A 17-year-old boy has become the second person to be charged over a fatal crash that killed a veteran Victorian policeman on a memorial ride last year.

The teenager from New South Wales has been charged with culpable driving, causing the death of Detective Senior Sergeant Vic Kostiuk, as well as reckless conduct endangering life.

He was a passenger in the Holden Commodore that struck and killed Mr Kostiuk on the Princes Highway on September 14, 2018.

Police have previously claimed the 17-year-old boy blew into an interlock device to start the Holden Commodore that was allegedly driven by his 21-year-old friend.

The 21-year-old alleged driver, Jesse Reid, has also been charged with culpable driving over Mr Kostiuk's death and is being held in custody on remand.
