Clarkson, renowned for his outspoken remarks and acerbic attitude towards "political correctness", was suspended by the BBC on Tuesday (local time), with media reporting that he had thrown a punch at a producer following a row about food.
"I'm off the to the job centre," the 54-year-old presenter told reporters before getting into a car outside his home in west London.
Clarkson, a friend of Prime Minister David Cameron, was already on a final warning over accusations last year that he had used racist language while filming the show, the latest in a long line of incidents which had courted criticism.
BIT OF A DUST-UP
"He's been involved in a bit of a dust-up but I don't think it's that serious," co-presenter James May told BBC TV.
"Top Gear", aired in more than 200 countries and estimated to have a global audience of some 350 million, has become one of the BBC's most successful and lucrative programmes.
In an official statement, the BBC said the show would not be aired this Sunday and the corporation's news website said it was unlikely the other two remaining episodes would be transmitted.
The Guardian newspaper said that could leave the BBC's commercial arm, BBC Worldwide, facing a multi-million pound bill from foreign broadcasters for failing to deliver the episodes on time.
Meanwhile an online petition demanding the BBC reinstate Clarkson had attracted 442,610 supporters from all around the globe by Wednesday afternoon.
"The BBC will become irrelevant very quickly in the USA without Top Gear; be careful," wrote one signatory Fred Bertsch from Denver, Colorado.
"Jeremy Clarkson ist Top Gear!!!!" said Austrian Karl-Johann Reitmaier.
Clarkson became the popular face of Top Gear by mixing a passion for cars with blunt banter and swagger that has offended groups ranging from mental health charities and cyclists to Mexico's London ambassador.
The presenter and his employers have been forced to apologise on a number of occasions. He wrote in his Sun newspaper column in May that he had been told by the BBC that if he made "one more offensive remark, anywhere at any time, I will be sacked".
