Samoan drivers drive on the left side of the road. Samoa began driving on the left side of the road in 2009. Since then, there has been a flood of inexpensive, refurbished vehicles from Japan, and hitherto unseen traffic bottlenecks have been frequent in Apia, the capital. Even on routes outside of the city, traffic moves slowly owing to cautious and inexperienced drivers, as well as many speed bumps.
In general, this is your best bet. They are inexpensive and abundant. The Samoa Tourism Authority has a pricing list for Apia, which may be located in front of the Government office complex on Beach Road, Apia. Agree on a fee ahead of time; if they believe you are wealthy, they may attempt to overcharge you. For roughly the same amount as a rental vehicle, you may hire one for the whole day.
Because foreign driving permits are not recognized, you must acquire a temporary local license. These are easily obtained at the Apia police station or from a variety of vehicle rental companies. Details about vehicle rental companies may be found on the sites for Upolu and Savaii.
Buses are inexpensive, and taking one will be an unforgettable experience. Buses on Upolu depart from two Apia locations: near the main market and behind the flea market. All paths on Savaii begin near the ferry port at Salelologa.
Although possible and pleasant, ‘Upolu has a few pretty steep and mountainous parts, and the cross-island routes are approximately 7km hard upward to their crests. Savai’i only has two or three short steep parts (around the western end).
