Random parking in ditch first and road after - this vehicle is South African (9)
I believe the answer is:
haphazard
'random' is the definition.
(similar in meaning)
'parking in ditch first and road after this vehicle is south african' is the wordplay.
I cannot quite understand how this works, but
'parking' could be 'p' (abbreviation on road signs) and 'p' is present in the answer.
'ditch' could be 'haha' (type of ditch) and 'haha' is present in the remaining letters.
'first' could be 'a' and 'a' is present in the answer.
'road' could be 'rd' (abbreviation) and 'rd' is present in the answer.
A single letter 'z' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for haphazard that I've seen before include "Erratic" , "Careless or random" , "Disorganised, random" , "Lacking any obvious organisation" , "Slapdash, slipshod" .)
