At entry, to driver

This practice, when the front passenger door is used for entry to the vehicle, enables the driver to monitor the flow of passengers and check for travel payment. Where the driver collects fares from passengers on entry and issues tickets, then the facilities to install the ticket issuing machine and the secure holding and issuing of small change must be designed into the cab area. Sometimes in the cab area, protective screens are provided to deter theft from the driver or robbery.

However, where the vehicle only has one door, the stop dwell time is increased because the alighting passengers need to leave the vehicle before entering passengers can board. Examples exist of extra wide doors that enable the segregation of alighting and entering passengers. Sometimes a second or more doors on the vehicle are available to alighting passengers, but the risk exists that some passengers may use those doors to enter without passing the driver.

Where the majority of passengers possess pre-paid travel documents that do not require on-board cash transactions, then the speed of the flow of passengers passing the driver is quicker. Unless the driver checks tickets on exit as well as on entry [which further increases the stop dwell time], with this practice they cannot easily identify those passengers that are travelling beyond the distance that their ticket entitles them to.
