A car has crashed through the fence of a childcare centre in Sydney's northwest.

All the children were inside the centre on Talavera Road in Macquarie Park when the car crashed through the yard and hit a shade structure at about 1.30pm on Tuesday, a Fire and Rescue NSW spokeswoman told AAP.

Police said no children were injured and the driver, believed to be a man aged in his 40s, has been taken to hospital for observation.
