What should be done to ensure safety on slippery surfaces?

Answer: C — Reduce speed and avoid sudden moves

To ensure safety on slippery surfaces, reducing speed and avoiding sudden moves is key. Slippery surfaces, such as those caused by rain, ice, or gravel, can significantly decrease traction and control over the motorcycle. When speed is reduced, the rider has more time to react to potential hazards and can maintain better control of the vehicle. Making sudden turns or rapid maneuvers can lead to loss of balance or skidding, increasing the likelihood of an accident. Using only the front brake can also cause the motorcycle to tip over or lose traction since it places excessive weight on the front tire, making it more prone to slipping. Therefore, reducing speed while remaining smooth and deliberate in steering and braking is the safest approach when navigating slippery conditions.
