Do not overtake a car which is on its hot lap even if you are faster. You can only overtake the car in front if his lap gets invalidated. If an incident like this gets reported, it will result in a qualifying ban for the next round.
A blue-flagged Driver is not allowed to defend his track position against the lapping car and he/she should stay on his/her line. Intentionally holding up or defending against a lapping car may determine the application of a penalty or even the disqualification of the Driver by the Stewards. Drivers about to be lapped have to behave in a predictable way without sudden changes of direction. Drivers in front must not stay ahead of a lapping car within blue flag (1 seconds of) distance with the car behind closing in for more than one full lap. The blue flag distance is determined and indicated by the game on the player’s HUD and in-car safety device. The lapping car may use the flashing lights to indicate intention to pass or indicate the passing move.
Lapped Drivers are allowed to un lap themselves as long as they can pull away after passing the Driver that has a lap advantage. It is at the discretion of the car in front to facilitate the move. The car with lap advantage is not required to allow the lapped car back in front and the car behind has no right to attack the car in front unless the move is facilitated or suggested by the car ahead by using indicators, lifting the accelerator or keeping to one side of the track. Depending on the race format, each driver should be able to gauge the necessity of the un lapping maneuver
