The two most important differences between U.S. traffic rules and foreign countries' traffic rules are as follows: Very heavy use of fully-signed, mandatory 4-way stop signs at intersections (rather than 2-way stops, yields, or roundabouts as in other countries) with priority to the first vehicle (priority to the right if two arrive at the ...

The stop sign is retroreflective and equipped either with red blinking lights above and below the stop legend or with a legend that is illuminated by LEDs. Unlike a normal stop sign, this sign indicates a two-way absolute stop, requiring other vehicles travelling in both directions to remain stopped until the sign is retracted. [citation needed]
Traffic regulations are conveyed in signs that are rectangular with the longer direction vertical or square. Additional regulatory signs are octagons for stop and inverted triangles for yield. Diamond-shaped signs signify warnings. Rectangular signs with the longer direction horizontal provide guidance information. Pentagons indicate school zones.

Where a stop has been determined to qualify, it is signed at all approaches to the intersections with a standard octagonal "Stop" sign, with a supplemental "All-Way" plate. Earlier editions of the MUTCD allowed supplemental plates specifying the number of approaches in an all-way stop, as in "2-Way", "3-Way" or "4-Way".
A flashing amber traffic light usually indicates you have a yield or stop sign as a redundant sign, while a turned-off traffic light usually indicates you have the right-of-way. In the UK and parts of North America, drivers simply treat the junction as being uncontrolled when traffic lights fail, giving way as appropriate, unless a police ...
At arterial junctions with relatively quiet side roads, traffic is controlled mainly by two-way stop signs which do not impose significant interruptions on traffic using the main highway. Roundabouts are often used at busier intersections in Europe because they help minimize interruptions in flow, while traffic signals that create greater ...
