The District of Columbia and New York State are both members of the Drivers License Compact so New York courts will inform the DC Department of Motor Vehicles.

According to the District of Columbia DMV, drivers receive points for certain moving traffic violations, whether the violations occur in the District of Columbia or in other states. The DC DMV will assess points if you are found liable at a hearing, fail to pay a ticket within the time required, are convicted in court of a traffic violation, or you pay the ticket (thus admission of liability). The number of points you will receive depends on the type of violation.

Failure to yield on a left turn is not listed on the DMV points list specifically so likely falls under the offense of "commit any moving violation that does not contribute to an accident and is not listed" which means it would be assigned 2 or 3 points.

Since the NYC moving violation will be placed on your DC driver's license your insurance will see it the next time they pull your motor vehicle record (MVR) and thus it could affect your auto insurance rates. If the traffic ticket will affect your rates will depend upon your insurance carrier’s rating system. To find out about your provider’s rating system check with your insurance agent.
