I suppose the Road Tax sticker and the CTPL sticker on my car window mention the expiration date and not the start date?

Yes, the date in the center of the tax sticker is the expiration date.

Was afraid of that. Wife didn't mention it: three months ovedue now ...

May I suggest the CTPL sticker is thrown away as that has not been issued for a long time - only the Tax sticker should now be on the windscreen.

Tip : I personally get mixed up with the months written in Thai so to help my old brain I aways write the (expiry) date in English just above the Thai date and so is easily read.

Took care of things. Road tax was 4028 baht for a 4 door pick up from 2003 + 500 baht penalty because of three or four months late payment.

On Friday I will have my new sticker en CPLT document.

Roadworthytest cost 200 baht.
