McLaren fined for a technical infringement on Norris' car after opening day in Monaco

McLaren has been fined after Lando Norris’s car came to a halt during the second free practice session at the Monaco Grand Prix and could not be recovered using the mandated Clutch Disengagement System (CDS).

The FIA stewards ruled that the team had breached Article C9.3 of the FIA F1 Regulations, issuing a €30,000 fine, with €10,000 suspended for 12 months.

The incident occurred when Norris stopped on track and marshals attempted to activate the CDS—an emergency mechanism designed to allow a stalled car to be pushed away even when its hydraulics or electronics have failed. Instead, the system could not be used at all.

In their decision, the stewards outlined the full chain of responsibility and the technical reasoning behind the penalty. According to the official explanation: “The team admitted that for aerodynamic purposes it had placed transparent tape over the button that is required to be pressed to activate the CDS.”

This modification directly compromised the system’s intended function. As the FIA representatives explained—and as McLaren conceded—the taped-over button could not be operated by a marshal wearing gloves:

“This, in the opinion of the FIA representatives and admitted by the team, completely defeated the purpose of the CDS system, which is designed to be activated quickly by a marshal wearing protective gloves. The team conceded that it was not possible to break the tape and press the button by hand without the use of a tool.”

The stewards emphasised that the CDS must remain immediately accessible, because its purpose is to allow a car to be moved under VSC or local yellow conditions without escalating to a red flag. In Monaco—where recovery space is extremely limited—this requirement is even more critical.

The stewards also referenced the recent precedent involving Visa Cash App Racing Bulls at the Canadian Grand Prix, where a CDS failure led to a red flag. That earlier case resulted in a €30,000 fine, €20,000 of which was suspended.

Because that incident had already highlighted the importance of the CDS system, the FIA expected teams to be especially vigilant:

“The Stewards have determined to suspend a lower amount of this penalty compared to a breach of this same regulation at the previous event, because that breach, and the subsequent penalty, should have alerted all teams to the importance of the CDS system.”

The FIA confirmed that the following personnel were involved in the hearing: “The Stewards heard from the team Sporting Director and Technical Director Applied Engineering, the FIA Single Seater Sporting Director, FIA Technical Delegate, FIA Electronic Engineer and FIA electric and Hybrid Powertrain Engineer.”

This reflects the seriousness of the infringement: the CDS is not a marginal component but a critical safety system.

McLaren’s decision to place transparent tape over the CDS button was, according to the team, motivated by aerodynamic optimisation. But in doing so, they rendered a mandatory safety mechanism unusable.

The FIA’s conclusion was unequivocal: “The CDS did not function when the car stopped on the track.”

That alone constitutes a breach of Article C9.3. The taped-over button made the situation worse, because it prevented marshals from performing the required recovery procedure.

The final decision reads: “The competitor (McLaren Mastercard F1 Team) is fined €30,000, €10,000 of which is suspended for a period of 12 months subject to no further breaches of this regulation.”

The suspended portion effectively serves as a warning: any repeat offence will trigger the additional €10,000.
