The New Flyer Industries D40LF was the standard diesel transit bus and first of New Flyer's line of low floor buses. The bus that would become the D40LF was developed by then parent company Den Oudsten Bussen and adapted for the North American market. A revised demonstrator, prototyping the production model, was launched in 1989 as The User Friendly "TUF" Bus. Regular production of the D40LF began in 1991.

After the 2009 model year, New Flyer discontinued the LF series of buses with the traditional style front and rear ends. The D40LF was replaced by the D40LFR. Production for some existing orders of the D40LF continued to the end of 2010.
