Which action should you take first if smoke is coming from the engine compartment?

• A. Open the hood
• B. Turn on hazard lights
• C. Turn off ignition
• D. Continue to drive slowly

Answer: (C)

Smoke coming from the engine indicates a potential fire or severe overheating, so the priority is to cut the power to the engine. Turning off the ignition stops the fuel supply and electrical systems, which helps prevent ignition and reduces heat buildup, making it the safest first step. Opening the hood can feed oxygen to a fire or expose you to hot components, so it isn’t the right first move. Turning on hazard lights is helpful for warning others, but it doesn’t address the immediate danger. Continuing to drive keeps the engine running and fuel flowing, which could worsen a fire. Once the engine is off and you’re safely stopped, move away from the vehicle and call for help if needed.
