I rode a Yamaha Nuovo everyday in Hanoi for four years, so no stranger to crazy heavy no-rules traffic. I am planning on moving to Siem Reap in a few months and would like a definitive answer to the scooter question in town - I have seen posts that say expats not allowed to ride, too dangerous to ride, can ride if resident for three months, can ride no problem, can ride but watch out for tuktuk drivers etc etc. Is there anyone who can actually tell me the real story - for a start, is it legally ok?
