All cars must be fitted with a fire extinguishing system that will discharge into the cockpit and engine compartment. It must be operable by the driver and must function even if the cars main electrical circuit fails.
There must also be a switch to trigger the system from outside the cockpit. Its location on the bodywork is indicated by a red letter E inside a white circle.
There must be a circuit breaker switch in the cockpit that the driver can use to cut all the cars main electrical circuits. This is marked on the dashboard by a red spark in a white-edged blue triangle. There must be an additional switch that marshals can operate from a distance with the use of a special hook. This switch is located at the base of the cars main roll-over structure.
All cars must have two rear-view mirrors, whose size and location must comply with strict requirements. Drivers must demonstrate to the FIA the effectiveness of the mirrors by identifying special letter and number boards placed at various distances behind the car whilst seated in the cockpit.
Seatbelts are compulsory in Formula One racing. Drivers must wear two shoulder straps, one abdominal strap and two straps between the legs. These must comply with strictly specified FIA standards.
All cars must have a red light on the rear of the car in a specific location defined by the FIA regulations. The driver must be able to switch this light on at any time. This is usually done in poor weather conditions in order to make the car more visible to following drivers.
The cockpit of the car must be padded to protect the driver in the event of an impact. In particular, the areas immediately behind and to the sides of his head, and above and to the sides of his legs.
In order to easily extract a driver from a car in the event of an accident its seat must be removable with the driver in place and his seatbelts fastened. The seat must be secured by no more than two bolts, which can be released using a standard tool issued to all rescue crews.
