A Melbourne couple is lucky to be alive after a learner driver with a blood alcohol level allegedly three times over the legal limit ploughed into their bedroom wall.

The 24-year-old learner driver ploughed through the bedroom wall about 2.20am in Truganina, 22 kilometres west of Melbourne's CBD.

The homeowner said he and his pregnant wife heard tyres screech and got out of bed moments before the car crashed into the front of their home, sending bricks flying.

The 24-year-old unaccompanied learner driver caused extensive damage to the home in Melbourne's western suburbs.

"We were about to go to bed and we suddenly hear a sound, a scorching sound of wheels, and by the time we could just get up from the bed and go towards the door of the bedroom, the car was already in our bedroom," Amit Saraf said.

"It was my wife and myself in the room and she was on the side where the car actually hit the wall, so we are fortunate that she's fine and I'm fine.

"I think there was a fraction of a second where we got up and the car was already in ... couldn't even understand what happened."

The couple were lucky the car did not drive any further into the home.

Mr Saraf said that when he and his wife got to the front of the house, the learner driver was struggling to get out of the car.

"So we just checked with him whether he was safe, because obviously human life is more than anything else," Mr Saraf said.

"Once I called Triple Zero, he was trying to get into the car and basically get the car out but then we said that if you do that, the structure might come down, and he came out of the car."
