The ACT tops out at 100 km/h on Canberra's parkway network, including the Tuggeranong Parkway, Majura Parkway and Monaro Highway, with most arterials at 80 or 90 km/h and a 50 km/h default on suburban streets. School zones run at 40 km/h from 8 am to 4 pm on every gazetted school day, an all-day rule stricter than the split hours used elsewhere. Camera density is among the highest in Australia relative to road length.

About speed limits in Australian Capital Territory
Canberra was planned around a network of high-standard parkways, and these carry the territory's 100 km/h maximum: the Tuggeranong Parkway along the Molonglo corridor, the Majura Parkway link between the Federal and Monaro highways completed in 2016, and rural sections of the Monaro Highway heading south. Most of the city's arterial spine, roads like Parkes Way, Adelaide Avenue and Gungahlin Drive, is posted at 80 to 90 km/h, and the default on other streets in this almost entirely urban jurisdiction is 50 km/h. Because the ACT is so compact, crossing into New South Wales changes the rules within minutes of the city centre, including different camera and demerit arrangements on the same highway.
The ACT runs one of the strictest school zone regimes in the country. The 40 km/h limit applies from 8 am to 4 pm on every gazetted school day, including pupil-free staff development days, rather than only during morning and afternoon peaks as in New South Wales or Victoria. The all-day rule was chosen deliberately so drivers never have to guess whether a zone is active: if it is a school day, the limit is 40. Zones are marked with static signage rather than flashing lights at most sites, and ACT Policing pairs regular patrols with mobile camera deployments outside schools, with fines for school zone offences roughly 50 percent higher than the standard rate.
Since February 2021 the ACT has also rolled 40 km/h limits across its city and town centres. The Civic core, Braddon, and the Woden, Belconnen, Tuggeranong and Gungahlin town centres all carry 40 km/h limits on their internal streets, reflecting heavy pedestrian activity around shops, bus interchanges and the light rail corridor. The government has flagged extending the treatment to more group centres and shopping strips over time, consistent with its Vision Zero target. Outside the urban footprint, rural roads in the territory default to 100 km/h under the Australian Road Rules, though in practice almost all signed rural sections in the ACT are posted at 80 or 90 km/h.
Enforcement leans heavily on automation. The territory operates fixed mid-block speed cameras on its major parkways, combined red-light and speed cameras at busy intersections, a point-to-point average speed system on Hindmarsh Drive, and a rotating roster of mobile camera vans whose locations are published by Access Canberra. The ACT also applies double demerit points for speeding, mobile phone, seatbelt and helmet offences during declared holiday periods aligned with New South Wales, and adds one extra point to all other traffic offences during those windows. For a small jurisdiction the camera take is substantial, with speeding penalties earning the territory north of $20 million in a recent year.
Enforcement
ACT Policing patrols the parkways and school zones while Transport Canberra and City Services runs the camera program: fixed mid-block cameras, red-light and speed intersection cameras, mobile vans with published locations, and a point-to-point system on Hindmarsh Drive. Double demerits apply during declared holiday periods, matching the New South Wales calendar that surrounds the territory.
Tolerance
No enforcement tolerance is published, and the ACT's camera network is generally regarded as tightly calibrated, with fines issued for small margins over the limit. School zone and town centre 40 km/h limits are enforced all day, and mobile van locations rotate frequently enough that regular routes cannot be assumed camera-free.
Speeding fines in Australian Capital Territory
Fines start at $325 with one demerit point for less than 15 km/h over, rising through the brackets to more than $1,800 with six points for 45 km/h or more over, where licence suspension follows. School zone offences cost roughly 50 percent more, with the lowest bracket at about $488. During declared holiday periods demerit points double for speeding offences, though the dollar amounts stay the same.
Frequently asked questions
What is the maximum speed limit in the ACT?
100 km/h, posted on the Tuggeranong Parkway, Majura Parkway and rural sections of the Monaro Highway. Most other arterials run 80 to 90 km/h, and the default on Canberra's suburban streets is 50 km/h.
When do ACT school zones apply?
From 8 am to 4 pm on every gazetted school day, including pupil-free staff development days. The all-day 40 km/h rule is stricter than the split morning and afternoon hours used in New South Wales and Victoria, so the limit applies even in the middle of the day.
Does the ACT have double demerit points?
Yes. During declared holiday periods aligned with New South Wales, demerit points double for speeding, mobile phone, seatbelt and helmet offences, and one extra point is added to all other traffic offences. Fine amounts do not change during these periods.
Where are speed cameras in Canberra?
Fixed mid-block cameras sit on major parkways, combined red-light and speed cameras cover busy intersections, a point-to-point average speed system runs on Hindmarsh Drive, and mobile camera vans rotate through sites published by Access Canberra, with school zones a standing priority.
