A rookie NSW Police officer killed in a head-on crash in Sydney has been given posthumous accolades before being laid to rest.
Probationary Constable Timothy Proctor, 29, died on February 3 following a four-vehicle crash at Lucas Heights in Sydney's southwest on January 31.
The young officer was confirmed as a constable while in hospital and posthumously awarded the National Police Service Medal by Commissioner Mick Fuller at his funeral on Monday.
"While this normally is a 15-year medal, with the consent of the governor-general we will award that to Tim today," Mr Fuller said.
The commissioner also awarded Const Proctor the NSW Police Medal for his "diligent and ethical service".
Const Proctor's wife, Dianne, told the congregation at All Saints Catholic Church in Liverpool she was "blessed to be his wife".
