The hazard button and the warning light have clear differences in functionality. The hazard button is mainly used to alert other vehicles while driving. In the event of an emergency or when a short stop is needed, the hazard lights can be quickly activated to warn other drivers. The warning light, on the other hand, serves broader functions—not only for warnings but also to indicate specific driving conditions, such as malfunctions or alerts.

In practice, hazard lights are generally used in more urgent situations, while warning lights can be used more routinely to provide reminders and guidance.

Understanding the differences between these two helps drivers choose the correct one in different situations, thereby improving driving safety.
