Officers are appealing for witnesses and any dashcam footage following a crash on Thursday morning.
Police were called to Whitegate Drive in Blackpool at 10.10am following reports of a crash between a Renault Captur and a Honda CBF 125CC motorcycle, close to the health centre.
The motorcyclist, a 19-year-old man, has been taken to hospital with a serious head injury, although is described as being in a stable condition.
The driver of the Renault was uninjured.
The road remained closed for approximately four hours to facilitate collision investigation work at the scene.

“We have now opened an investigation to establish the circumstances that led to this collision, and I would ask any witnesses or anybody with dashcam or CCTV footage which could assist our enquiries to get in contact with the police.”
Anyone with information or footage is asked to email 2385@lancashire.police.uk or call 101, quoting log 0377 of June 10.
