When vehicles are halted at railroad crossings at night waiting for a train, what should drivers do with their headlights?

At railroad crossings, particularly at night, it is important for drivers to maintain visibility without blinding other road users. The appropriate action is to leave headlights on low-beam. Low-beam headlights provide sufficient illumination for the driver to see obstacles and the surrounding area while ensuring that oncoming traffic is not dazzled. High-beam headlights can cause glare for other drivers as well as any train operators, which is why they are not the correct choice. Turning off the headlights completely would significantly reduce visibility and could create a dangerous situation. Using hazard lights only does not provide adequate illumination for the driver and may mislead other traffic about the vehicle's position on the road. Therefore, using low-beam headlights is the safest option for maintaining visibility while parked at a railroad crossing.
