Does a Grand Prix always go ahead, rain or shine?
Yes, a Formula One Grand Prix takes place in all weather conditions, and the tyre manufacturers have developed treaded tyres which help to avoid the risk of aquaplaning. Nevertheless, the Clerk of the Course has the power to stop the event, if this becomes necessary for safety reasons. Apart from grip, the greatest problem in the event of rain is visibility, which is significantly reduced due to the spray thrown up by the cars’ tyres. In order to counteract this problem, the cars are equipped with a red light at the rear which must be switched on if it starts to rain.
