Unless otherwise posted, what is the standard speed limit on highways and roads in Korea?

Answer: B — 100 KPH

The standard speed limit on highways and roads in South Korea is 100 kilometers per hour (KPH). This limit is established to provide a balance between safety and efficiency for vehicles traveling on major thoroughfares. Areas with less traffic congestion and higher road quality support this speed, allowing drivers to cover distances more quickly while maintaining a level of safety. In addition, speed limits can be subject to change based on road conditions, weather, and specific local regulations, but the baseline speed for highways, unless stated otherwise, remains set at 100 KPH. This helps promote uniformity and predictability for drivers throughout the country, enhancing overall road safety and traffic flow.
