Junctions are often where road rage bubbles over, you can see the whites of the motorist's eyes, both of you edging to get out in front of the other. It's tense.
Well next time you find yourself in that situation, just think of this simple scenario created by the Royal Automobile Club of Queensland (RACQ), Australia which shows four cars - yellow, red, blue and black - waiting at a crossroads.
You'll never see the red mist again...maybe.
So let's get to it. Two of the cars facing each other have stop signs, another is faced with a give way sign, while the fourth - the black vehicle - has no such sign or markings.
Which one gets priority to turn right?
According to the RACQ, the correct order is black, blue, yellow and red. Obviously.
With the black car unobstructed by either a sign or marking, it should always get right of way to turn right and carry on its journey.
Blue then takes next priority with red giving way to its right - Aussie law - letting yellow go.
However, in the UK there is a slight difference and according to IAM RoadSmart, UK drivers don't always have to give way to the right, so if the red car was on the major road, it would generally get priority over the yellow.
Speaking to the Sun, Peter Rodger, IAM RoadSmart Head of Driving Advice, said: "The black car has clear precedence, with no give way line of any kind.
"Although many junctions effectively create one, we don't have a general give way to the right rule in the UK and I suspect that there will be regional differences in how we manage this situation.
"Which car goes second would generally be a matter of 'negotiation' between the drivers, with a tendency for it to be the blue car, because it has a straight path and is not turning across the path of another vehicle - an unwritten but largely accepted 'rule'.
"What happens next is where I think geography will alter the answer. In London, and possibly some other larger cities, the red car will be able enter the junction while the blue car moves through it, turning right immediately across its rear."
