Your car dies on a 400-series freeway and you get it onto the shoulder. Should you raise the hood so people can see you need help, and wait outside the car?

Correct answer: C. Neither — leave the hood down, get out through the door away from traffic if you must, and wait inside with the doors locked

Neither. The Driver's Handbook is specific about a freeway breakdown: "be careful getting out of your vehicle. If possible, leave through the door away from traffic. Do not raise the hood", and "while you wait for help, stay in your vehicle with the doors locked." A raised hood blocks your own view of approaching traffic and does nothing your hazard lights are not already doing. Standing beside the car puts you in the most dangerous place on the road — the shoulder of a freeway is where drifting and distracted vehicles end up. The rest of the advice starts earlier: "at the first sign of trouble, begin to pull over", and "never stop in the driving lanes."
