Why is it advisable to maintain a speed of less than 80 km/h in bad weather?

Maintaining a speed of less than 80 km/h during bad weather is advisable primarily because it allows for better control of the vehicle. Bad weather conditions, such as rain, fog, or snow, can significantly reduce visibility and traction on the road. Driving at a slower speed gives a driver more time to react to unexpected obstacles, road conditions, or the behavior of other drivers.

When the vehicle is moving at a lower speed, the likelihood of skidding or losing control decreases, as the driver has more opportunity to respond to changes in driving conditions. Additionally, it provides a safer distance to stop if necessary, helping to mitigate the risks associated with adverse weather conditions. This practice is crucial for ensuring both personal safety and the safety of others on the road.

The other choices don't directly address the immediate need for driving safely under challenging conditions. Fuel savings, engine performance, and tire wear are important considerations, but they are not the primary focus when it comes to maintaining control during bad weather.
