What is the maximum speed limit for large passenger vehicles on national expressways?

The maximum speed limit for large passenger vehicles on national expressways in Japan is set at 100 km/h. This limit is established to ensure the safety of all road users while allowing for efficient travel on highways designed for higher speeds. Large passenger vehicles, which include buses and other big vehicles, are subject to a slightly different regulation than smaller vehicles. The regulation aims to balance speed with safety, considering the size and handling characteristics of larger vehicles.

Choosing a speed limit of 100 km/h allows for a safe operating environment while also promoting smoother traffic flow on expressways, which are intended for faster travel as compared to local roads. This ensures that larger vehicles can maintain adequate control and response times on such high-speed roadways. Additionally, it's important to remember that speed limits may vary on different types of roads and various vehicle classifications, which is why knowing the specific limits is crucial for drivers.
