Agree BUT only if it reduces visibility massively, having them on in normal rain is a nightmare for following drivers (and will get you pulled by plod), as a professional driver I hate foggy mornings, not because of the fog, but because I know I am going be blinded by idiots who leave them on when visibility improves and then usually for the next 3 weeks
Highway Code
Rule 236
You
MUST NOT use front or rear fog lights unless visibility is seriously reduced (see Rule 226) as they dazzle other road users and can obscure your brake lights. You
MUST switch them off when visibility improves.
Law RVLR regs 25 & 27
And for those who have fogoton ( A lot of us I expect

)
Many of the rules in The Highway Code are legal requirements, and if you disobey these rules you are committing a criminal offence. You may be fined, given penalty points on your licence or be disqualified from driving. In the most serious cases you may be sent to prison. Such rules are identified by the use of the words
‘MUST/MUST NOT’. In addition, the rule includes an abbreviated reference to the legislation which creates the offence.
