If a driver experiences engine failure, what is a recommended step to take after coming to a stop?

Answer: B — Call for roadside assistance

When a driver experiences engine failure and safely comes to a stop, calling for roadside assistance is a crucial step. This action ensures that a professional can assess the situation, provide necessary repairs, or tow the vehicle if needed. It prioritizes safety, as handling a breakdown can be dangerous without the right tools and expertise. Turning off the engine immediately may not always be the best initial response, especially if the vehicle has not yet come to a complete stop or if there are other safety concerns. Exiting the vehicle immediately isn't advisable unless it's safe to do so, as it may expose the driver to oncoming traffic or other hazards. Checking the fuel level could be part of troubleshooting, but it does not address the immediate need for assistance or safety once the vehicle is stopped. Thus, reaching out for help is the most prudent course of action in the event of engine failure.
