Final answer:
Upon encountering a truck crash not involving hazardous materials, stop and do not interfere with emergency response teams. For a meteorite crash at home, contact local authorities, then check with your insurance for coverage, and handle the meteorite cautiously, seeking professional advice.
Step-by-step explanation:
If you come upon a crash with a truck and determine it is not hazardous material, the first step you should take is to stop and not interfere with emergency services. You should not run toward the ambulance nor should you run alongside it, as this could interfere with the responders and potentially put yourself in danger. It's also important to assess your safety and the safety of your passengers before you consider helping others.
In a situation where a small meteorite has crashed in or near your home, the suggested protocol could be to call local authorities first to report the incident and for guidance. Next, contacting your insurance company to inquire about coverage for any damages would be prudent. Handling the meteorite should be done with care, following advice from authorities, and you may want to seek a professional appraisal or advice from a scientist.
