If you are involved in a traffic stop as a passenger, you may leave if you are not detained.

True

True.
If you are a passenger in a vehicle that has been stopped by law enforcement and you have not been individually suspected of any wrongdoing or detained, you are generally free to leave the scene. However, it is crucial to keep in mind:

1. You should ask the officer for permission to leave to ensure that you are not being detained or are not needed for questioning.
2. If the officer requests that you stay, it is advisable to comply with their instructions to avoid escalating the situation or facing potential charges for obstruction.
3. If you choose to leave, do so calmly and do not interfere with the ongoing traffic stop.

Remember that laws may vary by jurisdiction, so it is always best to cooperate with law enforcement and seek legal counsel if you have concerns about your rights during a traffic stop.
