The full form of LHT is Left-hand traffic.
LHT refers to the system where vehicles drive on the left side of the road. This is in contrast to right-hand traffic (RHT) systems, where vehicles drive on the right side of the road. Here's a breakdown of what that means:
Understanding Left-Hand Traffic (LHT)
Key Characteristics of LHT
- Driving Position: In LHT systems, the driver's seat is typically on the right side of the vehicle.
- Lane Usage: Vehicles travel on the left side of the road.
- Passing: Passing or overtaking other vehicles usually happens on the right side.
- Roundabouts/Traffic Circles: Vehicles typically travel clockwise around roundabouts.
LHT vs RHT: A Comparison
Here's a table summarizing the main differences:
| Feature | Left-Hand Traffic (LHT) | Right-Hand Traffic (RHT) |
|---|---|---|
| Driving Side | Left | Right |
| Driver's Seat | Right | Left |
| Passing Side | Right | Left |
| Roundabout Flow | Clockwise | Counter-Clockwise |
Examples of Countries Using LHT
Many countries around the world use LHT. Some notable examples include:
- United Kingdom
- Japan
- India
- Australia
- South Africa
- Ireland
Practical Implications of LHT
- Driving on the "wrong" side: For people used to RHT, driving in a LHT country can be challenging initially and requires extra attention to road positioning and other vehicles.
- Car Design: Vehicle designs are adapted for LHT countries. Vehicles produced for LHT driving have their driver's seat on the right and the controls designed accordingly.
- Road Markings and Signs: Road signs and markings are also made according to LHT conventions, which can be very different to those used in RHT countries.
Conclusion
LHT is a fundamental aspect of road traffic management, impacting vehicle design, road infrastructure, and driver behavior. Understanding the specific driving rules within LHT systems is essential for anyone navigating a country that employs this standard. The term refers explicitly to a road system in which all traffic travels on the left.
