Emissions Test

[smedly]

I have noticed many people talking about the emissions test when going through the legal green book application process, my bike a fuel injected 1100 honda is coming up for it's 5 year inspection next year, will this be a problem if so how to get past the issue

[LivinLOS]

If its already plated the 'test' is near non existant.

[Richard-BKK]

I'm not sure when the new rules go into effect, but if they already are the new rules, your vehicle exhaust emission cannot be more than the original specifications. Also a killer for re-inspection is oil leakage, and motorcycles are in the new rules not allowed to make to much noise.

So aftermarket modifications like Powercommander, mufflers, etc... are probably not a good idea (under the new rules of course)

But surely the 'on the ground' real world aspects of this is that these supposed tests, will be performed by the normal Thai garages that perform checks (ones with a gearcog displayed) for owner transfer and annual tax ?? and the current checks in 9 from 10 of them seem to be 'pay 100 baht please' you've passed.

Unless the checks are performed by a different system of controls, with a incentive to fail, I doubt this would change ?

[Richard-BKK]

The incentive for failing is that it will cost you money to get the motorcycle in original specifications to do the test again at the Department of Land Transport. Also, it is said, that only a few motorcycle dealers/garages per province will be selected to do this tests for the Department of Land Transport.

And the exhaust emission tests are not only for motorcycles, it includes all motor-vehicles on the public road. And, as everything is going to plan, the pollution control "police" guys will setup road blocks throughout the country – people in Bangkok are probably familiar with this road-blocks for emission test, but currently they only include trucks, touring-buses and public buses – they soon will include all motor-vehicles if everything is going to plan...

And you can find the catch, if an authorized emission test center have just approved a motorcycle and the day after it's found of not passing the test it can be a problem for the test center...

just been on a 3800km roadtrip in LOS, and passed 3 emissiontests. pickups as new as 2 year are now tested.

For OP, I would do the 5 year test in an authorised garage, and stay away from LTD. If failing in LTD, its gonna cost. Just think how easy to fail, cat not warm enough, fail.

Pollution control is in LOS already, soon in all provinces at every test and in roadblocks. Sorry, reality

[Richard-BKK]

For Smedly, it's important to know that his motorcycle doesn't need to pass the current “very strict” exhaust emission standard. On the other-hand, it will need to be within the rules for decibel (noise) production and if the motorcycle leaks fluids its “red-card” straight away...

Two-stroke motorcycles who have exhaust condensation, in which a substance of water mixed with oil comes in liquid form out of the exhaust pipe can forget passing the pollution test.

I have no confirmation that they currently are using the new rules, but even under the old set of rules your motorcycle only needs to meet the exhaust emission of the moment the greenbook was issued.

hi, this is some topic that i found interesting.....so i would like to know. I have a 25 year old virago 750 , just fixed it up . It has a clean green book and plates , 100% legal . When Ownership was changed there was no look or check on emissions at all...they looked and checked both nrs (frame & engine) and took photo of the Bike....so when does this emission control, if at all?

About noise...i got a new custom made exhaust for the virago 750...gives some crazy sound and those are measured where and how often?

Thanks for the info,

[Richard-BKK]

The thing is that its not the age of the bike that is important, it is the date when it received its greenbook what is important. So if your Yamaha Virago 750 received its greenbook 25-years ago I would be surprised if they had any data on emission rules of that time. For noise I think most Thai LTD officials know what is too much and what is okiedokie.

On Phuket every village has a test center.. Maybe thats different elsewhere but its the reality I see.. And none of them except the one next door to the LTO do any kind of test.

Also are you really suggesting that once initially tested and given a green book, every bike will need to constantly pass the same Euro III type emissions test ?? Including all the 2 strokes and carbed bikes on the road ?? Thats what your claiming yeah ??

Where I am any bike older than (I think) 5 years must have a test pass paper if it is being name transferred, or taxed, and presumably when moved provinces..

If you pay a local testing garage to do the paperwork the 'test pass' is included in the fee, they dont even look let alone fail.. If you go do it yourself the test is done properly, but I still have yet to have any vehicle fail, tho I did see them stick the emissions reader in the exhaust of my scoot and put a microphone a few feet from it.

[Richard-BKK]

Okay I will try to explain it childlike simple – if your motorcycle received a greenbook in 1999 it will need to pass the (pollution) emission rules of 1999. If your motorcycle received a greenbook in 2009 it will need to pass the (pollution) emission rules of 2009.

So if your motorcycle is from 1999 it will pass the emission test, as in 1999 there-where no emission rules for small size combustion engines.

And again, I have no idea if the new rules are being used, or if they are going to be implemented... And I not suggesting anything – I try to share my knowledge with people on this forum, what is of course a stupid idea, so for everybody you will know about the new rules when they are being presented to you. Not expect any new messages about the subject from me.

[LivinLOS]

Ahh ok..

So it isnt the full strict Euro III.. Secondly I simply cant believe we are going to see police, at roadside blocks around the country, doing checks, with a data set of what every years output should be, testing bikes to those levels. Its simply too complex for them to handle.

They are doing it for the last two years for trucks, buses and other large vehicles **, its amazing but they use some new technology called a computer. And they not need to know every model of motorcycle, they only need to know which year the greenbook was issued. Because the day that the greenbook was issued is the DAY/MONTH/YEAR that the vehicle's emission rules need to pass.

Anyway – the discussion here turns in another example of people trying to misinform a person asking for advice – and if somebody comes with a warning that things could be different or changed over the last few months (since April 2010) than they don't accept it or even trying to discredit it.

** katabeachbum claims that pickups as new as 2 year are now tested.

p.s. I will, if I can find the time, will publish the new exhaust emission and pollution rules and follow-up testing for small combustion vehicles proposal on my website. Than you can read and discuss it to the end of time...

thai emission requirements for bikes are stricter than EuroIII, and on some points stricter than California which used to be the most strict in the world.

The new (for LOS, been around in EU and US for a while) roadside equipment for noise and emision is online with GSM, they enter your VIN, enter sensor in exhaust and microphone close to exhaust. Engine rev to high rpm. Screen says fail or ok.

As said, so far only around BKK, but its coming as they recieve more equipment. Friday 23rd July complete roadblock on HW4 from Hua Hin to BKK, every pickup more than 2 year old and larger diesel checked. Many failed.

there was one on the 22nd too in Prechuap, but I didnt stop to look and wasnt pulled over, my PU is less than one year

When the BiB have a new toy that ensures plenty of tea money coming in, it will get used extensively.

Curios...what happens when a motor fails the test?.....instant fine? Instant impounding? date to have rectified and rechecked by?

Its a good incentive for keeping your bike exhaust standard now.

Going to be many very cheap 2 stroke bikes available soon.

But it will be welcome if it cuts down the clouds of black desiel billowing out of buses and trucks that u get to ride behind at times. I wear a yellow jacket for safety reasions and after one week of commuting to work its black. Always wonder what colour the insides of my lungs are.

Interesting.. As I was informed in 2 ways that the year the greenbook is issued isnt recorded in the greenbook (unless of course its the first one) ?!?!

I have a 95 bike model.. Thats pre the 97 excise tax problems.. When there was a phuket swoop on the unpaid excise bikes a or year or two ago, I had a large fight with the DMV / Customs as they claimed the bikes 'manufacture' year as per the book, isnt necessarily the year it was imported and registered. Hence they argued I should prove when it was imported to ensure it wasnt imported post 97 (impossible if you have only a normal green book) they took the guilty until innocent line.

Incidentally they did exactly the same with a mate (who ended up paying the bribe to get it back, I had better connections to negotiate for me) and their demand to him was "bring us the first book the bike was issued" to prove its initial registration date, again impossible to a current owner many years later as they keep the old book when they issue a new one.

So where in the green book does it state initial registration year as opposed to year of manufacture of that model ??

What next? They've turned all the highways into Bangkok into speed traps, now this silly smog testing? Give them another few years and they'll be as petty here as the California b*stards I came here to here away from.

First of all, I'm talking here about a new set of rules, which we still do not know if they are implemented. Maybe you need to read back the thread a bit. I know for a fact that the Department of Land Transport know exactly when the greenbook was issued. They can even, as in magic get the original file on the desk if you have an issue. How do they do it, maybe one of Harry Potters friends, or maybe the greenbook number has something to do with it, what do you think?

Second we are discussing emission rules which is controlled by the Department of Land Transport, the issue of 'excise tax problems' is something the Thai custom/revenue department control, and the Thai Revenue Department has not access to the information of the Department of Land Transport. (Maybe, but that probably will change also).

For me it's easy to say I not know all answers, but for you it seems to be impossible to amid that you could be wrong saying “If its already plated the 'test' is near non existant.” to the OP.

Well its precisely that information, that the LTO, and the customs dept, clamed they were unable (was impossible) to get. The initial import dates and paperwork relating to its initial taxation / registrations.

(Maybe, but that probably will change also).

No but I used an experience of my own, with the LTO, over a similar issue, to show you that they could not provide the information (even with weeks) that you seem to think they will have at their fingertips at the roadside.

For me it's easy to say I not know all answers, but for you it seems to be impossible to amid that you could be wrong saying “If its already plated the 'test' is near non existant.” to the OP.

And as of now.. I stand by that statement.

Right now, if its already plated, your chances of having any form of emissions test that they fail you on, is near zero.

This may (or may not) change in the future.

roadblocks, so far fines only

LTD, go home and fix your bike, or new emissiontest at 29k +++ required in BKK area. Up to LTD official

Instant impounding on noise has happened

And most bikes were not brought here spanking new (my bikes age verified by frame number traces and model history)

Reg plate agreed

Page 5 only shows the first person 'in this book' doesnt show the first Thai owner unless thats the only book its ever had. Simply asking for a replacement book puts you on this spot.

Place 9 is blank on mine.

I only have one book with me, as I am travelling, not sure how it is with the other bikes I have. But this still doesnt give me a date it was brought into Thailand, the best it can do it do is go back as far as the current book history.

[powderpuff]

I have had 5 motorcycles & 1 car.

each & every year when I renew the car (after 5 years) a probe gets stuck into the tail pipe.

Dozens of inspections done on motorcycles - probe never not once into tailpaie.

These are the old rules.

Again I would echo what LivinLOS said.

Based on the age of your motorcycle - you should be golden.

As to loud mufflers - keep a spare handy for inspection day.

[JonnyF]

Not being cynical but no matter how good the intentions are, this law will quickly become another way for a group 6-10 cops (complete with shades, clip boards and face masks) to demand 200 baht.

If you're not deemed to be speeding, in the wrong lane, visor too dark etc. then now they can throw this at you. If you fail the test will they print the results and allow a retest/appeal? Or can they just stick a sensor in the exhaust for 20 seconds and then say "Solly, no good"? I'm guessing the latter.

You can try to jump through their hoops or just keep 200 baht in your pocket and ride what you want where you want, how fast you want etc. I choose the latter and so far it's cost me 1400 baht in 4 years. If I didn't sacrifice my time arguing with them a few times it would be around 2000 baht. So that's about 7-10 UK pounds a year not to worry about it.

My 2006 TMax came with a replaced book, and yes I appeared as the first owner in this book page 5, but page 4 first position was 16 years old, date of issuing first book. First owner could be found in LTD computer, but it took someone from the gouvernors office to wanting to find all info in LTD computer. Its there, if forced to reveal.

In your case customs? possibly wanted to shade all info

Anyway, a simple entry of VIN (as on frame and tax sticker) reveals all info needed to know emission requirements for every single bike in LOS.

Dont know their speed of investment for on road equipment, but with the speed of purchasing photoboxes and lasers for speed control, I am afraid it wont take long. Fortunately all byrucrats believe only 300k people live in Phuket, so we will be last:)

Edit Position 9 page 4 blank, usually indicates bike is build from (imported?) parts, IOW no model year. A frame without VIN position #10 indicating modelyear, as most japs and LOS bikes, has per def no modelyear. Some ad modelyear anyway, some dont, most ad a more recent modelyear than actual bike. Up to seller/first reg

Edit again. My advice for OP, assuming his bigbike has a only 5 year old book, is still to have it approved at an authorised test garage and stay away from LTD. Older bikes/books, no problems on emmision so no checking

OK, well using a known bent book may not be the best reference. But it would seem on mine its year of manufacture not year of first reg, or they believe my bike was imported as parts new !!

Agreed on hiding info, they were being money grabbing cnuts.. they denied the ability to determine this, both boss of the LTO and customs offices. It wasnt only me, there was lawyers involved etc on many harley guys too.

Well the fact they dont seem to be able to introduce even a fining system for passenger helmets on Phuket means it possibly will take a while.

An just more evidence of how sloppy the whole system is.. Someone posted clear proof how a previous book had page 18 excise tax information in it, and a new issued book they just didnt bother to move that over. And of course that lazyness on the part of the LTO, because its not important at the time, creates a 10's of 1000 baht bill for a future owner when they retrospectively apply laws no one bothered with in the past.

I tend to think this is going to be a non issue for the next few years even. Its certainly a non issue now IMO.
