Removing temporary traffic control devices with the flow of traffic vs. backing the work vehicle behind to remove the devices

New York generally removes traffic control devices against the direction of traffic. However, this procedure is possible by going with the flow of traffic if the removal operation is protected by a shadow vehicle with an impact attenuator and an arrow board directing traffic into the proper lane, as with a typical mobile or slow-moving operation. The state does not allow driving against the flow of traffic, but backing against traffic where necessary is permitted. The state is currently considering a change but prefers not to do anything that encourages expansion of mobile work instead of placing signs and cones. There is a problem with maintenance crews using mobile work zones set-ups where lane closure signing and channelization might be more appropriate.
