For a Pakistani woman seeking to travel on a motorcycle, socially sanctioned rules define how she may sit. Although unwritten and unspoken, these are inviolable: First, no girl or woman may drive a motorcycle or clasp the handlebars with both hands. Second, although she can be a passenger behind a male driver, she cannot straddle the pillion seat. Instead, she must perch herself with both legs on the same side and hope she will not fall off. To sit otherwise is considered a violation of female modesty.
