Its speed is changed to prevent head-on collision (8)

I believe the answer is:

sidestep

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

'prevent head-on collision' is the definition.
I can't judge whether this definition defines the answer.

'its speed is changed' is the wordplay.
'is changed' indicates an anagram.
'its'+'speed'='itsspeed'
'itsspeed' with letters rearranged gives 'SIDESTEP'.

'to' acts as a link.

Can you help me to learn more?

(Other definitions for sidestep that I've seen before include "Find a way round" , "Dodge - circumvent" , "To avoid" , "Shift to right or left" , "Dodge (an issue?)" .)

I've seen this clue in The Globe and Mail.
