Mr Myerscough came off his motorbike
A jury has retired to consider its verdict in the case of an off-duty police officer whose motorbike killed a pedestrian as she walked home.
Pc Damien Myerscough, 42, came off his motorbike before it hit Lyndsay Oldham, in Ainsworth, Bury, in April 2007.
Mr Myerscough denies causing death by dangerous driving.
Judge Elliot Knopf said if the jury could not find Mr Myerscough guilty on that charge they could look at driving without due care and attention.
Mr Myerscough's motorbike drove into a car that had turned right in front of him, Bolton Crown Court was told.
He was sent sliding into the kerb, breaking his leg, but his motorbike hit Ms Oldham, 43, who was walking down the road with two of her children.
