Police have released a recording of a call to police made on the night former WA treasurer Troy Buswell left a trail of destruction after crashing his ministerial car in Perth.

In the recording, the unidentified male caller describes seeing Buswell "swerving all over Roberts Road" in Subiaco, then "struggling to stand up" when he gets out of his car.

"The bloke was dolled up to the nines and he clearly couldn't stand on his own two feet," the caller tells police.

"He was driving all over the place on Roberts Road.

"He was taking up two lanes, nearly hitting everything on the side as well.

"When we pulled up behind him out the front of his premises, his whole front bumper was hanging off, the whole front end looked like it had been pretty smashed up."

On Tuesday, Buswell pleaded guilty in a Perth court to 11 traffic offences committed in the early hours of February 23.

He was fined $3,100 and disqualified from driving for 12 months.

However, because none of the offences carry a jail term, he cannot be disqualified from Parliament.

The triple-0 caller did not know it was Buswell when he made the call, but told police he and his passenger "actually joked between ourselves, we thought it looked like Troy Buswell".

He said Buswell got out of his car when he reached his home, but had to try three or four times before finally being able to unlock his front gate.

After getting back into the car, Buswell then hit the front gate while trying to drive up the driveway.

"He had his foot on the accelerator, he's basically rammed into the gate and he's just sitting there with his foot on the accelerator and the back wheel is spinning, and then he's realised that he wasn't going anywhere and he's reversed up, turned to the right and driven through the gate," the caller said.

Buswell did not attend court on Tuesday but issued a statement of apology.

"I offer no excuses for my actions, I apologise to those upon whom I have impacted and accept fully the consequences," the statement said.

After the night in question Buswell had what has been described as a breakdown and resigned from cabinet.

However, details of his driving offences did not emerge until weeks later.

Buswell, the member for Vasse, has been on leave but is due back in Parliament next week.
