MALOLOS, Bulacan: Governor Wilhelmino Sy-Alvarado has reiterated his call fro the strict enforcement of a provincial ordinance banning three-wheeled vehicles from Mac Arthur Highway and Daang Maharlika in this province. Alvarado said some motorists are parking along the road shoulder. Illegal vendors are plying their trade and informal settlers have settled in some portion of the national highway to the detriment of other motorists and the public. He said twenty-footer trucks are parked usually at night along the roadsides of Inter City in Barangay Wakas in Bocaue, Bulacan and in Barangay Tuktukan in Guiguinto. Moreover, tricycle and motorcycle drivers continue to use the national highway in spite the prohibition.
