They may also help with navigating routes, handling customer interactions, and managing paperwork or electronic documentation. The driver helper's responsibilities are essential in reducing the workload of the driver, especially during busy periods or when handling large or heavy items, ultimately contributing to a smooth and successful delivery process. Their assistance helps improve overall service quality and customer satisfaction.
