The serving girl spread warning that vehicle is rolling back (9,5)
I believe the answer is:
reversing light
'warning that vehicle is rolling back' is the definition.
The definition suggests a singular noun which matches the answer.
'the serving girl spread' is the wordplay.
'spread' is an anagram indicator.
'the'+'serving'+'girl'='theservinggirl'
'theservinggirl' anagrammed gives 'REVERSING LIGHT'.
