The correct answer, 'All answers are correct,' is appropriate because in the event of engine failure, multiple actions are required: signaling to move off the road, activating hazard lights, and staying with the car while raising the hood are all part of standard safety procedures. According to BC's driving practices, these actions help ensure the driver’s and others' safety on the road as outlined in the section on Vehicle Breakdown Safety in the ICBC Driver's Guide. It is essential to signal your intention to safely exit the traffic flow, alert other drivers by activating hazard lights, and indicate a breakdown to passersby by raising the car hood, a commonly recognized distress signal.
