An angry Bulgarian biker shouted and hit a Thai motorcyclist after falling onto the ground to avoid a crash in Thailand.

Bulgarian ex-pat Tony Kalniev was making a vlog while riding an electric motorcycle when a local pulled out from a side road in Pathum Thani on Tuesday (December 8).

Helmet camera footage shows how Tony slammed on the brakes and flung himself to the ground to avoid crashing into the other biker.

He then confronted him while angrily branding him a "f***ing idiot" before a passing taxi driver intervened to separate the two.

Tony, who lives in the country with his Thai partner, refused to apologise for the outburst on Wednesday.

He said: ''Why should I apologise? I was hurt when I crashed. My bike was broken, not his. I saved him and his motorcycle by falling down for him, the stupid brain.

''If I was a truck he would have died. Instead of me apologising, the country should focus on training people properly to get a motorcycle or car license. A single day test is not enough to qualify people to be a driver.''

This is the shocking moment a motorcycle launched into an expletive-ridden road rage rant after crashing at a junction.

Bulgarian ex-pat Tony Kalniev was making a 'vlog' while riding an electric motorcycle when a local pulled out from a side road in Pathum Thani, Thailand, on Tuesday (Dec 8).

Helmet camera footage shows how Tony slammed on the brakes and flung himself to the ground to avoid crashing into the elderly man.

He then confronted him while angrily branding him a 'f***ing idiot' before a passing taxi driver intervened to separate the two.

Defiant Tony, who lives in the country with his Thai partner, yesterday (Wed) refused to apologise for the outburst.

He said: ''Why should I apologise? I was hurt when I crashed. My bike broke not his. I saved him and his motorcycle by falling down for him, the stupid brain.

''If I was a truck he would have been dead. Instead of me apologising, the country should focus on training people to properly get a motorcycle and car license. A single day test is not enough to qualify people to be 'drivers'.''

Footage of the bizarre incident angered locals who accused the Bulgarian of being disrespectful to his host country.

Noppadorn Koranat said: ''The foreigner was wrong to reach like that. Even though he crashed, he should not have been so abusive.''

Au Sorn added: ''People can't come to our country and tell us how to drive. He should understand our roads are different and not try to change people.''
