A woman has escaped serious injury after a car crashed into the front of her house in the Perth suburb of Palmyra.

The vehicle crashed into the front wall of the home in Petra Street last night.

The male driver has been taken to hospital and is expected to be interviewed by police.

It is the second time this week a car has crashed into a home.

Earlier this week, a 78-year-old pensioner was knocked out of his bed when a car crashed into his home in Belmont.

Police said the 45-year-old driver lost control of his vehicle on Keymer Street in Belmont on Sunday night and crashed into the house just before 8:00 pm.

The car hit the bedroom, knocking 78-year-old Max Taylor out of bed.

He was shaken but his injuries were not serious.

Mr Taylor said he had no idea a car had crashed into his house when he woke up on the floor of his bedroom.

"When I came out, I said to my mate who was here, 'What happened?' and he said 'there's a car in your bedroom,' and I said 'bull dust,' [because] I didn't believe it," he said.
