4 people dead as trailer falls off bridge in Ojuelegba

Four people have been confirmed dead after a trailer carrying a container which is reported to be about 5 tonnes heavy fell from the Ojuelegba bridge and landed on vehicles, a car and a SUV below.
The incident occurred around 4:45 yesterday afternoon.
Shouldn't trailer, tanker and other heavy duty vehicles be ban from using the roads during the day to avoid unnecessary lose of lives. Some of the trailers driver also need to be enlightened about driving with care for other road users.
May the soul of the dead rest in peace. More photos from the scene after the cut
