The Anambra Stàte Government on Friday announced the ban on movement of fuel tankers during daytime.
It said such vehicles can only move at night within the state. The ban followed recent fatal accidents involving trucks carrying petroleum products.
A tanker carrying petrol crashed in Onitsha two weeks ago.
Its contents spilled into the drainage and caught fire, killing at least three persons and destroying shops and goods at the popular Ochanja market in the city.
Another tanker accident happened on Thursday on the Onitsha/Enugu road but the fire service responded quickly and prevented the fuel from igniting.
In a statement by the Commissioner for Information, Don Adinuba, the state government said such vehicles can only be allowed to move within the state from 8 p.m. to 5a.m.
