What is indicated by sign J8?

Sign J8 is specifically used to indicate the maximum speed allowed at night. This is crucial for drivers as nighttime conditions can significantly differ from daytime, often resulting in reduced visibility. The sign helps to ensure that drivers adjust their speed to maintain safety. It emphasizes the importance of driving at a safe speed at night, which is generally lower than during the day. By adhering to this speed limit, drivers can respond more effectively to unseen obstacles, pedestrians, or any other potential hazards that may arise when visibility is compromised.
