If you are RADAR vectored off the depicted track while executing a SID, what should you do?

When you are RADAR vectored off the depicted track while executing a Standard Instrument Departure (SID), you should consider the SID canceled. This is because a SID is a specific route that pilots are expected to follow after takeoff, and any deviation from this route, especially due to ATC instructions, effectively nullifies the initial clearance to follow that standard path.

When ATC provides a radar vector, they are directing you to follow a specific path that may not align with the SID, indicating that they are providing new navigational instructions. In such cases, you should adhere to the direction provided by ATC rather than attempting to follow the SID, as attempting to comply with both can create navigational conflicts and safety concerns.

While it might seem prudent to continue flying the SID or ask for clarification, those actions could lead to misunderstandings with ATC and potentially unsafe conditions. Acknowledging that the SID is canceled allows you to align your flying with the current air traffic control instructions effectively.
