At what speed must heavy vehicles travel on freeways?

Heavy vehicles are required to travel at a speed limit of 80 km/h on freeways. This regulation is in place to ensure both safety and the efficient flow of traffic. Heavy vehicles, which may include trucks and buses, have different handling characteristics compared to lighter vehicles, and their larger mass means they require more time to stop. Therefore, a speed limit of 80 km/h helps accommodate these factors, reducing the potential for accidents and ensuring that heavy vehicles can safely navigate alongside lighter traffic.

Higher speeds could pose risks not only for the drivers of these vehicles but also for other road users. By adhering to the 80 km/h limit, heavy vehicles can better manage their braking distances and maintain control, enhancing overall road safety.
