Section 2B.04 Right-of-Way at Intersections
Support:
01 State or local laws written in accordance with the "Uniform Vehicle Code" (see Section 1A.11) establish the right-of-way rule at intersections having no regulatory traffic control signs such that the driver of a vehicle approaching an intersection must yield the right-of-way to any vehicle or pedestrian already in the intersection. When two vehicles approach an intersection from different streets or highways at approximately the same time, the right-of-way rule requires the driver of the vehicle on the left to yield the right-of-way to the vehicle on the right. The right-of-way can be modified at through streets or highways by placing YIELD (R1-2) signs (see Sections 2B.08 and 2B.09) or STOP (R1-1) signs (see Sections 2B.05 through 2B.07) on one or more approaches.
Guidance:
02 Engineering judgment should be used to establish intersection control. The following factors should be considered:
Vehicular, bicycle, and pedestrian traffic volumes on all approaches;
Number and angle of approaches;
Approach speeds;
Sight distance available on each approach; and
Reported crash experience.
03 YIELD or STOP signs should be used at an intersection if one or more of the following conditions exist:
An intersection of a less important road with a main road where application of the normal right-of-way rule would not be expected to provide reasonable compliance with the law;
A street entering a designated through highway or street; and/or
An unsignalized intersection in a signalized area.
04 In addition, the use of YIELD or STOP signs should be considered at the intersection of two minor streets or local roads where the intersection has more than three approaches and where one or more of the following conditions exist:
The combined vehicular, bicycle, and pedestrian volume entering the intersection from all approaches averages more than 2,000 units per day;
The ability to see conflicting traffic on an approach is not sufficient to allow a road user to stop or yield in compliance with the normal right-of-way rule if such stopping or yielding is necessary; and/or
Crash records indicate that five or more crashes that involve the failure to yield the right-of-way at the intersection under the normal right-of-way rule have been reported within a 3-year period, or that three or more such crashes have been reported within a 2-year period.
05 YIELD or STOP signs should not be used for speed control.
Support:
06 Section 2B.07 contains provisions regarding the application of multi-way STOP control at an intersection.
Guidance:
07 Once the decision has been made to control an intersection, the decision regarding the appropriate roadway to control should be based on engineering judgment. In most cases, the roadway carrying the lowest volume of traffic should be controlled.
08 A YIELD or STOP sign should not be installed on the higher volume roadway unless justified by an engineering study.
Support:
09 The following are considerations that might influence the decision regarding the appropriate roadway upon which to install a YIELD or STOP sign where two roadways with relatively equal volumes and/or characteristics intersect:
Controlling the direction that conflicts the most with established pedestrian crossing activity or school walking routes;
Controlling the direction that has obscured vision, dips, or bumps that already require drivers to use lower operating speeds; and
Controlling the direction that has the best sight distance from a controlled position to observe conflicting traffic.
