In which conditions can the legal maximum weight pose a risk?

The legal maximum weight can pose a risk in bad weather and on mountains because these conditions significantly impact vehicle stability and handling. When a vehicle is loaded to the maximum legal weight limit, its ability to maneuver and respond to road conditions can be compromised, particularly on steep inclines or declines often found in mountainous terrain.

In bad weather, such as rain, snow, or ice, the stopping distance increases, and traction decreases, making it harder to control a heavily loaded vehicle. This can lead to a greater likelihood of accidents or rollovers, especially when navigating sharp turns or slopes. Therefore, operating at maximum weight in such conditions demands heightened caution and skill from the driver to maintain control and ensure safety.

Other conditions like straight flat roads or traveling at lower speeds generally provide safer driving parameters, as the impacts of weight become less pronounced in terms of stability and stopping distance. Additionally, driving at night doesn't innately increase the risks posed by vehicle weight but rather affects visibility.
