What is the recommended practice for using headlights in low visibility situations while responding to emergencies?

Using low beams in low visibility situations while responding to emergencies is the recommended practice because it reduces the risk of blinding oncoming drivers. High beams can create significant glare that may impair the vision of other road users, potentially leading to dangerous situations. Low beams provide sufficient illumination of the road without reflecting off fog, rain, or snow, which could reduce visibility even further.

This approach balances the need for the emergency vehicle operator to see well and navigate safely while also considering the safety of other road users. Flashing headlights intermittently or using only sirens does not provide effective visibility or necessary communication to other drivers about the emergency vehicle's approach. Therefore, utilizing low beams is the safest and most effective strategy in such scenarios.
