are they allowed to go the wrong way round a island, this morning i was approaching a island, i looked to the right , and carried on driving around the island i did not see the ambulance at that time, as i am going round to take my exit , a ambulance came at me the wrong way, we both had to do a emergency stop, as did the driver behind me, i was very lucky the ambulance didn't hit me, so what i want to know is are they allowed to do that .
