Okay, so I recently ordered something from Amazon, and they're shipping through UPS. The delivery estimate is 4-5 business days. I understand that trailer drivers don't make progress on weekends, or do they?.. The order is from California and I am in Maryland, do the trailer drivers make progress on weekends? And if they don't, when do they start delivering on the week days again? For example, Saturday and Sunday, no delivery, do they start making progress again at 1AM the following Monday.
