How many times can DRS be used in racing?

DRS can only be used once after two laps from the start and within designated KERS zones. The DRS function refers to the driver's ability to control a flap on the rear wing from inside the car. This flap generates downforce during high-speed driving to ensure sufficient friction between the tires and the ground during high-speed cornering, preventing skidding or loss of control. F1 DRS usage rules: The trailing car can activate DRS when the time difference between it and the leading car is within one second (including the leading car catching up to a slower car). The trailing car can only use DRS in designated overtaking zones (DRS zones) on the track. Additionally, for safety reasons, DRS cannot be used during the first two laps of the race or for two laps after the safety car exits. The leading car cannot use DRS for defensive purposes, and DRS is prohibited under dangerous racing conditions (e.g., rain). DRS has usage restrictions and can only be activated under the following conditions: It must be after two laps from the start, meaning it can be used from the third lap onward. The track status must be under green flag conditions. The time gap between the two cars must be less than one second. The vehicle must be within a permitted DRS section of the track. Only the trailing car is allowed to use DRS. The original intent of DRS is to increase overtaking opportunities by allowing the trailing car to gain speed over the leading car. If the leading car were also permitted to use DRS, this measure would lose its purpose.
As a long-time follower of F1, I know that the number of DRS uses is not fixed but primarily depends on race regulations. During practice and qualifying sessions, drivers can typically use DRS an unlimited number of times—activating the system to reduce drag and boost speed whenever they enter designated zones. However, in the actual race, strict conditions apply: a driver must be within 1 second of the car ahead at the preceding detection point to activate DRS in the designated zones. Each track has several such DRS zones of varying lengths, leading to vastly different usage frequencies. On average, a driver might use DRS 5-10 times per race, but this entirely depends on their performance and tactical choices. I must emphasize that overusing DRS can cause instability or loss of control, so teams train drivers to activate it only at critical moments. For the most accurate understanding, it's best to refer to the official F1 rulebook or watch live broadcasts with commentary, as they provide real-time insights into specific application scenarios.
From my personal experience in racing activities, the number of DRS uses entirely depends on the actual driving situation. On the track, I always activate DRS when I'm close behind the car in front to overtake—it feels like instantly shaking off resistance, which is incredibly exhilarating. Typically, you can activate DRS once per DRS zone per lap, ranging from three or four times to over a dozen times in a race, but there's no strict upper limit. I have to be careful not to over-rely on it, as the car can easily skid or damage the rear wing. Remember, safety regulations require it to be used only in designated zones. During practice, I tested it several times without issues, but in races, you must follow the command system. I recommend beginners start with small track simulations to get familiar with the speed changes it brings and gradually master the timing. This not only improves overtaking skills but also avoids accidents caused by misuse.
