What are the rules for using DRS in F1 racing?

[LeKing]

Rules for using DRS in F1 racing: 1. Race lap count: It must be after 2 laps from the start, meaning it can be used starting from the third lap. 2. Track condition: The track must be under green flag conditions. 3. Time gap: The time difference between two cars must be less than 1 second. 4. Designated section: The vehicle must be in the permitted DRS zone. 5. Only for trailing car: Only the trailing car can use DRS. The following is an introduction to DRS: 1. Definition of DRS: DRS stands for Drag-Reduction-System, which in Chinese means a system to reduce air resistance. 2. Principle of DRS: When the car enters a straight, the driver presses a button to flatten the upper flap of the rear wing, reducing the downforce at the rear. This decreases the downforce on the car at high speeds, allowing air to flow smoothly over the rear of the car, thereby increasing speed.
