Auto-rickshaw and some taxi drivers in the Capital have threatened to go on strike from Thursday over the issue of installation of the global positioning system (GPS) device in their vehicles.

“Beginning from May 19 night, around 50,000 auto-drivers and 9,000 black and yellow taxi drivers will go on strike,” said Bharatiya Private Transport Mazdoor Sangh president Rajinder Soni on Tuesday.

The leader of a prominent auto-rickshaw union in the city said there was no such plan and “a few trade unions might force auto and taxi drivers into the strike”.

Mr. Soni, however, said autos would go ahead with the strike: “We demand that the Government bear the cost of the GPS device. We are not against the installation, but we will not bear the cost as suggested by the Government. We further demand a welfare board for auto drivers,” added Mr. Soni.

Some auto-rickshaw unions held a protest at Jantar Mantar on Tuesday against the Delhi Government's proposal of having the auto drivers pay for the proposed GPS device.
