If I'm in a bus or a train and I'm on the phone, would it be correct to say my interlocutor that "I'm in transports" with the meaning that "I'm in a public transport".
In French, saying "Je suis dans les transports" (direct translation of I'm in transports) would be understood as "in public transports" by everyone, but I'm really unsure it's the same in English.
Google didn't help much on that, results for "I'm in transports" are not convincing.
And if it's not correct, how could I say that the proper way ?
