Dear Rabbi,

Can one place branches over the open sunroof of one's car in order to create a valid succah?

Dear Name@Withheld,

The mishna says "One who makes a succah on a wagon, or on a ship, it is a valid succah."

However, a succah has certain minimum dimensions of height and area. The sunroof must be at least 7 x 7 halachic handbreadths (approximately 70 X 70 cm) and the walls must be at least 10 halachic handbreadths high (approximately 100 cm). Ideally, the branches which cover the sunroof should not sit directly on the metal of the car; but rather, they should rest on top of other wood or branches.
