No, you do not need to use a strobe light when plowing. While some people may choose to have one installed on their vehicle for safety reasons, it is not typically necessary. Plowing requires the driver to be able to see clearly and safely navigate their route while avoiding any potential obstacles or hazards. The best way to ensure this is by having your headlights on during daylight hours and utilizing high beams in low-light areas. Additionally, drivers should always wear reflective clothing so that other drivers can easily identify them in the dark if needed.
