When you are banned from driving, you no longer have a driving licence to convert. In the UK, your licence is taken off you by the court and sent to the DVLA for destruction. Same in Australia. In both cases, when your ban comes to an end, you have to apply to get a new licence issued to you. Your banned driver mates, when they go to the Thai DMV to convert their driving licences are basically lying by telling the Thais they have a licence. They don't have a licence anymore when they are banned. Lets see what happens when they get in a crash and the police start snooping around. And Interpol has nothing to do with this. Driving licensing agencies talk to each other. And probably the Thais don't check at the time, but that comes down to the morality of the person applying for a driving licence. But then, if they have been previously banned for drink driving, drug driving, dangerous driving etc, they lack morals anyhow. So not surprised if you know people like that. They walk among us.
