On a Formula 1 timing screen, first identify what a number measures: a full lap, one of the lap’s three sectors, or the time gap to another car. Then use the column label and sector colour to interpret it. A purple sector is the session’s fastest; green is that driver’s personal best; yellow marks a slower sector.
What does each timing number mean?
Lap time: one complete lap
A lap time is how long a driver took to complete a full lap. It describes that driver’s lap, not their position or the time separating them from another car.

Sector time: a split within a lap
Formula 1 divides each lap into three sectors. Each sector time records the time for that portion of the circuit, making it possible to see where a driver gained or lost time. A sector is a split of a lap, not a separate lap result. Formula 1’s glossary explains sectors.

Interval or gap: separation from the car ahead
An interval is the time difference between a driver and the car in front; it is commonly called a gap. It is a relative separation, not that driver’s lap time. Formula 1 defines the term in its official glossary.

What do the sector colours mean?
Colours compare sector performance, but green and purple answer different questions:

- Purple: the fastest time set in that sector overall.
- Green: that driver’s personal best time in the sector. It can be a personal improvement without being the fastest sector of the session.
- Yellow: a slower sector time.
These colour definitions are from Formula 1’s sector glossary. Read the sector’s column label first; a colour is useful only once you know which part of the lap it describes.

How should you scan a timing screen?
- Find the driver or row. Make sure you are reading the intended driver’s data.
- Read the column label. Determine whether the value is a lap time, a sector split, a gap or another measure.
- Interpret the number in that category. A lap time measures a complete lap; a gap compares a driver with the car ahead; a delta needs its reference time.
- Use sector colours only for sector columns. Purple and green compare sector performance in different ways, while yellow indicates a slower sector.
Timing information is a snapshot: positions and gaps can change, and an active delta depends on the session and display context. Don’t infer more than the visible labels and comparison reference support.

Why can timing screens look different?
The data arrangement depends on the interface. Formula 1’s 2019 description of its Live Timing app said its combined screen displayed each driver’s best lap, gap, lap time and tyre use, with a driver tracker for location context. That is a description of the app at that time, not a guarantee that current screens have the same layout.
Formula 1’s current F1 TV subscription page lists live timing, telemetry, tyre usage and driver maps among its features. Available features and access terms depend on the offer and territory, so check the page for current details. The official sources do not establish that every device, interface, session or plan presents the same columns or updates in the same way.
