Park in lane illegally after a hundred and ten crashed (10)

Ross

I believe the answer is:

centennial

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

'park in lane illegally after a hundred' is the definition.
I can't judge whether this definition defines the answer.

'ten crashed' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'ten' is 'ent' which is located in the answer.
This explanation may well be incorrect...

'and' is the link.

Can you help me to learn more?
