LEFTLANE
Country-neutral guides for licensed drivers crossing into left-hand traffic. Why the brain resists, what changes physically when you swap sides, and how to rehearse the moments where habit fails.
Clockwise flow, giving way to the right, which lane to pick and when to signal for each exit, the 2022 rule that gives cyclists priority on the roundabout, and what to do when you end up in the wrong lane.
Thirty-eight state highway sections went back up and every school street dropped to 30 km/h, both by 1 July 2026. Every limit in km/h and mph, the street-lights rule for urban areas, and the one-lane bridge signs.
The four numbers match England and Wales. What differs is a drink-drive limit that catches visitors at the border, and a single-track road whose legal 60 mph is nowhere near the safe speed.
Irish local rural roads dropped from 80 km/h to 60 in February 2025, across about 82,000 kilometers. Every limit in km/h and mph, how to read road class from sign color, and the second phase that is law but has not started.
Japan cut the limit on unmarked residential roads from 60 km/h to 30 km/h, across roughly 70 percent of its general roads. Every limit in km/h and mph, the visual test that tells you which road you are on, and what it costs to get it wrong.
The first left-side drive feels wrong because your habits are doing their job - for the country you left. Why the quiet moments catch people out, why right turns and roundabouts feel backwards, and how to make the first drive calmer.
A short habit reminder for the rental lot - rental-lot prep, slow pull-away, right turns, clockwise roundabouts, and the post-turn reset. Printable PDF, US Letter and A4 friendly.
Single-track choreography in the Highlands, clockwise roundabouts, Scotland's lower drink-drive limit, and the first ten minutes after pickup at Edinburgh, Glasgow, or Inverness airport.
Roundabout-heavy tourist corridors along Paphos, Limassol, and Larnaca, the metric speed surprise for American drivers, the summer heat tax, and a calmer first hour after pickup at LCA or PFO.
The time tax NZTA flags directly, one-lane bridge rules, the Crown Range and Haast Pass realities, gravel-road rental restrictions, and the fatigue problem after a transpacific flight.
Left-side rules, narrow rural roads, rental-car choices, insurance, and a calmer first pickup. For travelers nervous about the first drive after landing in Dublin, Cork, or Shannon.
What actually changes for a US driver in the UK - left-side traffic, roundabouts, narrower roads than home, and how to design a calmer first day.
Which international driving permit Japan accepts, what to confirm at the rental counter, and how to plan a first drive that leaves room for the switch to keeping left.
A practical, country-neutral checklist for the trip itself: rental car setup, the first 10 minutes in the car, roundabouts, the moments where old habits return, and how to rehearse before you travel.
Why licensed drivers drift to the right after a turn - and what motor-learning research says about rebuilding the instinct. For anyone nervous about driving on the left for the first time.
The geometry of clockwise circulation, the physics of crossing oncoming traffic on a right turn, and the discipline of keeping left after a turn instead of drifting back to old patterns.
LeftLane is a free browser simulator that puts you in the moments these guides describe - the right turn, the clockwise roundabout, the post-turn drift. New to it? See how a simulator helps you prepare.
