Left- and right-hand traffic
Left-hand traffic (LHT) and right-hand traffic (RHT) are the practices, in bidirectional traffic, of keeping to the left side or to the right side of the road, respectively. They are fundamental to traffic flow, and are sometimes referred to as the rule of the road. The terms right- and left-hand drive refer to the position of the driver and the steering wheel in the vehicle and are the reverse of the terms right- and left-hand traffic.
In LHT traffic keeps left, and cars usually have the steering wheel on the right (RHD – right hand drive). Roundabouts circulate clockwise. RHT is the opposite of this: traffic keeps right, the driver usually sits on the left side of the car (LHD – left hand drive), and roundabouts circulate anti-clockwise.
Note that the VLAND headlights will use LHD and RHD to distinguish between different versions to adapt to local road traffic rules. We will send the correct version based on the road traffic rules of your shipping address.
