After the recovery of the second victim of the collapsed road accident at the quarry near Borba, operations now are focusing on searching for the missing vehicles.
The Civil Protection Authority says that the weather is hampering operations, so only slow progress is expected.
The Prime Minister, António Costa, says it is not clear who is to blame but the President of the Republic is very clear - the State is at fault for allowing vehicles to use a road that was highly dangerous and which already had been the subject of highly critical specialist reports.
The road became the local Council's responsibility in 2014, long after safety issued had been voiced and recorded. Costa seeks to blame a local Council for an avoidable accident, one where the State turned its back on a problem.
The President, Marcelo Rebelo de Sousa, considers it "obvious" that State compensation will have to be paid but the PM says that damages will be paid only if the ongoing investigation determines the State is responsible.
Three people are still missing and the location of the sunken vehicles is not yet known.
The body of victim number two, 58-year-old quarry worker João Xavier, was pulled out of the water-filled quarry on Saturday night.
The water is being pumped out while divers and remotely operated submersible cameras are being used to try and find the remaining vehicles and bodies.
