Why Kerbs of Formula 1 track is white and red in colour? - Explained

Formula 1 tracks are known for their distinctive kerbs—those raised sections lining the track, typically painted in bold white and red. While their eye-catching colours grab fans' attention, their role in a race is far more complex and crucial for drivers. These kerbs act as both a challenge and a strategic tool, determining how drivers navigate corners and push their cars to the limits. But why are they mostly painted in red and white?

Why Red and White?

Most Formula 1 fans think that the iconic red-and-white colouring of the kerbs serves the practical purpose of providing high visibility to drivers, especially in high-speed situations where split-second decisions are critical. In some cases, like at Monza or Brazil, the kerbs might reflect the colours of the host country’s flag, adding a touch of national pride to the track design.

However, the real reason behind this is a sponsorship deal between Formula 1 and the cigarette company Marlborough. In the 1970s Marlborough sponsored the Kerbs and gave it their current colour scheme i.e. Red and White. Despite the end of the contract due to its iconic value among fans, the colour scheme remained the same.

Role of Kerbs in defining track limits and strategy

In Formula 1, kerbs are primarily there to define the track boundaries, preventing drivers from cutting corners and gaining an unfair advantage. The classic red-and-white stripes are more than just aesthetic; they signal the limits of where a driver can push their car before risking a penalty. Beyond this, kerbs provide drivers with an opportunity to shave off milliseconds from their lap times by riding them strategically.

Not all kerbs are created equal, though. Some, like the painted or standard kerbs, can be used to a driver’s advantage. By riding over these kerbs—especially at the apex of a corner—drivers can maintain a tighter line and potentially increase their exit speed. This technique, known as "kerbing," can be the difference between winning and losing precious time.

The Danger of Sausage Kerbs

However, not all kerbs are friendly. Some, such as the infamous "sausage kerbs," can be brutal. These kerbs are designed to punish drivers who misjudge their line, often causing damage to the car’s suspension or floor, and in some cases, even launching the vehicle into the air. Several incidents, like Dennis Hauger's crash in 2022 and Alex Peroni’s terrifying launch at Monza in 2019, underscore just how dangerous these kerbs can be.
