Which vehicles are not subject to the “No Stopping” sign in this situation?

Explanation

With plate 8.18 "Except persons with disabilities", sign 3.27 "No stopping" applies to all vehicles except motorized invalid carriages and cars fitted with the identification sign "Person with disabilities" (formerly "Disabled"). The exemption for taxis with the meter on covers signs 3.28–3.30 only, not 3.27, so taxis may not stop here (Rules, signs 3.27 and 8.18).
