It is necessary to have an extra space of cushion around your vehicle when driving near construction workers for safety reasons.
Step-by-step explanation:
When driving near construction workers, it is necessary to have an extra space or cushion around your vehicle for safety reasons. This is because construction workers often work in close proximity to moving vehicles, and having a buffer zone allows for any potential accidents or mistakes to be mitigated. It provides a safety margin in case a worker or object comes into the path of your vehicle, allowing for more time to react and avoid a collision.
