Yes, but only on the up hill stretches. In my opinion the is more
opportunity for lorries to overtake with a better speed differential on
the up hill stretches than on the level or the down hill parts. There
are only two lanes on the M11.
Aren't they usually up against the limiter anyway, unless it's a very
steep hill?
