In Reply: A frequent theme in police reports after a collision between a motor vehicle and an older pedestrian in our study was that the driver failed to notice the pedestrian until it was too late to stop. The prominent warning signs described by Dr Hill seem a well-intended step toward addressing driver inattention. Our study provided no direct evidence about how well such signs would work for preventing collisions, but it did suggest that not all well-intended interventions necessarily achieve their aims. We support Hill's call for studies of the effectiveness of attempts to improve signage and signalization at pedestrian crosswalks. Such studies might even use a randomized-trial design to minimize confounding.
