Typical minor road rage (7)

I believe the answer is:

average

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

'typical' is the definition.
(I've seen this before)

'minor road rage' is the wordplay.
'minor road' becomes 'ave' (abbreviation for avenue. I am not sure about the 'minor' bit.).
'ave'+'rage'='AVERAGE'

Can you help me to learn more?

(Other definitions for average that I've seen before include "Mean - ordinary" , "Run of the mill" , "mean maybe" , "Arithmetical mean" , "Arithmetic mean" .)

I've seen this clue in The Telegraph.
