Final answer:
When taking a trip during the winter, it is important to keep the fuel tank more than half full to prevent condensation in the tank and ensure preparedness.
Step-by-step explanation:
When taking a trip during the winter, one thing you should do is keep the fuel tank more than half full. This is because colder temperatures can cause condensation in the fuel tank, leading to water accumulation. By keeping the fuel tank more than half full, you can minimize the space for condensation to occur. Additionally, having a sufficient amount of fuel can help in case of unexpected delays or emergency situations.
