Road sign font - anyone know this one?

I would be interested to know what this font is, as seen here:

Is it a variant of Interstate, or am I wrong?

I'd be interested to know what these ones are.... all help much appreciated!


If it's UK, it's most likely Transport Medium or Heavy.

Except it looks like FF Din to me.

Hmm... possible, as it looks like a council-sponsored sign. Still, I think it'd not be FF DIN then but a generic DIN1451. Of course, one would need a caliper or a micrometer to tell the difference.

That is an ideal road sign with illuminated letters that designers must taken into consideration. It's viewable in the public and effective for business advertising.
