What action should riders take regarding speed when approaching a work zone?

When approaching a work zone, riders should reduce their speed and pay attention to signs. This action is crucial for safety, as work zones can present various hazards such as workers, heavy machinery, and unexpected changes in road conditions. Slowing down allows riders to react more effectively to any sudden changes, such as detours or obstacles, and it also helps ensure the safety of road construction workers who may be present. Additionally, many work zones have posted speed limits that are often lower than normal to account for these increased risks, so being vigilant and adhering to these signs is essential for maintaining both rider safety and the safety of others.
