Police have reminded revellers at the annual Summernats car festival that hoon driving and anti-social behaviour will not be tolerated after a handful of incidents.
One motorist will face court for allegedly doing burnouts and three cars were seized for hooning following day two of the four-day event in Canberra.
Most of the activity occurred where crowds gathered on Friday evening at the Braddon Fringe Festival, Kambah Pool Road and O'Connor.
About 120,000 people are expected to attend the festival, which includes lawn mower racing, a mullet haircut competition, sanctioned burnouts and performances from Daryl Braithwaite and Grinspoon.
The festival will showcase 2700 modified vehicles ranging from classics to supercharged.
Revheads will put their engines to the test at the burnout masters event and thousands of cars will be whittled down to about a dozen who will vie off for the ultimate prize of being crowned the grand champion.
The grand champion will be awarded to the best car and has several criteria, including a judging panel pick, people's choice and two driving components.
Mullet growers will be judged in a variety of categories including grubby, vintage for those silver foxes over 50, extreme, ranga and rookie for those who've had a mullet for under a year.
While the event brings in tens of millions of dollars for the local economy with 85 per cent of attendees being from interstate, it's not popular with all the locals who complain of burnout smoke and loud revving late at night.
Police have warned there are thousands of spots in the confiscation lot ready to be filled with fast cars.
