When you detect smoke coming from your cargo doors, the situation can pose a significant hazard. Opening the doors without taking precautions can lead to an explosion, flare-up, or further spread of fire, especially if flammable materials or hazardous substances are involved.

By waiting until the vehicle is in a safe place and help has arrived, you ensure that the surrounding area is secured and that emergency responders are available to manage the potential dangers. This approach prioritizes safety and helps prevent injuries to yourself and others. It also allows professionals to assess the situation and determine the best course of action before any further steps are taken.

The other options would compromise safety; for example, opening the doors immediately or after turning off the engine could expose you to potentially toxic smoke or flames, while waiting for the smoke to clear might not guarantee that it’s safe to open the doors.
