Answer:
Level ground
Explanation:
When you are driving and the oil pressure light illuminates, it usually means that your car might have lost oil pressure.
Therefore, you should first pull over onto level ground (since being on incline ground may not let you take an accurate measure of the oil levels) and turn off your engine. Then you should wait for a few minutes on level ground and see if the oil pressure light is still on and the oil is still low, if it is, you should call a mechanic or a tow since driving with a low oil pressure can damage your engine.
