61. Is there a speed limit for the race?

There is a speed limit on the pit lane, which is 60km/h for practice and 80km/h for the official race (60km/h for both races in Monaco). At the pit lane, electronic speedometers are installed. During an official race, if a car exceeds the speed limit while passing through the pit lane, the driver is usually penalized with a stopping penalty. If it's a practice session, then he will be fined $250 for every kilometer per hour over the speed limit. If the driver repeats the offense, the penalty will be more severe. In order to avoid speeding in the pits, teams generally install speed limiters on their cars. When a driver pushes the speed limiter button when entering the pits, the car will travel within the speed limit.

62. How are the cars weighed?

The inspector can weigh the car at any time and the weight must not be less than 600 kilograms, including the driver. The weighing equipment is installed at the entrance to the pit lane. During the practice session, a computer randomly selects some of the cars, and when the selected car enters the pits, a red light comes on in the pit lane and the driver must drive the car into the weighing area. If it is found that the weight of the car is not up to the standard, the driver has the right to ask for a 2nd weighing, and if the car fails the 2nd time, the driver will be disqualified from this race. After the official race, all cars must be weighed and those who fail to pass will be disqualified from the race.

63. What are the different flags that appear on different occasions during the race?

Flags that may appear during the race include:

Red Flag: Appears at the beginning or end of the race to indicate the end of the race, usually due to a major incident on the track.

White Flag: Stationary means there is a slow car on the track, waving means there is a slow car ahead or an accident car returning to the pit.

Black Flag: represents a penalty, usually a 10-second stop-and-go penalty. Drivers must return to the pits before the next lap, stop for 10 seconds and then return to the track.

Black and white flag: warns the driver that there is a mechanical problem and he must enter the pit immediately.

Blue Flag: Standing still means give way during practice sessions, swinging means give way immediately. For official races, a stationary flag means give way and a waving flag means you must give way or you may be black-flagged. The exit of the garage indicates an approaching car.

Three Blue Flags: Three consecutive blue flags indicate intentional or illegal obstruction and will result in a black flag.

Red Stripe Flag with Yellow Background: Stationary indicates oil or water damage to the track, waving indicates a slippery track, drive with caution.

Yellow Flag: Stationary indicates slowing down and overtaking is prohibited; swinging indicates slowing down and overtaking is prohibited and there is an accident or danger on the track.

Double Yellow Flag: Waving indicates that the track is partially or completely blocked, usually accompanied by a safety car or red flag. Overtaking will result in a black flag penalty stop of 10 seconds.

Green Flag: Indicates that the yellow flag condition has been lifted and the driver may resume normal speed.

Black and white chequered flag: Drivers passing this flag indicate the end of the race, sometimes it is flashed early due to the long race time or the complexity of the track.
