The car being transported is green.

Dear to whom may it concern,
[color=green]The car being transported is green. ‘To be ‘was omitted for shorting the sentence, is it a kind of gerund sentence? And also Can I write [color=green]the car is being transported is green?

Your question is unclear to me, but referring to the photo:

The car being transported is green. – The writer considers that the car is now in process of transportation.
The car to be transported is green. – The writer considers that the car is not yet in the process of transportation; it is merely being readied for transport.

Both interpretations are valid.

If you were to write the full sentence, you would need to say “The car that is being transported is green”. It is often shorted because “to be” is already used once.

Dear teachers,
Thank you very much indeed.
