Native American in hired vehicle touring Rhode Island (5)
I believe the answer is:
carib
'native american' is the definition.
(member of a native people of South America)
'hired vehicle touring rhode island' is the wordplay.
'hired vehicle' becomes 'cab'.
'touring' means one lot of letters goes inside another (touring can mean going round).
'rhode island' becomes 'ri' (US postal abbreviation).
'cab' enclosing 'ri' is 'CARIB'.
'in' acts as a link.
(Other definitions for carib that I've seen before include "Indian" , "S. American language" , "Native and language giving name to a sea" , "Native of West Indies and northern South America" .)
