Sandra Bullock and her husband were unhurt after a head-on crash with a drunken driver in Massachusetts, police said on Saturday.

The actress and her husband, Jesse James of TV's Monster Garage, were being driven in a sport-utility vehicle when a station wagon crossed the centre line and hit them, said Gloucester police Lieutenant Jerry Cook.

Both vehicles were wrecked, but no-one was hurt. The vehicles were travelling at no more than 32 km/h, Cook said.

The other car was driven by Lucille Gatchell, who registered a blood-alcohol level of 0.20 per cent, more than twice the legal limit of 0.08 per cent, Cook said.

Bullock, 43, was "gracious" and concerned about whether Gatchell was OK, Cook said.
