Mr Hutchinson said they had serious lower body and arm injuries.
The two other passengers in the ute were transported to hospital by ambulance.
The driver of the logging truck was shaken but unharmed.
Mr Loveridge was last night in a serious condition and in intensive care, while a 29-year-old man was in a critical condition in intensive care. The two other men, aged 20 and 19, had been discharged, according to hospital reports.
Mr Loveridge is considered Hawke's Bay's top stockcar driver and was one of the country's best last summer.
He only recently recovered from a broken foot, suffered while racing for the Maulers at the Huntly Teams Champs last November. Last season he won the East Coast, Hawke's Bay, Gisborne Classic, Huntly Speedfest, Kuru Cup and Peter Barry titles.
Yesterday's crash delayed motorists for several hours as traffic came to a standstill until the road was reopened about 3.30pm.
Central Hawke's Bay Mayor Peter Butler was travelling back from a business trip in Taupo when caught behind the carnage.
"We saw the helicopter, the ambulances ... once the emergency services had cleared, a policeman told us it could be a four-hour wait and they were treating it as a potential fatal," he said.
The serious crash unit is investigating.
