Tacho help needed

Driving along today and noticed solid line to the right … what does it mean ?

I think it’s end of week as the two lines is end of two weeks

Dead end 40 minutes ahead…

Should really avoid typing with my elbows…

Is that a little :frowning: emoji directly above it? Obviously means it’s all gonna go pear shaped somewhere in the next (aforementioned) 40mins! Or is it a new warning that there’s a low arched bridge ahead if your relying on your car satnav if driving a decker?

As been said end of week
