Impey crashed into three other cars, including teammate Angus Monfries’ vehicle, after a drinking session with teammates, before the fleeing the scene.
The 21-year-old left his vehicle at the scene and made his way home, and was unreachable for several hours.
Impey has been reported with driving without due care, failing to exchange particulars and failing to report the incident and will be summoned to appear at the Adelaide Magistrates Court at a later date.
The club’s leadership group will meet last on Monday to determine a sanction for the young forward.
Impey released a short video via the club website on Sunday apologising for his actions.
