June 10, 2014 by The Driver 1 Comment. Lyft Minimum Driver Age Now 21 and Commercial Plates. Lyft minimum driver age is now 21. It used to be 23 but with lowering the minimum driver age, this will greatly expand the number of drivers as there are many young people that may be looking to work part time. Lyft has also began to accept commercial and livery plates. Before, Lyft was not allowing any driver to have commercial plates of any kind.
