Additional 3-Way Intersections and Intersection Signs If a side road enters from the left, the sign will display a horizontal line to the left of the vertical line. The Y-intersection is another type of 3-way intersection sign. It indicates that the junction ahead looks like a 'Y', as the name implies. These signs are required at intersections where three or more roads meet, such as at roundabouts and trapezoids.
4-Way Intersections Additional 4-way intersections require separate signs for each direction which meets the requirement. These directions may be indicated by color, such as red/green/yellow/black. Some states also use arrowheads to indicate certain directions in a 4-way stop sign system. For example, an arrowhead on a green sign means that traffic entering from the right must turn left at the next opportunity while traffic turning left can enter any opening in the center divider. This is similar to a conventional stop sign except that it does not have a red component.
Traffic signals Traffic lights are used at some intersections to control the flow of traffic into each direction. They are usually located at high-volume intersections with multiple lanes in each direction, but they can also be found at smaller intersections with only two ways in and out.
The purpose of traffic signals is to reduce accidents by giving priority to certain vehicles over others. They do this by allowing certain drivers through at a specific time while keeping other drivers waiting until the light turns green.
A three-way junction (or three-way intersection) is a three-arm road intersection. A Y junction (or Y intersection) typically has three equal-sized arms. A T junction (or T intersection) has three arms as well, although one of them is usually a minor road that connects to a bigger road. All types of junctions may have signs to indicate which direction traffic flows on each arm.
Three-way stops are used at these intersections, allowing drivers to make a safe stop without having to see all lanes of traffic at once. The concept was invented by Dr. Ernst Dickmanns of Germany who introduced it into his country in the 1950s. It is now used in many countries around the world.
In North America, three-way stops are most commonly found in rural areas where there are no traffic lights or signals of any kind. Instead, each driver at a three-way stop must yield to every other vehicle before making their own decision about how to proceed.
In urban areas with red light cameras, drivers fail to come to a complete stop at three-way stops and this violation results in a fine. However, cities vary on how strictly they enforce this rule. Some turn three-way stops into two-way stops by placing a white line down the center of the road, while others leave the stops as they are today. Drivers should use caution at three-way stops in order to avoid collisions.
Two-Way Arrow Traffic Sign Before turning right or left, yield the right-of-way or come to a complete stop. You cannot pass past the crossing without turning right or left. These signs are placed at crossroads and intersections to indicate that traffic may be moving in both directions on separate paths. Two-way arrows should not be confused with four-way stops signs which are used to indicate that all roads lead to an intersection where traffic can safely stop.
Four-Way Stop Signs A four-way stop is used to indicate that all roadways lead to an intersection where traffic can safely come to a stop. These signs are placed at crossroads and at locations where multiple lanes meet so that vehicles can proceed through the intersection only if it is safe to do so. Four-way stops should not be confused with two-way arrow signs which are used to indicate that traffic may be moving in both directions on separate paths.
One-Way Street Signs A one-way street indicates that traffic moves in only one direction along the roadway. This can be indicated by a "one way" sign above the entrance to the street or by painted markings directing traffic only in one direction. One-way streets are used when there is no such thing as a free turn for drivers coming from opposite directions but who are still within sight of each other.
