Is it Safe to Drive a Car With the Check Engine Light On?

In most cars, the Check Engine light is orange, but in some, it manifests in two colours; yellow and red. When it is yellow, that means the problem is minor, so the car is still driveable. But then, when it is red, the vehicle should be stopped immediately to prevent further damage.

In cars with the standard orange Check Engine light, it can be unnerving to drive the vehicle bearing in mind the possible consequences of damaging the car further. But what if you are in the middle of nowhere? It is safe to drive the vehicle with the Check Engine light on as long as it is not misbehaving in any way.

Because different issues can cause the Check Engine lights, it is recommended to use a computerised diagnostics scanner. Undoubtedly, the advantage of these gadgets is that they pinpoint the problem accurately, removing any guesswork. The scanners generate codes that are specific to several listed car problems.
