**Novice drivers** can travel at a **maximum speed of 120 km per hour** on highways and expressways. This is because, on these roads, it is considered safe to drive at this maximum speed, as they are designed to support faster and smoother traffic. Additionally, highways and expressways have features that allow for safer driving at higher speeds, such as wide lanes and fewer intersections.


In contrast, on roads that are neither highways nor expressways, the maximum permitted speed is 90 km per hour to reduce the severity of accidents. Therefore, the speed of 120 km per hour is specific to highways and expressways, and it is the maximum speed allowed for novice drivers on these roads.
