  ABSTRACT: This paper examines driver compliance with No Right Turn on Red (NRTOR) restrictions at eight signalized intersections in Minnesota, where six locations were equipped with pedestrian- or time-of-day-activated dynamic blank-out signs and two locations displayed conventional static signs. High-resolution video observations were used to quantify right-turning driver responses. Compliance was measured using two perspectives: proportion of compliant cycles and proportion of compliant vehicles. The results showed that static signs were generally associated with higher compliance, yielding 80.0% per-cycle and 92.4% per-vehicle compliance, compared with 60.8% and 87.1% for dynamic signs. Logistic regression models were further applied to assess statistical significance and to evaluate how NRTOR effectiveness compares with other geometric and operational factors influencing driver behavior.
