When driving on a dual-carriageway with surface spray, which headlights should you use?

When driving on a dual-carriageway with surface spray, it is essential to use dipped headlights. Dipped headlights provide sufficient illumination for the road ahead while also ensuring that oncoming drivers are not blinded by bright lights. This is particularly important in conditions with surface spray, as it can reduce visibility and increase the risk of accidents.

Using dipped headlights improves your visibility to other drivers and allows you to see less illuminated areas, helping you to navigate safely. In contrast, main beam headlights can create glare and reflections off the spray, negatively impacting visibility for both you and other road users. Meanwhile, there are specific situations for using fog lights, but they are not appropriate for general use on a dual-carriageway with just surface spray. Therefore, using dipped headlights is the safest and most effective option in this scenario.
