Right-Hand Drive (RHD) refers to vehicles designed with the steering wheel on the right side, allowing the driver to sit on the right. This configuration is common in countries where vehicles drive on the left side of the road, such as United Kingdom, Australia, and Japan. In RHD vehicles, the placement of controls and mirrors is adjusted for optimal visibility and safety. This design contrasts with Left-Hand Drive (LHD) vehicles, where the steering wheel is on the left side, typical in countries like United States and Canada. Understanding RHD is essential for safe driving in regions that follow this system.
