RHD, or right-hand drive, refers to a type of vehicle configuration where the steering wheel is located on the right side of the car, as opposed to the more common left-hand drive configuration. This type of setup is typically found in countries where traffic flows on the left side of the road, such as the United Kingdom, Japan, and Australia. RHD vehicles are designed to provide better visibility and control for drivers in these countries, and are often imported to other countries as well. While it may take some getting used to for those accustomed to left-hand drive, RHD vehicles offer a unique driving experience and are a common sight on roads around the world.
