13 Dashboard Warning Lights Explained: What They Mean and What to Do

There is always that super driver who knows all the dashboard lights and their meanings. Most people, though, are at least partially mystified by the blinking array of hieroglyphics that assail modern motorists. 

Don’t feel bad if you’re struggling with symbols, because many of your fellow drivers have the same problem. Knowing what they all mean is worthwhile because it can make a huge difference in staying on the road or calling a tow truck. This guide will help you decode your dashboard and tell you who to call for top-class towing services if you get the message too late.

Understanding Dashboard Lights: Why It Matters

Dashboard Response Times Can Run Into Weeks

Every driver likes to think their on-road response time is good when hazards present themselves. There is a colossal contradiction, though, when 1 in 10 drivers takes up to a month to respond to dashboard signals, while 34% take several days. This can lead to repair-delay costs of up to $200 a day and engine failure that can set you back upwards of $4,000.

Ignoring Dashboard Lights Can Cause Accidents

Dashboards warn you about almost every issue your vehicle faces, from maintaining stability to avoiding impending collisions. Lawsuits from other drivers and significant medical expenses can all be prevented by paying attention to dashboard alerts.

Understanding your dashboard means you don’t have to be a mechanic to stop problems. Familiarity with common symbols – many of which are self-explanatory – can elevate drivers to a position of responsible awareness.

The Top 13 Dashboard Lights to Know

The trick to not being overwhelmed by dashboard lights is never having more than one blinking at you. Swift action prevents a single onboard message from becoming multiple confusing signals. Any red light means something serious is wrong, and you should probably pull over immediately to figure out what’s happening or get expert help. Here are some of the most common warning lights:

1. Brake Warning Light 

One of the most critical dashboard warning lights, the brake light alerts you to potential issues with your braking system.
