Yes, because if it were correct you should go under ground. *MANDATORY* 
!!! ;-)

I did not say that your translation is bad and I don't blame you, I 
meant that the explanation in the Belgian highway code is bad.
*Actually*, this sign 
<http://wiki.openstreetmap.org/wiki/File:Belgium-trafficsign-d1_downleft.svg> 
and this sign 
<http://wiki.openstreetmap.org/wiki/File:Belgium-trafficsign-d1_downright.svg> 
are the only (direction) ones placed on obstacles.  The blunder of the 
code is that there should be two different IDs such as D1a and D1b, and 
two explanations for two different meanings (turn left and go around).
So, what should be done is split the D1 row in two, move those two signs 
to the second part and put each explanation in the correct part.
Who will do that?
Do you want it confirmed by a lawyer (source=)? I'd prefer.

The highway code has many blunders.
The "no parking sign" with a double headed arrow is described as "no 
parking over a long distance".  It's obviously meaningless to say "long 
distance" without saying how long and not to say *where* the 
interdiction applies.
The correct definition is  "... in front of the sign and behind it, up 
to a crossing or another signal.

E1 explanation should add "behind the signal".
One E1 in a GB parking lot was obviously placed to mean the opposite.

Nice page. I appreciate the SVG format.
Would you like some fills if I can find or make them?
I would replace B9 with B15 with the bars in all 6 directions :-)
I also like the left-turning D1 rotated 90° anticlockwise.
(I took a photograph of one with a Carrefour shop in the background)
Especially when followed by left-down-sloping rotated 90° clockwise.

Cheers,

André.
