Could you explain to me which of the sentences below is correct and why?
You should ban cars from city centers.
You should ban cars in city centers.
I suppose that the first sentence is a proper one, but I can’t understand why there is a preposition from.
This is an example from an online dictionary freesearch.co.uk, take a look at this:
She was banned from driving for two years.
This case is a coherent one for me.
Maybe there are other similar examples like this above, you mean, a verb + from if you want to express prohibition.
