I witnessed an accident where someone stopped short in the left turn lane (which was waiting for the red to change) to wave someone coming the opposite way through to a gas station on the other side. The wave he meant was “I’ll wait here for you.” The wave she saw was “All clear go ahead and turn.” She turned, right in front of someone in the through lane and got hit. She then tried to blame the car that hit her saying the driver was speeding. I got involved as a witness and I know she ended up having to pay that driver’s damages. I’m not sure if she tried to go after the waving driver but that would have been the smarter move.
