A
single-decker bus or
single-decker is a
bus that has a single deck for
passengers. Normally the use of the term
single-decker refers to a standard two-
axled rigid bus, in direct contrast to the use of the term
double-decker bus, which is essentially a bus with two passengers decks and a staircase. These types of single-deckers may feature one or more doors, and varying
internal combustion engine positions.
