It depends on where you live, most suburban and rural areas are designated driver release(leave pkg.) Inner cities, high theft areas, and businesses the driver usually has to get a signature. Unless the shipper requested it, or it's programmed into the barcode, the driver would leave it as long as it is out of sight and out of weather. The last thing I want to do is have to make attempt after attempt. I leave just about everything. I wouldn't sweat it. I've been a driver for 14 yrs. and no telling what I've delivered.
