The bus driver who, only works weekdays, always waits for me when i'm running latecorrect the comma sandwich

The bus driver, who only works weekdays, always waits for me when I'm running late

Explanation:

Hi, to answer this question we have to know what a nonrestrictive clause is, and how we use commas in these cases.

A nonrestrictive clause adds extra information that isn’t required to understand the main point of the sentence. A nonrestrictive clause should be set off from the main clause with commas.

In this case, the main clause is:

The bus driver always waits for me when I'm running late

And the nonrestrictive clause is:

Who only works weekdays.

So, the correct form is:

The bus driver, who only works weekdays, always waits for me when I'm running late.
