Road trips & drivingRenting a car or campervan is the undisputed best way to explore New Zealand's South Island, but American travelers often feel a spike of anxiety at the thought of driving on the left side of the road. With clear mental models, the transition takes less than an hour of driving, but New Zealand's specific road quirks — single-lane wooden bridges, winding mountain passes, and unpaved gravel pullouts — require focused attention.

The golden rule for keeping your bearings is simple: keep the driver in the middle of the road. Since New Zealand vehicles place the steering wheel on the right, positioning yourself near the road's center line ensures your car stays properly centered in the left lane.
Turning right requires crossing oncoming traffic and is where tired drivers risk reverting to muscle memory. Pause and double-check before executing right turns. Note that windshield wiper and turn signal stalks are flipped in Japanese-manufactured rental cars — expect to turn on your wipers instead of your blinker on day one.
New Zealand highways feature hundreds of one-lane timber and concrete bridges, especially across the South Island. Road signs before each bridge dictate right-of-way with red and black arrows.
A circular sign with a red border and a prominent red arrow pointing forward means you must yield and give way to oncoming vehicles already on or approaching the bridge. A blue rectangular sign with a heavy white arrow pointing forward gives you right-of-way, though defensive drivers should always verify oncoming cars are stopping.

Open highways carry a maximum speed limit of 100 km/h (roughly 62 mph), strictly enforced by hidden speed cameras and police radar with minimal tolerance for speeding. In towns and rural school zones, limits drop to 50 km/h and 30 km/h.
If you are operating a heavy campervan on winding roads, use the paved slow-vehicle turnout bays (passing bays) whenever two or more vehicles queue behind you.

Yes, US citizens can legally drive in New Zealand for up to 12 months using their valid state driver's license, as long as it is in English.
If the red arrow points in your direction of travel, you must give way to oncoming cars. If the large white arrow points in your direction, you have right-of-way.
State highways are fully paved and well maintained, but they are frequently narrow, winding two-lane roads with few multi-lane expressways outside Auckland.
