Driving in Australia vs. USA: Key Differences You Should Know

  • Feb 04, 2025

Let’s be real: driving in a new country can feel like stepping into an alternate universe. Suddenly, everything you thought you knew about the road seems up for debate. If you’re heading to Australia from the USA (or vice versa), you’re in for some surprises. The rules, road signs, and even the way you hold the wheel are enough to make any traveler do a double-take. But don’t worry—we’ve broken it all down to make your journey as smooth as a freshly paved highway.

Here are some of the major differences between driving in Australia and the USA that you need to know.

Which Side of the Road? The Left vs. Right Debate

One of the first things you’ll notice in Australia is that they drive on the left side of the road. If you're used to driving on the right in the USA, this flip can feel awkward at first. The driver’s seat is also on the right side of the car, so even your muscle memory might need some retraining.

Miles vs. Kilometers

In the USA, speed is measured in miles per hour (mph). Australia, like most of the world, uses kilometers per hour (km/h). That means road signs and speedometers look completely different.

For reference:

  • 60 mph = ~97 km/h

  • 100 km/h = ~62 mph

Australia takes speeding very seriously, with cameras and fines to match. So, if you’re a lead-footed American, double-check those speed conversions.

Highways vs. The Outback

American highways are built for long, fast travel, with plenty of lanes and rest stops. In Australia, while cities like Sydney and Melbourne have well-developed roads, the rural areas (aka the Outback) are a different story. You can expect to encounter narrow, unpaved roads, fewer gas stations, and wildlife that loves to wander onto the asphalt.

Fun Fact: Kangaroos are a common sight on Australian roads. Always stay alert, especially during dusk and dawn.

Traffic Rules

Australian traffic laws are strict, and enforcement is robust. Drunk driving laws, for example, allow a maximum Blood Alcohol Content (BAC) of 0.05%, which is lower than the 0.08% limit in most US states.

Roundabouts are another staple of Australian driving. While Americans might encounter the occasional traffic circle, Aussies encounter them on the daily. Need a refresher on the DMV road signs and traffic rules? Check out the DMV Permit Practice Test and its resources.

Fuel Prices and Distances

Fuel in Australia is priced by the liter, not the gallon, and it’s often more expensive than in the USA. Road trips in Australia can also feel longer because towns and cities are farther apart. Planning your stops and carrying extra water is a must, especially if you’re driving in remote areas.

Tolls and Fees

Both countries have toll roads, but Australia leans heavily on electronic systems. You will need an electronic tag or a pass to pay for tolls, as many roads don’t offer cash payment options. In the USA, you can still find toll booths in many places, but electronic tolling is becoming more common.

Parking

Parking rules are strictly enforced in Australia. Why? Because their road signs can be quite complicated, with time limits, restrictions, and even specific days listed. Meanwhile, with plenty of large parking lots, American parking tends to be easier to maneuver. Also, if you’re in a major Australian city, factor in high parking costs and limited availability.

Final Thoughts

From the sweeping landscapes of the Outback to the iconic stretches of Route 66, Australia and the USA offer unforgettable road trip experiences. Driving in both countries might feel worlds apart at first and might be a little nerve-wracking, but it’s all part of the adventure. So, what must you do? Just stay alert, adapt to the rules, and enjoy the scenery. Happy travels!
