Red Bull team principal Christian Horner has stated that 'fine margins' will dictate much of the Qatar Grand Prix weekend as track limit violations continue to disrupt drivers.
'Exceeding track limits' typically occurs when a driver places all four wheels beyond the agreed boundary, which is often the white line or the outside edge of the kerb.
When such an offence takes place at a location where stewards believe it may have provided an advantage, they can issue warnings and penalties - as we have seen numerous times in qualifying sessions in Qatar.
"It’s obviously a little too difficult," he told Sky Sports F1. "They’re dealing with a safety concern as well, so you’ve got to follow the guidance of the FIA on that.
"I think for the drivers, it’s incredibly difficult because they can’t see the line. So, they’re effectively on feel and judgement.
"That’s why there’s so many infringements going on because the margins are so fine."
