Max Verstappen called upon fans at the Dutch Grand Prix to behave better after qualifying was disrupted by two separate incidents of flares being thrown onto the track.
Orange flares have become a common sight at Formula 1 race tracks in recent times, especially at European events. But amid concerns over visibility and safety, organisers have clamped down on them.
Messages displayed at the entrances to the facility at Zandvoort this weekend told fans that flares are banned and asked them to hand in any they had brought with them. But it seems there were some who did not heed those warnings as dozens were spotted being set off in the stands.
