Formula One drivers are calling for a new safety device to be installed in their cockpits from 2017, hoping the so-called “halo” will prevent the lethal threat posed by flying debris.

Grand Prix Drivers’ Association (GPDA) chairman Alexander Wurz said yesterday that his members wanted “swift implementation” of the design initially suggested by Mercedes – a bar attached to the car that curves around the driver’s head and is supported in front by an upright strut.

Formula One has been testing various ways of improving head protection, weighing up the pros and cons of the halo compared with completely closed canopies, an option that some people fear could trap the driver in a crash.

The halo is designed to be removed quickly in such cases. Its backers say it does not significantly obstruct the line of sight.

“The research the FIA experts have done is very thorough and the process has brought forward a clear solution,” said the Austrian, who retired as a driver last year and now works on safety with the sport’s governing body.

“Now the drivers feel it’s time to implement the extra protection at the latest in 2017,” he told the BBC.

Improving head protection became a priority after the deaths last year of Briton Justin Wilson, who suffered head injuries from debris in an IndyCar crash, and Frenchman Jules Bianchi.

Bianchi, Formula One’s first driver fatality in 21 years, died in July, nine months after suffering severe head injuries at the 2014 Japanese GP when his car skidded off and hit a recovery tractor.

In 2009, Brazilian Felipe Massa suffered near-fatal injuries when hit on the helmet by a bouncing spring during qualifying for the Hungarian GP for Ferrari. He recovered and now races for Williams.
