The 1991 Standards require one van accessible space for every eight accessible spaces. The 2010 Standards require one van accessible space for every six accessible spaces. If you have complied with the 1991 Standards, you are not required to add additional van accessible spaces to meet the 2010 Standards. The 2010 Standards contain new requirements for the input, numeric, and function keys (. “enter,” “clear,” and “correct”) on automatic teller machine (ATM) keypads. If an existing ATM complies with the 1991 Standards, no further modifications are required to the keypad. If a business chooses to.
