Middle lane - how did you know?

[Graasspp]

Who taught you to stay left unless overtaking on the motorway?

How did all these utter counts not learn this?

For me it was my dad who told me.

Aibu to wonder how this ignorance prevails daily?

The type of people that think nothing of pootling along in the middle lane also tend to be the types not to consider that HGVs aren't allowed in the outer lane.

@GrittyTunnocks ermmm yes, that's what I'm saying. When motorways merge, the lines change.

I think this is an example of what @TeslaTwat is saying. Using a PP motorway choice for an example. These two pictures are both on the M40. The one on the left is half way between junctions 2 and 3. The one on the right is just after the end of the slip road where junction 2 joins.

Notice the length of the white lines in the image on the right is longer than the image on the left. This is what signifies more danger and to take more care.

It doesn't, however, signify that you must or must not change lanes. It's just a warning symbol.

Exactly! 👏👏👏

When you get to the exit point you will see a solid line and chevrons separating lanes. These must not be crossed. I'll get a pic

I can read...and can furthermore understand, even though I don't do motorway driving.

Wish these were actual signs

To answer your original question OP, when I was growing up I always thought there was a 'slow' lane and a 'fast' lane, and you chose which one you wanted to drive in! Then when I was old enough to learn to drive I read the highway code and found out I was wrong. I do think I used to hear the lanes being referred to as slow or fast though, and that made me confused about them as a child.
