Automotive test (3)

I believe the answer is:

mot

I'm a little stuck... Click here to teach me more about this clue!

'test' is the definition.
(MOT test)

'automotive' is the wordplay.
'MOT' is hidden in amongst the letters.
But, I'm unsure how this is indicated.

Can you help me to learn more?

(Other definitions for mot that I've seen before include "Wisecrack (for older cars!)" , "A French word, may be bon" , "French word for Tom" , "type of test" , "Witty saying" .)

I've seen this clue in the Evening Standard.
