The FIA has delivered its verdict following Nico Hulkenberg's investigation after the Sauber driver was summoned for failing to slow sufficiently under double yellow flags during first practice for the Belgian Grand Prix. After reviewing the incident, the stewards opted to hand the Audi driver a reprimand, his second of the season so far. The FIA's official document explained that the double yellow flag was triggered only after Hulkenberg had already entered the relevant marshalling sector and passed the stranded car, leaving him with no opportunity to react before entering the zone.
"The driver stated that he did not see any trackside yellow flags nor any yellow light panel and was therefore unaware that the sector was under double yellow conditions. However, the evidence showed that as the driver approached the apex of turn 6 a yellow flag warning was displayed on Car 17’s steering wheel and a green light panel was shown at turn 7."
"Following the dashboard indication, the driver lifted the throttle. He said he did this because he noticed the light on his steering wheel and saw the green light panel indicating the end of a yellow sector. He said that he did not know that he was in a double yellow sector but realised the sector was yellow from the light on the steering wheel and the green light panel.
"He said that there was nothing on track ahead of him which indicated a hazard. The warning light on the steering wheel was flashing. The Team accepted that this likely indicated a double yellow sector, a single yellow sector indicated by a solid warning light."
The stewards acknowledged that Hulkenberg had only a very limited opportunity to realise he had entered a double yellow flag zone, as the warning on his steering wheel appeared while negotiating Turns 5 and 6. They also accepted the German's explanation that he was unaware the sector was under double yellow conditions, although they noted he knew he was at least in a single yellow zone and could not be certain it was not covered by double yellows.
"The Stewards nevertheless accept that the driver had very limited opportunity as he negotiated the changes of direction through turns 5 and 6 and before he passed the green light panel to recognise that the light on the steering wheel was flashing to indicate a double yellow sector."
"Given the circumstances, the Stewards considered that the driver might be excused from not knowing that he was in a double yellow sector and accept the driver’s statement that he did not know. However, he did know that he was at the very least in a single yellow sector. Further, he could not know that it was definitely not a double yellow sector."
Ultimately, the stewards concluded that Hulkenberg's reaction of lifting off the throttle and reducing speed was not sufficient to meet the requirements of a double yellow flag zone. However, given the exceptional circumstances surrounding the incident, they decided that a reprimand was the correct decision.
"The reaction of the driver by lifting off throttle and reducing some speed was insufficient to conform with the expectations of a driver in a double yellow sector. Therefore the driver failed to comply. However, having regard to the exceptional circumstances described, the Stewards determined that a reprimand to the driver was the appropriate penalty."
A Ferrari investigation is still pending after the Italian team was referred to the stewards for an alleged procedural breach between the opening and second practice sessions of the Belgian Grand Prix. After FP1, Ferrari electronically declared the return of two sets of dry-weather tyres for both Charles Leclerc and Lewis Hamilton, but the tyres themselves were not physically returned to the designated supplier before FP2, potentially breaching Article B6.4.2 of the Sporting Regulations.
