As I suspected from the NJ plumbing code of 2021…
One trap for a multi compartment sink is allowed… (exception 3) but it is a ‘May’ not a ‘shall’. This means you can do one trap per sink compartment or one trap for both.
What is NOT allowed is putting 2 traps in series (one after another) without a vent between them (5.1c).
Read the code in your jurisdiction, be mindful of the ‘shalls’, ‘Mays’, and ‘musts’…
