We arrived at 12.30.  At 12.50 they took our paperwork.  First you need an application form which are on a bench immediately on your left as you enter building 3.  This form just needs your name and today's date.  It has a number of boxes on it for the officials to tick as you pass through the whole process.At 1pm at desk number 1 a lady took my paperwork.  I gave her my expiring driving license, original passport and a copy of the id page and the latest visa page.  She highlighted the date of the visa expiry and the passport number. I gave her a copy of my yellow tabien baan but she didn't seem interested and just asked my wife if we still lived at the address on the expiring license, which we do.   No mention of the medical form which I had just in case.  No mention of a police/immigration report.  She  gave us the paperwork back and a card with a number on it and the time 1300 to 1400 which is the video time. She then send us upstairs.First into a room with three machines of sorts.  First put your nose up against a guide and she lights  a red or yellow or green light to the side which you have to see with your peripheral vision.  Secondly sit in a chair and press a pedal with your right foot.  After a few seconds a light comes on up a scale and you must asap press another pedal.  That checks your reaction time.  Then she points to red or yellow or green on a circle made up of coloured dots.  Finally a depth of vision test where  there are two white pegs in a box.  she pulls the left one back and with a control box you must move it forward until it is as close as possible to being level with the other one.  Before these tests she gave me a little folder explaining them in English.Next into another room for a little pep talk in Thai and she put on a very loud safety film which lasted about 35 minutes.    After that downstairs and when your name is called check  your details on a form before they are put on you license card and sign to acknowledge them.  Pay your money (555 baht for me) and sit down and wait for the photographer.  He was very efficient and 5 minutes later I have a new license good for 5 more years.
Sorry to have waffled on but I hope it helps someone.  This was Muang Khon Kaen near Sala Klang.

Last Friday my wife and I were in town so we popped over to the driving license centre to ask.  The very first thing he mentioned was a medical form which even their own website says is not necessary for a 5 year to 5 year renewal.  No consistency, rules made up on the spot.  We are going tomorrow and I'll report back.

I think the name is KR Printer Service.  The words are the English words, but written in the Thai script.

Don't give them any ideas!  Pray to the god of your choice that we all do not have to go back to Nong Khai.

I read it as Bus station 3, building 2, floor 2.  I'll pop up and have a look this coming week as it's very close to me.

A tad early, but has anybody heard of  a hotel/restaurant doing a Christmas dinner this year?  (except the Pullman, I'm a poor farang this year)

Well, it's hard to argue with that!
