A spokesman for the Welsh Ambulance Service said they were called to the crash scene at around 10.19am and sent one ambulance.
A woman was taken to Glan Clwyd Hospital in Bodelwyddan with as-yet unknown injuries.
A man aged 30 from Oldham has since been charged with dangerous driving, fail to stop for police, driving with an expired provisional licence, no insurance and drink driving.
He has been released on bail and is due to appear before Llandudno Magistrates on September 9.
Officers are appealing for any witnesses who may have seen the vehicle to contact North Wales Police on 101 quoting reference number Y114538.
