What should you do first if your vehicle's gas light comes on?

Answer: B — Find the nearest gas station and refuel

When your vehicle's gas light comes on, it is essential to prioritize finding the nearest gas station and refueling. The gas light serves as an indicator that your fuel level is critically low, and continuing to drive on empty can lead to several issues, including getting stranded on the road or damaging the fuel system. Refueling promptly helps ensure that you maintain adequate fuel for the car to operate efficiently. Ignoring the gas light or waiting until it blinks to take action can lead to running out of fuel completely, which can be inconvenient and unsafe. Prioritizing a quick stop at the nearest gas station makes this situation manageable and keeps your vehicle in proper working order, reducing the risk of engine damage that can occur from running on an extremely low fuel level.
