The speed limit on the tollways is 120kph -- I haven't seen any speed limit signs on the motorway portion so am not sure, but I believe it is less - I'm guessing 110kph. But, to answer your question, whatever they can get away with.Originally Posted by Beachlover
As for hiring a car with driver, it does not guarantee the driver will drive slower. I and friends took one popular service to Bangkok. I was on the edge of my seat all the way - the driver was speeding, tailgating, and continuously switching lanes. My friend that booked the car said he had used them often, usually with much safer drivers. Whatever, I swore off using that service.
My last pick up at Suvarnabhumi by Image Limo was last May - the driver was inside waiting at the point where I exited Customs. Also, the many times I have used Image, the driver has always driven sensibly -- sitting in the back, I have not paid attention to the speed - so, like most people, may speed a bit, but not so much I noticed.
