Australian road rules differ by state
Australia’s road rules vary more than many drivers realize. While most originate from the national Australian Road Rules, each state and territory applies its own adjustments—some subtle, others substantial enough to surprise motorists.
Hook turns only exist in one city
A hook turn requires drivers to turn right from the far-left lane, a maneuver designed to keep traffic moving around trams. Melbourne has nearly 50 of these turns in its central business district and surrounding areas. Victoria is the only state where the practice remains in active use.
New South Wales includes a similar rule under section 34 of its Road Rules, requiring drivers to turn right from the farthest left lane when facing a hook turn sign. However, the law exists only in theory—no such turns are marked on NSW roads, making the regulation effectively unused.
Crossing double lines is legal in one state—and costly elsewhere
In New South Wales, drivers may cross two continuous lines to enter a driveway or another road under section 134 of the Road Rules. The practice is common there, but it remains illegal in Queensland, Victoria, South Australia, Tasmania, and the Northern Territory.
Those states require motorists to stay left of the center line unless overtaking or leaving the road where no dividing lane exists. NSW drivers who cross double lines in other states risk fines up to $3,454.

Most states also ban U-turns at traffic lights unless a sign explicitly permits them. New South Wales, Western Australia, South Australia, and the ACT follow section 40 of the Australian Road Rules, which prohibits the maneuver without clear permission.
Victoria’s rules differ. The state does not reference section 40 in its local regulations. Instead, it only outlaws U-turns where a “No U-Turn” sign is posted. This means Victorian drivers might assume the maneuver is allowed at lights elsewhere—until they receive fines up to $2,200 in NSW.
The differences create more than confusion. They show how state-specific interpretations can turn ordinary driving into a legal hazard.
Why the differences persist
Many variations stem from historical infrastructure needs, such as Melbourne’s tram network, or local traffic conditions. They also reflect how states prioritize enforcement. A rule rarely enforced in one place may carry heavy penalties in another, forcing drivers to adapt to a fragmented system.
Some states have updated their regulations to align more closely with the national framework. Others retain older versions or create exceptions. The result is a system where even experienced drivers can unintentionally break the law.
