When should hazard lights be used in Pennsylvania?

Hazard lights, also known as warning lights, are designed to alert other drivers to a situation that may require extra caution. In Pennsylvania, these lights should be used when a vehicle is stopped on the roadside or in an emergency. This helps to make other drivers aware of potential dangers and allows them to react accordingly.

Using hazard lights in these situations is essential for safety, as it signals that there is a problem that may obstruct the normal flow of traffic. For example, if a vehicle has broken down and is stopped on the side of the road or in an unsafe location, activating the hazard lights can alert oncoming traffic to proceed with caution. This is particularly important on busy roads where other drivers may not be expecting a stationary vehicle.

Other situations, such as simply driving under the speed limit, parking in a lot, or only using them at night, do not necessitate the use of hazard lights and could even lead to confusion or misinterpretation by other drivers. These alternative options do not align with the primary purpose of hazard lights, which is to indicate a situation that could pose a risk to traffic safety.
