There is one "motorway", from Bandar Seri Begawan (the capital) along the coast. It devolves into dual and then single carriageway but is suitable for all vehicles, right through to Kuala Belait and the toll bridge to Malaysia/Sarawak in the west)
There is also a side road off this, which runs into the jungle towards the settlement of Labi and beyond. Excellent scenery, and a 4-wheel drive may be useful, but the road is now sealed up to the longhouses some distance beyond Labi. Stock up on water at the convenient shop at the junction.

By taxi
There are only ± 40 taxis in whole Brunei (2009), because the car ownership and usage are high. Since there are around 10 waiting at the airport and 8 in the Belait District there is a little chance of finding a free taxi along the road, especially during morning and afternoon peak hours when they are hired by business men. Needing a taxi might require a phone call. The main taxi stand is direct north of the bus station in the capital with only a few taxis waiting.
None of the taxis has a taxi meter since there is no taxi company nor regulation requiring to have one. Drivers have fixed prices for most trips, although the tariffs may vary between different drivers, or they will give a price for an irregular trip.

By tour vans
Another alternative is hiring a tour van to drive you around Brunei, for example, for a whole day, or several hours. Try asking them from the ferry counters in Muara. Discuss the price first before agreeing to board the van.

Waterways

By bus
Around the capital, Bandar Seri Begawan, there is a good-sized network of purple minibuses. Brunei's high rate of private car ownership means very few Bruneians take these buses, which largely cater to foreign workers. The speed of the buses are limited to 50km/h but are actually quite efficient and reliable.
In general, the bus system around the capital radiates from the bus terminal in the central district. There are designated bus stops along each route but passengers are picked up or let off at unofficial locations at the discretion of the driver. The unofficial mode of operation makes easy travel and entice patronage. Unfortunately, it is difficult to obtain some form of details on bus routes and timetables. Recent experience in mid 2011 prompted a small contribution in the form of pictures of the known bus routes at the time.(The pictures of the bus routes will be posted at a later date). There are 13 routes and the fare is flat B$1.00 which is collected by a conductor. The passenger can advise the driver the location to disembark. Sometimes, the conductor asks the passengers their respective locations to disembark and skips part of the route, to the dismay of passenger who wish to catch the bus. This also implies that there is no strict scheduled time. It is quite normal to wait 30 to 45 minutes for a bus.
There is also an infrequent long-distance bus which runs between BSB and Seria through Tutong.
