An 18-year-old man remains in a critical condition following a Redlands Bay crash that caused an out of control bus to career through two properties.

The man was driving a black BMW that collided with a public Transdev bus on Peel Street, near the intersection of James Street, shortly after 10am.

The initial crash caused the bus to career through a vacant block of land, plough through two fences and smash into a second house on James Street, taking the BMW with it.

It pushed the BMW into the Peel Street yard before hitting a parked car, a police spokesman said.
