Warning Lights on Your Dashboard Explained: What They Mean & When to Stop Driving

Few things are more stressful than seeing a warning light appear on your dashboard especially when you’re unsure whether it’s safe to keep driving.

Modern vehicles are equipped with sensors that monitor almost every system in your car. When something isn’t right, your dashboard lights up to warn you early before a small issue becomes a costly repair.

Why Dashboard Warning Lights Are Important

Dashboard warning lights are your car’s early warning system. They alert you to problems involving:

Engine performance
Braking and safety systems
Electrical and charging systems
Cooling and lubrication

Ignoring these warnings can lead to breakdowns, safety risks, or severe engine damage.

2. Oil Pressure Warning Light
