RHD

Right-hand drive (RHD) means the steering wheel, pedals, and gear shift are positioned on the right side of the vehicle cabin, making the driver sit on the right. This is the mirror image of left-hand drive (LHD) layout, where controls are on the left. The choice depends on which side of the road a country drives on: RHD vehicles are standard in the UK, Japan, India, Thailand, Australia, and several other nations that drive on the left.

The practical consequence is that the driver sits closer to oncoming traffic and has a better view of the near side of the road. Conversely, the passenger is positioned toward the kerb or shoulder. This affects visibility for reversing, parking perception, and toll booth interaction. When RHD vehicles are exported to LHD markets, or vice versa, they command lower resale prices because buyers must adapt to the unfamiliar layout.

Manufacturing and cost

Manufacturers producing for both RHD and LHD markets typically design platforms that can be mirrored. Major components like the dashboard, wiring harness, brake and fuel line routings, and door hinges must be reversed. Some models use a single global platform with swappable left and right assemblies; others maintain separate production lines. Japanese and British manufacturers have extensive RHD expertise because their home markets demand it. Conversely, American and German makers often treat RHD as a lower-volume variant, which increases unit cost.

Trade in used RHD vehicles is strongest within regions that use them. A five-year-old Japanese RHD sedan sells readily in Japan, Southeast Asia, and the Pacific; the same car in the US has limited buyers and typically sells at a steep discount. This creates arbitrage opportunities but also inventory challenges for dealers and rental companies operating across markets with different steering conventions.

Terminology can blur: the term 'right-hand drive' refers strictly to the steering position, not to which side of the road you drive on. A vehicle is RHD or LHD by design; a country is left-driving or right-driving by law. Japan is a left-driving country that uses RHD vehicles; the UK is also left-driving and RHD. The US is a right-driving country that uses LHD vehicles. Confusion between these terms has caused costly procurement errors in fleet and export operations.
