Emergency services rushed to a nasty car rollover in Perth’s northern suburbs early Friday morning.

St John WA paramedics and Department of Fire and Emergency Services were called to the busy intersection of Main Street and Royal Street — near Hutton Street — in Osborne Park around 5am after two vehicles collided, causing one to roll onto its roof.

A woman in her 40s was taken to Royal Perth Hospital for treatment of non life threatening injuries.

Main Street southbound was impacted at the Royal Street and Hutton Street intersection, with road closures put in place as emergency crews cleared the wreckage.

Main Roads WA said the scene had been cleared at 6.45am, but motorists are urged to expect delays as traffic in the area remains heavy.
