What Happens To a NASCAR Race If It Rains?

From the rumble of the engines to the cheers of the crowd, NASCAR races are a sensory feast, a spectacle of speed and skill. But as in any outdoor sport, weather can throw a curveball. One condition particularly poses a unique challenge – rain. As NASCAR fans know, rain can alter race strategies, schedules, and outcomes.

When rain impacts a NASCAR race, traditionally the race may be delayed or even rescheduled. However, NASCAR has been evolving its approach, testing rain tires on shorter oval tracks and developing cars better suited to wet conditions. This could lead to fewer rain-induced interruptions in the future.

This article will navigate you through the stormy (ha!) world of rain-affected NASCAR races, helping you understand the policy, procedure, and implications when the skies open up on the race day.

Weather Conditions and Motorsports

Weather plays a critical role in any outdoor sport, and motorsports are no different. The elements can make the difference between a thrilling spectacle and a perilous event. Rain, specifically, has the power to transform a race completely, making surfaces slippery, reducing visibility and altering the handling of the vehicles.

But not all motorsports approach rain the same way. In some disciplines, like Formula 1, racing in wet conditions is part of the game, adding an extra layer of strategy and driver skill. Rain tires are fitted, drivers adjust their tactics, and the race goes on, well mostly

NASCAR’s Approach to Rain

However, NASCAR’s historical approach to rain has been markedly different. Dating back to its roots, NASCAR has been a fair-weather sport, primarily because of the nature of its tracks. NASCAR races on ovals with banked turns which, when wet, can become treacherously slick.

Additionally, the high-speed nature of the races poses a significant risk during wet conditions. So, for a long time, the standard protocol was simple: if it rains, the race is either delayed until conditions improve, or, if necessary, it’s rescheduled for another day.

This policy, born out of safety considerations, has its own complexities and implications, which we will explore further in this article.

What Happens When It Rains Before a NASCAR Race

When ominous clouds gather on race day, NASCAR and the racetrack officials spring into action. The first priority is to communicate any changes or potential changes to the race teams, officials, and fans. This could mean an altered start time, or even postponement to another day or in some cases daysOpens in a new tab.!

In parallel, race teams make their own preparations, adjusting their strategies, and if possible, their car setups, based on the weather forecast.

But the race isn’t called off at the first drop of rain – modern tracks often have advanced drying technologies, designed to get the race back on track as soon as possible.

The Role of Rain Tires in NASCAR

For many years, the mention of rain tires was a novelty in the world of NASCAR. They were a solution meant for road courses, where their treaded design could handle the wet pavement. On oval tracks, however, the high speeds and banking angles made using rain tires impractical.

But, as technology has evolved, so too has NASCAR’s approach to rain. In recent years, NASCAR has tested rain tires on shorter oval tracks, showing a willingness to adapt and evolve. It’s a complex issue, balancing safety, competition, and fan experience, but it’s a step towards making NASCAR a less weather-dependent sport.

What Happens When It Rains During a NASCAR Race

When rain begins to fall during a NASCAR race, it’s time for quick decisions. NASCAR officials closely monitor the weather and track conditions, and if necessary, may throw a caution flag and halt the race. This rain delay could last a few minutes or several hours, depending on the severity of the weather.

Races may even be shortened if conditions don’t improve, with the leader at the time of stoppage declared the winner.

During these weather interruptions, race strategy can turn on a dime, making it both a challenge and an opportunity for drivers and teams.

The Aftermath of a Rain-affected NASCAR Race

Once the skies clear, the focus turns to resuming or rescheduling the race. If a race has been merely paused, NASCAR and track officials work swiftly to dry the track using state-of-the-art equipment. The drivers then restart their engines and the race continues.

But if a race has been postponed, the logistics become more complex, requiring the rescheduling of the event, often to the next available day.

These rain-affected races can create ripples throughout the NASCAR season, shaking up point standings and testing the resilience of teams, drivers, and fans alike.

The Process of Drying a Wet NASCAR Track

When rain showers pass, leaving a wet track in their wake, NASCAR employs an impressive, coordinated effort to dry the track and get the race back on schedule. The star player in this effort is the Air Titan, a track drying system introduced in 2013.

The Air Titan uses compressed air to push water off the racing surface, which is then vacuumed away by a following fleet of vacuum trucks.

Alongside the Air Titan, NASCAR uses jet dryers – vehicles equipped with jet engines that blow hot air onto the track surface to evaporate the water. For areas that are hard to reach with these larger machines, smaller, more maneuverable drying equipment is used.

The whole process is a marvel of logistics, requiring coordination between numerous vehicles and officials to ensure the track is dried as quickly and safely as possible.

Depending on the severity of the rain and the length of the track, the drying process can take anywhere from 30 minutes to two hours.

Case Studies

A memorable instance of a rain-impacted NASCAR race occurred during the 2020 Charlotte Roval race. The race saw the drivers switch to rain tires and compete in wet conditions for the first time in a points-paying Cup Series event on a road course.

This added an exciting twist, as drivers had to adjust their racing styles to handle the slippery track.

Another historic example is the 2001 Pepsi 400 at MichiganOpens in a new tab.. Rain forced the race to be called off after 162 of the scheduled 200 laps, handing the victory to Dodge driving Sterling Marlin.

This race was a demonstration of the strategic implications of rain, as Marlin’s team had elected to keep their car on the trackOpens in a new tab. while others pitted, guessing that the rain might end the race early.

IX. Future of Rain-affected NASCAR Races

NASCAR’s handling of rain has evolved significantly over the years. The use of rain tires on a road course in 2020 was a milestone, and there is an ongoing discussion about expanding their use to short oval tracks as well, following positive testing at Martinsville Speedway in 2020 and a COTA race, (see video below) despite visibility issues helped cement their presence.

NASCAR’s introduction of the Next Gen car in 2022, designed with improved performance in wet conditions, shows the organization’s proactive approach to weather-related challenges.

While safety remains paramount, these advancements could potentially lead to more NASCAR races being run in the rainOpens in a new tab., reducing delays and rescheduling, and adding a new dimension to the racing action.

Rainy Day Tips for NASCAR Fans

Rain can bring a NASCAR race to a sudden halt, but that doesn’t mean the fun has to stop. Here are some tips for fans to navigate a rainy race day:

  1. Pack Wisely: Always check the weather forecast before heading to the track and prepare for the possibility of rain. Pack a waterproof poncho or raincoat, umbrella, and water-resistant footwear. Keep electronics and valuables in waterproof bags or containers.
  2. Shelter Options: Some NASCAR tracks have covered areas where fans can take shelter during a rain delay. However, these can get crowded quickly, so consider other options like retreating to your car if it’s nearby or bringing a small waterproof tent or canopy.
  3. Entertainment: Rain delays can last a while, so bring along items to pass the time such as books, portable games, or music.

Remember, safety should be your first priority, so follow the instructions given by track officials and staff during a rain delay. We also have some of the best ponchos both lightweight and cheap for those unexpected rain delays!


Rain and NASCAR have always had a complex relationship of delay, strategy, and evolution. The traditional approach – delay and reschedule – has given way to an embrace of rain tires and the exploration of new car technologies.

These changes could lead to exciting possibilities for the sport, opening up new strategies and tests of driver skill.

The relationship between NASCAR and rain continues to evolve, promising a future where we might not have to wonder what happens when it rains during a NASCAR race – instead, we’ll just sit back and enjoy the spectacle.
