Germany on an Irish Licence — Side Switch & the Limit-Free Autobahn

Driving in Germany on an Irish licence is paperwork-free — your EU licence is valid as-is, no International Driving Permit needed — so the real preparation is mental, and it comes in two parts.

The first is the side of the road. Ireland drives on the left; Germany drives on the right, and your rental will be left-hand drive with the gearstick on your right. Coming from Ireland this is the single biggest change, and the danger window is your first hour: pulling out of a service station, joining a roundabout that now flows anticlockwise, or a reflex glance the wrong way at a junction. Don’t make your first German drive a sprint onto a busy Autobahn — take twenty quiet minutes first and consciously place the car on the right.

The second is the Autobahn itself, which behaves unlike any road in Ireland. Many stretches have no general speed limit, only an advisory 130 km/h, and in the left lane cars can be closing at 200 km/h or more. The rule that keeps you safe is lane discipline: stay in the right-hand lane and treat the left strictly as an overtaking lane, pulling out only when you’ve checked your mirror far enough back to be sure nothing is bearing down on you. Undertaking is illegal, and tailgating to push you over is a real (if unwelcome) habit. Where signs do impose limits — roadworks, urban approaches, weather — they’re enforced firmly.

Off the motorway, limits are 50 km/h in towns and 100 on rural roads, with cameras widespread; a minor speeding fine can be as low as EUR 20–30, but they escalate quickly. The alcohol limit matches Ireland at 0.05 BAC (zero for drivers under 21 or in their first two years). You must carry a warning triangle, reflective vest and first-aid kit — all standard in a rental.

One more thing worth checking before a city trip: most large German cities have low-emission Umweltzone zones requiring a windscreen sticker. Fuel is around $1.95 a litre and 112 is the general emergency line.
