5 to a motorcycle

Our school's "ambulance" is a motorbike. Right now, during "malaria season", our 260 school students are getting sick at an alarming rate. There's often a line of children waiting to be taken to the medical clinic, 1 kilometer from the school. Yesterday, I saw the ambulance leave the school...the driver and 4 children: back-to-back-to-back-to-back-to-back! What ambulance would we use if they had an accident?!
