Perez handed Monaco drive-through penalty as Russell escapes sanction

officials deemed his machine out of position when the lights went out. The Mexican had climbed to 14th through the opening corners, but serving the punishment dropped him toward the back of the field, rejoining just ahead of Cadillac team-mate Valtteri Bottas in 18th. He also faces a post-race FIA investigation for an alleged practice start infringement.

In Monaco, track position is everything. With overtaking virtually impossible around the narrow streets, a start-line penalty can ruin an afternoon and put enormous pressure on strategy. The contrasting rulings on Perez and Russell also highlight the fine margins stewards apply when policing grid slots, a recurring flashpoint throughout the season.

The details:

• Stewards ruled Perez's car was not properly within the grid box when the lights went out, triggering the drive-through penalty.
• After briefly climbing to P14, Perez served the penalty and fell to P18, rejoining directly ahead of team-mate Bottas.
• The FIA will investigate Perez after the chequered flag for a separate practice start infringement from earlier in the weekend.
• Russell was noted for a potential issue, but no further action was taken after officials confirmed his Mercedes was within its slot despite being angled slightly toward the center of the track.

What's next:

With overtaking nearly impossible in Monaco, Perez must now pin his hopes on attrition or safety cars to salvage points. The post-race investigation could also bring further penalties affecting future rounds. For Russell, avoiding sanction preserves his race plan and keeps the Mercedes constructor championship fight on track.
