An initial total of at least 50 of mytaxi's 17,500 drivers in London will be given first-aid equipment, including defibrillators. They will also be able to take first aid, CPR and defibrillator training in partnership with charity St John Ambulance.
Chris Phillips, former head of the National Counter Terrorism Security Office, will advise on counter-terrorism and security training as part of Knowledge+, with mytaxi also discussing its programme with the National Counter Terrorism Policing unit.
There are plans to roll the programme out to further drivers in mytaxi's network.
The news comes as London's black cabs sit atop the national news agenda, with the status of their rival operator Uber in the capital in doubt after the non-renewal of its licence.
The scheme has been launched today by Taylor Herring, producer of the below video, which includes several drivers, mytaxi's founder and members of the public. Teneo Blue Rubicon continues to provide PR and public affairs services to the brand, having been taken on last September ahead of its rebrand from Hailo.
A second video has also been created by Taylor Herring to illustrate the results of a survey of 1,300 taxi drivers, which finds one in four saying they have come to the aid of the public during a terror attack, and one in 100 have experienced a women giving birth in their vehicle.
