When engaging in the "Safety First" steps, what should you do after checking under the car?

After checking under the car, it is essential to get into the vehicle as part of the "Safety First" steps. This step is crucial because once you're inside the car, you can ensure your environment is safe and that you're ready to proceed with starting the vehicle. Getting inside the car allows you to check the interior for any potential hazards, secure your seatbelt, and prepare to assess the vehicle's controls and surroundings.

Starting the car at this point may not be prudent without first ensuring that everything is in place and that there are no safety concerns that could arise from doing so. Turning on the headlights or checking the oil level can be important steps, but they are not immediately necessary following the inspection underneath the car before you have ensured that the interior of the vehicle is secure.
