Police allege that at about 12.50am on May 4, a Ford Ranger utility collided with a light post while attempting to negotiate a roundabout in Geraldton, about 420km north of Perth, and that as a result of the crash, the light post crumpled at the base and fell across the roadway.
WA Police said in a statement it would be alleged Brockman, who was driving the car, fled the area on foot.
It would be further alleged Brockman returned to the crash site a short time later to remove the vehicle prior to police arrival, and that neither the crash or the damage to property was reported to police.
Police said Brockman had been charged with careless driving, failing to report an incident in which property was damaged, and driver failing to stop.
The 21-year-old, is due to appear before Geraldton Magistrates Court on July 5.
Brockman played 26 games for Hawthorn before being traded to West Coast at the end of last year.
The small forward was goalless across his first six games for the Eagles before being omitted for the six-point loss to Essendon two weeks ago.
Brockman has been relieved from playing duties since the car crash, and Eagles coach Adam Simpson says there's not yet a definitive timeline for his WAFL or AFL return.
"We're looking after the person at the moment, so we'll get together in the next few days," Simpson said after West Coast's 35-point win over Melbourne on Sunday.
"We've put some things in place for him to support and also to understand he's made a mistake as well.
"I reckon by mid-week we'll have real clarity about where he's at, what he needs to do.
"He's already missed two or three weeks, so we'll just see how we go with that.
"It's not the first time someone's made a mistake, so we'll just put our arms around him and at the same time he needs to be accountable."
