Reduce your speed unless the risk of a collision is present
Yes Sound travel faster in fog because fog is made of dens air so molecules are close to each other and sound travel by disturbance in molecules it means molecules transfer sound wave by hitting each other . so they do it on faster rate and it travel faster ( same case for rainy day)
The criteria for sound to travel is presence of particles, sound can't travel in vacuum, it can in air, it can travel even better in water (you can hear roar of whales for huge distances), for example it can travel even better in metal (when you put your ear on a train rail, you can hear train from huge distances.) or just in steam (sound travels better in fog than in clear air, because water in the air is making the air thicker.)
Fog description is description of fog.
it is more difficult to see events ahead
The sound signal that you should hear when a power boat is in the fog is one prolonged blast at intervals of no more than 2 minutes.
A Fog Horn.
One prolonged blast plus two short blasts every two minutes. Explanation: Sound signals let other boaters know where you are located during periods of restricted visibility, such as extreme fog. If you hear the fog signal of a vessel you cannot see, slow to a minimum speed until you are sure there is not a risk of collision. One prolonged blast plus two short blasts at intervals of not more than two minutes is the signal used by sailing vessels.
