But maybe a rutted gravel road and perhaps too much speed and it may bring things to a halt.
The USPS prides itself on making deliveries no matter what, but this was not what they had in mind, a mail truck turned upside down on Cloud Road in a county island in Chandler near Riggs and Cooper.
"Physically what happened I don't know, how he ended up in that position you can see. All's well that ends well, he didn't get hurt from what I know," said Glade Swenson, who lives nearby.
There are some ruts in the road where the accident happened. FOX 10 drove down Cloud Road to take a look for ourselves. Here and there it can be a rough ride.
So what caused the accident? Authorities say it is still under investigation, but if you're going too fast and you hit a rut you could have a problem.
"This is not the first-time somebody's flipped... a couple of years ago there were some kids driving too fast, and they wound up in somebody's front yard also," said Kierstin Hossele.
The Postal Service says it is investigating the accident; meanwhile neighbors have some advice.
"Slow down, we are a residential neighborhood like all others, we just happen to have dirt roads and they seem to think it is a racetrack," she said.
