Start/Finish Straight

The Start/Finish Straight is the main straight section of a racetrack where races begin and end, typically featuring the starting grid, finish line, and pit lane access.

This straight section serves as the most important part of any racing circuit. When you watch a race on TV, the Start/Finish Straight is usually where you see all the cars lined up in rows before the race begins. This lineup is called the starting grid, and the fastest drivers from practice sessions get to start at the front.

The finish line is painted across this same straight, marked with a checkered pattern. When the race winner crosses this line, officials wave the famous black-and-white checkered flag to signal the end of the race. Every time drivers complete a lap during the race, they cross this line, which is how lap times are measured.

Most racetracks position the pit lane alongside the Start/Finish Straight. The pit lane is where racing teams set up their garages and where cars come for tire changes, fuel, and repairs during the race. A concrete wall called the pit wall separates the racing surface from the pit area, and team members often hold up signs to communicate with their drivers as they speed past.

The Start/Finish Straight is usually the longest straight section on the track, making it a popular spot for overtaking. Drivers can use a technique called slipstreaming, where they follow closely behind another car to reduce air resistance and gain extra speed for passing.

Race organizers typically build the largest grandstands along this straight because spectators get the best view of race starts, finishes, and pit stop action. Famous examples include the long straight at Baku City Circuit in Formula 1, which sits below sea level, and the narrow Start/Finish Straight at Monaco's street circuit.
