Which of the following statements about forklift operations is incorrect?

Friction plays a critical role in forklift operations, and the dynamics of how it changes in different weather conditions are essential for safe forklift handling. The statement that friction increases in rainy weather is incorrect because, in fact, rain typically creates a slicker surface due to the presence of water, which can reduce the friction between the tires of the forklift and the surface. This can lead to increased stopping distances and a higher risk of losing traction.

In contrast, the other statements provided are accurate and essential practices for safe forklift operation. Operating with caution is vital to ensure the safety of the operator, materials being handled, and personnel nearby. Adhering to maximum load capacities is crucial to prevent accidents and maintain stability. Additionally, while forklifts can be designed for various conditions, they generally perform less effectively and with more risk on wet surfaces compared to dry surfaces, highlighting the importance of understanding environmental factors in forklift operations.
