How Formula 1 Sets the Starting Lineup When Multiple Drivers Begin from the Pit Lane

Why Drivers Are Sent to the Pit Exit

A pit lane start is one of the heaviest sporting penalties in Formula 1. Instead of lining up on their assigned grid slot, a car must begin the Grand Prix from behind the pit wall. This can happen for technical breaches, such as altering suspension settings or installing different component specifications once parc ferme rules take effect after qualifying. It also occurs when teams exceed seasonal power unit component allocations, fail to depart the pit lane thirty minutes before the formation lap, or leave mechanics touching the car past the 15-second pre-race signal.

Establishing the Order at the Pit Exit

When several competitors must start from the pit lane in the same Grand Prix, race officials cannot allow them to race down the pit lane to claim track position. Instead, the F1 pit lane start order when multiple cars start from pits is governed by sporting regulations under Article 42.3, which establishes a strict hierarchy based on qualifying and accrued penalties.

For drivers with 15 or fewer grid penalties, stewards calculate a cumulative grid score by adding their qualifying position to their penalty count. The driver with the lowest combined score lines up first at the pit exit. If two drivers share an identical cumulative score, their original qualifying lap time breaks the tie, giving priority to the faster qualifier. Competitors who carry more than 15 grid penalties do not receive this priority and are placed behind anyone with 15 or fewer penalties.

Formation Laps and Late Arrivals

Cars scheduled to start from the pit lane are required to complete the formation lap behind the grid before steering into the pit lane to take their assigned positions in the queue.

A separate rule applies if a car runs into trouble right before the start. If a driver spins or stalls on the formation lap and fails to regain their position before the first safety car line, or enters the pits after the formation lap is already underway, they forfeit any ranking calculation. Late arrivals simply join the queue at the pit exit in the exact order they arrive.

The Green Light Release

Once queued at the exit, drivers must wait with their engines running. When the main start lights go out on the grid, pit lane starters cannot immediately pull away. They are required to remain stationary until the entire field has passed the pit exit. Only after the last car on the track has gone by will race control switch the pit exit light to green, releasing the queue into the Grand Prix.
