The UK stop sign - relatively new. It was different when I started driving in 1965.
The UK 'Give Way' sign. Again there has been a change in my motoring/cycling lifetime:
This is what they used to look like:
Others in this line (which might help answer query on the Ireland 'Yield Right of Way' include the sign for 'Give way to oncoming traffic -
Some poor darlings struggle with this one so the authorities sometimes help:
The equivalent for when you have right of way:
One I like. I wonder if there was ever one for ferrets:
Two adventures from my travels. The road signs for Ireland amused me. Not all that long ago I drove from Belfast, Northern Ireland (UK) to Shannonbridge, Republic of Ireland. At one point on my route the road ran along the border and you kept switching from one jurisdiction to the other. One could get confused with changes in the road signs but what certainly did not help was the fact that speed limits in UK territory are specified in miles per hour whereas in the Republic they are in kilometres per hour.
In the UK the only instance of flashing traffic lights is a flashing amber at pedestrian crossings which tells motorists that the pedestrians still have right of way but one can move off if there are no pedestrians crossing. But we do not have flashing red or flashing amber giving priority to one line of traffic over another. I recall on my second trip to USA encountering a solitary flashing red light and i did not have a clue as to what I should do. On my first trip driving around Cape Canaveral and Cocoa Beach, Florida I hadn't encountered this. On this second trip I was driving from Washington Dulles to Punxsutawny, Pennsylvania and got to the point where Interstate 70 meets US 30 at Breezewood and there was this flashing red traffic light. I needed to turn right on US 30 but was just unsure as to whether I should proceed. Eventually a motorist behind politely suggested I do something so after a last minute check for road cops I did move off.
Relevant point - we have no equivalent to turn right on red in UK. Also you are not supposed to overtake on the inside but thousands do it.
Cannot recall if we have the same traffic light sequence in respect of amber:
Red - STOP
Red and Amber - prepare to move off
Green - go (if road is clear)
Amber alone: prepare to stop.
Zebedee time.
