Up early this morning to be able to take the dogs out for a walk, have breakfast, get ready to
be out of the door to have my first driving lesson in Telford at 7:15am. I don’t normally start
this early, 8:30 is a reasonable time in my opinion. But, Harriett had her test booked for

It was a bit foggy on the way, so as according to Rule 226 of the Highway Code I put my
headlights on, as visibility was less than 100 metres. I also put my rear foglights on. I
checked this when I got home as I thought that you MUST put your foglights on if visibility
was less than 100m. The rule doesn’t say that. It says you MAY put them on but MUST turn
them OFF when visibility improves!!

So here is the rule.

Highway Code Rule 226
You MUST use headlights when visibility is seriously reduced, generally when you cannot
see more than 100 metres (328 feet). You may also use front or rear foglights, but you
MUST switch them off when visibility improves.

The MUST means it is the law, and you can be prosecuted if you do not obey it.

The Driving Test got cancelled because of the fog, which was a big disappointment for
Harriett and the two other candidates that turned up. Harriett thought that the test should
have gone ahead, as did the other candidates, but the Driving Examiners thought there was
a safety issue.
