For periods of lower visibility what must be done?

During periods of lower visibility, it is essential to reduce speed and increase following distance to ensure safety. Drivers should use low-beam headlights and avoid using high beams, as they can reflect off fog or rain, worsening visibility. Additionally, it's important to stay alert and be prepared to stop or change direction if necessary. If visibility becomes extremely poor, pulling over to a safe location until conditions improve is advisable.
