Prevention of obstruction on highway

No person shall place or cause to be placed any obstruction on the highway which hinders the free flow of traffic. The Highway Authority may order the removal of such obstruction. Where the Highway Authority is satisfied that any Highway or portion thereof, or any bridge culvert or causeway built on or across any Highway is not designed to carry vehicles of which the ladden weight exceeds such limit as may be fixed in this behalf, it may subject to such rules, as may be prescribed in that behalf, prohibit or restrict the plying of such vehicles on or over such Highway or such part of the Highway or such bridge, culvert or causeway.
