The particle を marks the direct object of the verb.
Here, the verb is 避けて from 避ける, meaning to avoid.
So:
The roads are what is being avoided, so they take を.
The て-form connects actions.
Here, 避けて帰ります means something like:
So 避けて links to 帰ります.
This does not necessarily mean two completely separate actions in strict order. It often shows that the first action is connected to the second, or describes the way the second action is done.
Usually it is understood more naturally as go home while avoiding dangerous roads.
The て-form can show sequence, but in this kind of sentence it often expresses the manner or condition of the main action.
So the nuance is closer to:
rather than two sharply separated actions.
帰ります comes from 帰る, which means to return or to go home.
In everyday Japanese, 帰る is very commonly used for going back to one’s home or usual place.
So:
It sounds natural here because the sentence is about the route someone takes when heading home.
The subject is omitted, which is very common in Japanese.
From context, it could mean:
In many textbook-style sentences, English learners often understand the hidden subject as I unless context suggests otherwise.
Because 雨の日 is being presented as the topic, not just as a time setting with で.
Japanese often marks time expressions directly without a particle, or uses は when the speaker wants to make that time expression the topic.
So:
Using で here would sound unnatural, because で usually marks a place of action, means, cause in some cases, and other functions—but not this kind of simple time-topic expression.
The comma is mainly for readability.
In 雨の日は、危ない道を避けて帰ります。, the comma creates a small pause after the topic:
It helps separate the topic from the rest of the sentence, but it is not mandatory. The sentence could also be written without the comma:
Both are fine.
Yes. Because 帰ります is in the non-past polite form, it can describe:
In this sentence, with 雨の日は, it most naturally sounds like a habit or usual behavior:
So it is not just about one specific rainy day unless context makes it specific.
