An emergency has been declared on the Pacific Motorway after a fuel tanker spilt its load during a multi-vehicle crash that forced the closure of part of the M1 in both directions.
Police said the tanker overturned in Helensvale and spilt fuel in the southbound lanes about 11.50am on Saturday.
Four people were taken to Gold Coast University Hospital for treatment.
The motorway remains closed in both directions between the Gold Coast Highway (exit 62) and Smith Street (exit 66).
Just before 4.30pm, police said it could remain closed for several more hours.
Motorists planning to travel on the Pacific Motorway on the Gold Coast have been urged to postpone their trip, take an alternative route, or expect significant delays.
