Left-hand traffic (LHT) is a system where vehicles drive on the left side of the road. This means that the driver's seat is typically on the right side of the vehicle. Countries like United Kingdom, Australia, and Japan follow this traffic rule. LHT is designed to enhance safety and improve the flow of traffic, especially in areas where road designs are influenced by historical factors. In LHT countries, roundabouts and intersections are organized to accommodate left-side driving. For example, when making a right turn, drivers must cross oncoming traffic, which can be challenging for those unfamiliar with the system. Understanding LHT is essential for safe navigation in these regions.
