Class 3 typically refers to a category of vehicles that are designed for specific uses, often including larger trucks and buses. These vehicles usually have a gross vehicle weight rating (GVWR) between 10,001 and 14,000 pounds. They are commonly used for commercial purposes, such as transporting goods or passengers. In the context of education, Class 3 can also refer to a grade level in primary schools, where students are usually around 8 to 9 years old. At this stage, children often learn foundational subjects like math, science, and language arts, helping to build essential skills for their future education.
