Should you drive with your check engine light on? When you see the check engine light come on in your car, it can be tempting to just ignore it and keep driving. After all, the car seems to be running fine, so what’s the harm? However, there are a few good reasons why you should never drive with a check engine light. First of all, the light is there for a reason – something is wrong with your car. Ignoring the problem could lead to further damage, and eventually you may end up stranded on the side of the road. Second, if your car is emitting higher levels of pollutants than normal, it could have an impact on air quality. It’s always best to get the problem checked out as soon as possible.
