We drive on the left as in England and Australia. All speed limits are in km/h, 30-50 for towns, 60 for suburbs, and 90 for major (A) roads and dual carriageways. I’ll happily cruise along the open road at a good clip, but we must always slow right down through the towns/villages, 50 km/h maximum. There are often kids, dogs, chickens, etc., kicking around in the streets. Also, if you see the tour guide braking, there’s a good reason – and you should break, too! Many Thais ignore the typical unwritten rules of road positioning and merging we are used to in the West. We’ll go over this in person so don’t worry. There is always a “sweeper” and a service vehicle to make sure any riders caught by a traffic light or water buffalo crossing delay do not get separated from the group!
