How should a driver respond to a roadblock?

Answer: B — Follow instructions provided by authorities

When encountering a roadblock, the appropriate response is to follow the instructions provided by authorities. This is crucial for several reasons. Authorities, such as police or road maintenance personnel, are present to manage traffic flow and ensure the safety of all road users. Their signals or instructions may be vital for directing drivers safely around potential hazards, ongoing construction, or emergency situations. By adhering to their guidance, drivers contribute to a safer environment for themselves and others. This ensures that emergency services can operate effectively and that traffic remains organized, minimizing confusion or accidents that could arise from ignoring the roadblock or attempting to navigate it on one's own. Although finding an alternate route can sometimes be necessary, it should be done only if directed or if there is a safe and legal opportunity to do so. Ignoring the roadblock or attempting to speed past it poses risks to the driver and others on the road, undermining the essential purpose of the roadblock itself, which is to manage safety and prevent accidents.
