What can be the effect of an overload of only 20%?

An overload of just 20% can have several serious effects on a vehicle. First, the brakes may be overstrained because they have to work harder to slow down the heavier load, which increases the risk of brake failure or longer stopping distances. Second, steering can become worse since the extra weight affects how the vehicle responds to steering inputs, making it harder to control. Finally, the additional load puts too much strain on the load-bearing parts, such as the suspension and chassis, which can lead to premature wear, damage, or even structural failure. Understanding these effects helps emphasize why adhering to weight limits is crucial for safety and vehicle performance.
