Distracted driving actually plays a large role in the cause of these accidents. While the goal of the USPS is always to maintain or improve safety, accidents are not always preventable. With the recent increase of on-demand content, cell phone technology, and distracting screens, there is no perfect answer to this problem. Countless apps, sounds, and calls make it difficult to completely ignore our devices. Other causes of post office vehicles accidents include driving in poor weather conditions and insufficient training.
