Final answer:
For a safe emergency roadside stop, activate your four way flashers before pulling over, shift to the proper gear, set the parking brake, and turn off the vehicle's engine before exiting.
Step-by-step explanation:
When making an emergency roadside stop, certain steps should be followed to ensure safety. Firstly, you should activate your four way flashers before pulling over to the side of the road. This notifies other drivers of your intent to stop and alerts them to your presence. Secondly, once safely off the road, you should shift transmission to the proper gear and set the parking brake. This prevents the vehicle from rolling.
Lastly, it is generally recommended you turn off your vehicle's engine when you exit. Leaving the vehicle running could pose a risk due to unattended operation, especially if in an emergency situation where you might be distracted.
