The move stems from a Cabinet resolution on December 20, asking government agencies to offer so-called “New Year gifts” to the tax-paying public.
High Department director-general Sarawut Songsivilai said on Monday that M-Flow registrations were still rising after the new payment system was introduced at the start of last year.
He added that the system was convenient to use and also helped reduce congestion at toll booths.
To register for the discount, visit www.mflowthai.com, the MFlowThai smartphone app or @mflowthai Line official account, or contact the department's call centre at 1586 ext 1.
