Is it okay to keep driving a vehicle if the check engine light is on?

We often hear people say that it is okay to keep driving a vehicle if a check engine light stays on, but if it starts blinking or flashing, then you have to take immediate action. While that advice may have worked out for some people, it has also caused severe vehicle damage to others. Even if you notice that other than the check engine light, your vehicle seems fully functional. Do not delay. Continuing to drive with the check engine light on can potentially cause serious damage and costlier repairs.

The check engine light a vehicle is an indicator that something may be wrong with the engine or its components. When the light is illuminated constantly, it typically indicates a less urgent issue, such as a faulty sensor or a minor emissions problem. In such cases, it's generally considered safe to continue driving the vehicle, though it's important to have it checked by a mechanic as soon as possible to prevent any potential damage or further issues.

When the check engine light is flashing or blinking, it signifies a more serious problem that requires immediate attention. A flashing light usually indicates an engine misfire that could potentially cause severe damage immediately. If your check engine light begins flashing, it is advised to pull over and have the vehicle inspected there or towed to a mechanic for diagnosis.
