My advanced driving observer was tested herself during my lesson at the weekend to become a senior observer. The examiner asked her a question which was "There are 6 types of road crossings named after animals. What are they and how do they work?"
I knew zebra and pelican. She added in puffin (I've never heard of it) she was flummoxed by the other 3.
I'm just off to google and will report back, but wondered if anyone else knew.
NN - do I recall correctly that road / driver safety is your bag? Have you any ideas?
