First & foremost, do not sit close to the steering wheel! I have seen accidents where people have been severely injured by the wheel, ( Fact) do not drive close to someone in front! if they stop, can you?, ( Fact) Use your dipped lights + rear fog lights & remember to switch the bloody things off when the fog is clear, do not think IF the fog clears that it has, I have seen people ter@rsing after a fog patch only to be caught out by driving into another patch, keep your distance from the car / HGV in front of you otherwise you could end up underneath the HGV trailer, If you are on a Motorway & you know the area well, keep in the lane that you would use when you know your Junction is coming up, To you and a lot of people out there, Fog can dissolution you make no mistake about that, I've been there just like many HGVs drivers that use the motorway everyday, Lastly, don't think that it WILL not happen to you! a lot of people think like that, The results? The selfish B@STARDS never see their families or in-turn cause other people never to see their families again? DEATH! Is it worth it? I don't think so. If you drive with, "WHAT IF" in your mind you will not go far wrong. Safe Driving.
