Run on Or Not - Example from Manhattan

The following example is from the same source -

"The players' helmets need to be repainted before they are used in Sunday's game."

I read on the internet that "when you attach a subordinate clause at the end of a main clause, you will generally use no punctuation". Is the reasoning correct?

Is the above sentence a run-on?

I think the sentence is correct because those are dependent. Sentence starts with 'when' stating that there is an action after that,so I feel it is not run-on. ( I am also beginner in GMAT so please dont mind If I am wrong and also please feel free to correct my comment)

Hi,

Did you find any example which has this particular structure?

i don't want to rely much on intuition in SC..

Infact I haven't found any example but as per I studied from few sources, if there are independent and dependent clauses in a sentence then we need to use comma after the independent clause and after that dependent clause comes, I think if we see your actual sentence ( that starts with when) try to look in this way, if we keep comma after the when clause, will it make any meaning. If it makes a meaning then we can use comma otherwise we cannot use. I am trying to find more accurate information on this for you, if I find any other information I will post it here.

I think there is a run-on error.
The correct sentence should be:

"When the guests finished their soup, they were brought plates of salad."

Comments please...

My bad..

This sentence is not a run-on, but as per the rule posted in the other sentence in the forum, the subordinate clause should follow the main clause.

I still don't have clarity .. Anyways will update, once i get additional info.

I agree with you, the way I understood is, if there is no When in the beginning of the sentence then you can keep comma after the independent clause and can continue dependent clause after comma, anyway you got a solution. good to hear
