Three vehicles were involved in a crash after driving into a patch of thick fog on Eccleston Hill.
Fred Birch, 43, had to be detained in Providence Hospital with facial injuries while two others required medical attention.
The vehicles were two vans and a private car.
Two crashed head-on before the third crashed into them.
Mr Birch’s condition was not classed as serious.
The patch of fog only extended about 100 yards and, amazingly, other sections of the same road were comparatively clear at the time.
