F1 Singapore GP Declared Heat Hazard; Cooling Systems Required
The Formula 1 race in Singapore is expected to be very hot and humid, so the FIA is taking steps to help the drivers.
They've classified it as a 'heat hazard.'
Teams must equip cars with a cooling system that sends cool fluid to a vest the drivers can choose to wear.
The FIA made this rule after some drivers faced health issues from the heat at a previous race.
While the cooling systems are required, the drivers can decide if they use the vests or not.
The drivers face challenging conditions.
FIA classified the Singapore Grand Prix as a 'heat hazard' due to expected high heat and humidity.

The minimum car weight is increased by up to 5kg.
