What do you do if the oil pressure light illuminates while driving?

If the oil pressure light illuminates while driving, you should immediately pull over to a safe location and turn off the engine. Check the oil level using the dipstick; if it's low, add oil as needed. If the oil level is adequate and the light remains on, do not continue driving, as this could indicate a serious issue. Instead, contact a mechanic for assistance to prevent potential engine damage.
