Uncontrolled intersection

An uncontrolled intersection is a road intersection where no traffic lights or signs are used to indicate the right-of-way. Mostly, uncontrolled intersections are unmarked. However, in some locations, motorists may be warned by road signage or a warning light. They are found in either residential neighborhoods or in rural areas.

Uncontrolled T-intersection

At an uncontrolled T-intersection (3-way intersection), right-of-way rules differ from country to country. In the United States rules differ from state to state. In Australia and the United Kingdom, traffic on the terminating road must give way (yield) to traffic on the continuing road. In Germany,^[1] traffic generally has to give way to traffic on the right at an uncontrolled intersection, whether it is a 3-way intersection or not.

Uncontrolled 4-way intersection

At uncontrolled 4-way intersections, traffic is commonly required to slow and give way to any traffic on the right in countries which drive on the right, and slow and give way to traffic to the left in countries which drive on the left. Common practice dictates that drivers will treat the intersection as if they have a give way (yield) sign and look both directions for cross-traffic, to avoid any accidents with motorists who did not recognize or did not follow the uncontrolled intersection rule.
