width, the margins would be tight and risky; four or five times would meet the safety goal but aren’t the required minimum.
