Driving in the UK: Essential Tips for Australian Drivers

Driving in the UK is a rite of passage for many Australians and New Zealanders looking to see more than just the London Underground. Because they drive on the left side of the road just like we do, the transition is relatively seamless, but you will need to navigate narrow country lanes, understand specific roundabout etiquette, and ensure you have a reliable data connection for GPS. To hit the ground running, simply see plans and grab an eSIM before you leave Sydney or Auckland so you can navigate out of the rental lot without a hitch.## The Basics: Licensing and Road RulesFor most Aussies and Kiwis, your standard full driver’s license is all you need to get behind the wheel in England, Scotland, Wales, and Northern Ireland. You generally do not need an International Driving Permit (IDP) as long as your license is in English and features a photo. However, always check with your specific rental car company first to ensure they don't have extra requirements.The most important thing to remember is that the UK uses miles per hour (mph) rather than kilometers per hour (km/h). This can be a bit of a head-spin at first. If the sign says 30, it means 30 miles per hour (about 48 km/h). Most modern rental cars will have both on the speedometer, but the larger numbers are usually miles.### Speed Limits and CamerasThe UK is famous for its speed cameras. Unlike some parts of Australia where cameras are hidden, UK cameras (often called 'yellow vultures' or Gatso cameras) are usually bright yellow and preceded by warning signs. The standard speed limits are: - Built-up areas: 30 mph (unless otherwise signed). - Single carriageways: 60 mph. - Dual carriageways and Motorways: 70 mph.## Navigating the Road NetworkThe UK road system is categorized by letters. Understanding these is key to planning your route through the countryside or between major hubs like London and Edinburgh.### Motorways (M-Roads)These are the equivalent of our freeways or the M1. They are multi-lane, high-speed roads. Blue signs indicate you are on a motorway. They are generally the fastest way to get from point A to point B, but they can get incredibly congested during peak hours. If you are staying in the capital before your road trip, check out our guide on the Best Areas to Stay in London for Australian Tourists to pick a spot with easy access to the major arterial roads.### A-Roads and B-RoadsA-roads are the main routes between towns (green or white signs), while B-roads are smaller, local roads. B-roads are where you’ll find the scenic views, but they are also where you'll encounter the 'hedgerows'—tall bushes lining the road that make the lanes feel incredibly narrow. If you are heading to the Scottish Highlands or the Cotswolds, expect single-track roads with 'Passing Places.' If the passing place is on your left, pull in. If it’s on your right, wait opposite it to let the oncoming car through. A quick wave of thanks is mandatory!## Staying Connected: Why You Need an eSIMNavigation is the biggest challenge for any driver in a foreign country. While many rental cars come with built-in GPS, they are often outdated or clunky to use. Most of us prefer Google Maps or Waze, but using your Australian SIM card can lead to a nasty surprise when you get home.### Avoid the Roaming TrapTelstra and Optus love to charge 'International Day Passes' which can cost $10 per day. Over a two-week road trip, that’s $140 just for the privilege of using your own data. AussieRoam provides a much smarter alternative. Our eSIMs connect to local networks like EE (which offers 5G coverage) and 3 (4G), ensuring you have a signal even when you're deep in the Lake District.Our plans are data-only, meaning you won't get a local UK phone number. However, in the age of WhatsApp, Messenger, and FaceTime, you don't really need one. You can call the rental agency or your hotel using data-based apps without any issues. Plus, you can see plans and choose exactly how much data you need, from 1GB for a quick week-long trip to 50GB for a massive 180-day European odyssey.| Feature | AussieRoam eSIM | Telstra/Optus Roaming || :--- | :--- | :--- || Network | EE (5G) / 3 (4G) | Roaming partner (variable) || Daily Cost | One-off plan fee | $5 - $10 per day || Setup | Instant digital download | Often requires SMS activation || Flexibility | Top-ups available | Fixed daily charge |### Data for the RoadHow much data do you actually need? If you are using Google Maps for several hours a day, checking TripAdvisor for lunch spots, and uploading photos of Stonehenge to Instagram, you’ll burn through data faster than you think. - Light use (GPS only): 3GB - 5GB per month. - Moderate use (Socials + GPS): 10GB - 20GB per month. - Heavy use (Streaming + Hotspotting): 50GB.We also offer daily passes if you prefer a set amount of data every 24 hours, ranging from 0.5GB to 10GB per day. If you run out while exploring a remote castle, you can simply top up through your account.## Parking and Urban DrivingQuirksParking in the UK can be a nightmare. In cities, you’ll encounter 'Pay and Display' machines, but increasingly, councils are moving toward apps. Download 'RingGo' or 'PayByPhone' before you leave; you'll need data to use them, which is where your AussieRoam eSIM comes in handy.### The Congestion Charge and ULEZIf you plan on driving into central London, be aware of the Congestion Charge and the Ultra Low Emission Zone (ULEZ). These are daily fees for driving within specific zones. Most modern rental cars are ULEZ compliant, but you still have to pay the Congestion Charge. It is all enforced by cameras, and if you don't pay by midnight the following day, the fine is hefty.### Yellow Lines- Double Yellow Lines: No parking at any time. - Single Yellow Lines: Parking is restricted at certain times (check the nearby signs). - Red Lines: These are 'Red Routes'—do not stop here even for a second to drop someone off.## Setting Up Your eSIM for the UKBefore you head to the airport, make sure to check if your phone is compatible with eSIM technology. Most iPhones from the XR onwards and modern Samsung/Google Pixel phones are good to go.### How to Install1. Purchase your plan: Pick your UK data package on AussieRoam. 2. Scan the QR code: You'll receive this via email. 3. Label your SIMs: Call your home SIM 'Primary' and your AussieRoam SIM 'Travel.' 4. Set Data to Travel: Ensure your phone uses the eSIM for cellular data. 5. Turn on Data Roaming: You must enable data roaming for the eSIM specifically (don't worry, this won't charge your home SIM if you've turned its roaming off).For more detailed steps, check our guide on how to set it up so you can be ready the moment your flight touches down at Heathrow or Gatwick.## Beyond the UKIf your road trip extends into Europe—perhaps a ferry from Dover to France—you might want to look at our EU-42 plans which cover the UK plus 41 other countries. If your adventures take you even further, like comparing the neon lights of Tokyo after the green hills of England, you might enjoy our comparison of Shinjuku vs Shibuya: Where Should You Stay in Tokyo? to plan your next leg.## The bottom lineDriving in the UK is the best way to see the country, provided you stay alert to narrow lanes and mph speed limits. By skipping the expensive home-carrier roaming and using an AussieRoam eSIM, you’ll have the reliable 5G/4G data you need for navigation and local apps without the bill shock. Just remember: keep left, watch the roundabouts, and always have your GPS ready.
