Open transport
Open transport moves a car on a shared trailer with no roof or walls. It is the usual way a daily driver ships. Rain, dust, and road debris can reach the car. It is not enclosed transport.
Open transport uses an open trailer, the kind you see on the highway with cars stacked on two decks. Your car shares the trailer with other vehicles. The top spot is more exposed to sun and to whatever the road throws up. The lower spots sit closer to the wheels of the truck.
What the weather can do
There is no roof. The car gets wet. It can collect dust, bugs, and small chips from gravel. Carriers treat that as normal for open service. A new dent is a different event, and it belongs on the delivery condition report. Wash the car only after you have photos. Dirt can hide a mark, and it can also be the only reason a panel looks dull.
How it differs from enclosed transport
Enclosed transport uses a hard-sided trailer and a different rate. Open is not enclosed with a discount stuck on it. If the car is a daily driver you already park outside, open is the ordinary choice. If you cannot accept stone chips, ask for an enclosed quote on the same lane and read both. RideShipper does not operate trailers. The open versus enclosed comparison is the longer version of this choice.
