Wouldn't make any difference, I live in Nonthaburi, and the motorcycles shortcut through the construction cones all the time. Wherever their motorcycle fits, they just ignore all danger and do whatever they wish, basically undertaking/overtaking vehicles in the construction zone, TIT. They even shortcut through construction sites where workers have access through the jersey barriers, driving right through the jersey barrier gap (3 foot wide gap), then to add even more insanity to the process, they go through the jersey barriers and sometime head against traffic.....all to save time taking the correct/legal path. Come to Chaengwatthana-PakKret39 where they are installing the new Pink Line extension to Impact Arena Muang Thong Thani, you can watch them do this all day, that's with a well manned RTP booth within sight (at the intersection).
