What should you do when the oil pressure warning light illuminates?

When the oil pressure warning light illuminates, it indicates a potentially serious issue with the vehicle's oil pressure system, which can lead to severe engine damage if not addressed immediately. Pulling off the road and shutting off the engine is the appropriate response.

This action prevents further damage to the engine caused by inadequate oil pressure, which can lead to a loss of lubrication and possibly cause components to seize. It is crucial to stop the vehicle safely and turn off the engine to assess the situation without risking more significant harm. Continuing to drive could result in catastrophic engine failure and costly repairs, while checking the oil level while driving is unsafe and impractical. Ignoring the warning could have dire consequences for the vehicle's performance and overall health.
