When the name is Janice "Lokelani" Keihanaikukauakahihuliheekahaunaele, the answer is a LOT of letters.
Like 36 in the last name alone.
And now the Hawaiian woman is able to have each and every letter of that freight-train of a name on her driver's license and state ID card.
The state Department of Transportation had a policy that left room for names up to 35 characters.
But her name has 35 letters, plus an okina - a mark used in the Hawaiian alphabet.
Keihanaikukauakahihuliheekahaunaele fought to change the rule - and now state policy allows 40 characters for last names, 40 for first names and 35 for middle names.
