What action should you take when you encounter a pothole?

When encountering a pothole, the recommended action is to stand up slightly on the footpegs to absorb the impact. This method allows the rider to maintain better control over the motorcycle as it traverses the uneven surface. By lifting off the seat slightly, you reduce the shock that travels through the bike, thus preventing potential damage to both the motorcycle and the rider.

Standing up helps the rider to better manage the balance and stability of the bike when hitting a pothole, as the rider's legs can act as shock absorbers. This technique mitigates the risk of losing control, which can happen if too much weight remains in the seat while hitting a pothole.

The other options might lead to unsafe situations. Braking hard before hitting a pothole can unsettle the motorcycle and increase the likelihood of a loss of control. Swerving to avoid it may be dangerous, especially if other vehicles or obstacles are nearby. Accelerating through it can cause significant jarring and can lead to loss of control as well, increasing the risk of an accident. Thus, standing up slightly is the safest and most effective way to handle this obstacle.
