Can You Bump In NASCAR?

Bumping, a tactic used by NASCAR drivers to assert their dominance on the racetrack, has long been a subject of debate among fans, drivers, and racing experts alike.

Quick Answer:

No, bumping is not allowed in NASCAR. It is considered aggressive driving and can result in penalties or disqualification. NASCAR emphasizes fair competition and discourages intentional contact between cars. Drivers are expected to maintain control and avoid unnecessary collisions while racing.

For those unfamiliar with the practice, bumping in NASCAR entails one driver lightly tapping the rear bumper of the car in front of them.

This action can serve various purposes, such as conveying a message to the driver ahead or initiating a risky passing maneuver.

Bump and Run Technique

The Bump and Run Technique is a widely used tactic in NASCAR and involves using the bumper of a vehicle to gain a positional advantage over a competitor.

This technique relies on precise timing and good judgment by the trailing car to execute it effectively.


Drafting plays a crucial role in the Bump and Run Technique. It involves positioning the trailing car close behind a leading car to take advantage of the reduced air pressure and resistance created by the lead car’s movement.

The trailing car can then use the draft to increase its speed while conserving fuel.

Bump Drafting: A specific type of drafting, called bump drafting, occurs when the trailing car makes contact with the back bumper of the lead car to gently push them forward. This helps both cars gain speed and maintain momentum. However, bump drafting requires considerable skill, as too much force can lead to crashes or spin-outs.

Famous Bump and Run Instances

Joey Logano

Joey Logano has executed the bump-and-run tactic several times throughout his career. One memorable instance occurred in 2018 at Martinsville Speedway, where Logano got a late-race bump to push Martin Truex Jr. out of the way, securing his first win at the track.

In another instance, Logano went head-to-head with Kevin Harvick in 2010 at Pocono, using the bump-and-run to take the lead and earn his victory.

Jeff Gordon

Jeff Gordon, a four-time NASCAR champion, used the bump-and-run to his advantage during his illustrious career.

At Bristol in 2002, Gordon employed this tactic during the final laps to pass Rusty Wallace and secure the victory. Gordon repeated the bump-and-run at the same track in 2005, this time against Matt Kenseth.

Dale Earnhardt

Known as “The Intimidator,” Dale Earnhardt was famous for his aggressive driving style, often using the bump-and-run throughout his career.

In the 1993 race at Bristol, Earnhardt bumped Terry Labonte on the final lap, flying by and earning a staggering win. Earnhardt also showcased his bump-and-run expertise at Talladega and Daytona, making it a signature move in his legendary racing career.

Mark Martin

Veteran racer Mark Martin has had his share of bump-and-run encounters during his NASCAR career. One notable example occurred at the 2009 race at Michigan, where Martin and Jimmie Johnson traded bumps during the final laps.

In the end, Martin used the tactic to take the lead and win the race. Another bump-and-run incident involving Martin happened at Richmond in 2008, where he and Carl Edwards exchanged positions before Martin ultimately emerged victorious.

Risks and Dangers

Race Car Crash

Spinning out

One of the most dangerous aspects of bumping in NASCAR is the risk of spinning out. When a driver makes contact with another car, it can cause the affected vehicle to lose control, potentially resulting in a spin.

This often occurs at high speeds, increasing the likelihood of a collision with the wall or other vehicles on the track. Drivers must maintain caution when attempting a bump-and-run, as their actions can lead to wrecks and ultimately lost laps for both themselves and their competitors.

Bumping can be especially risky during the final laps of a race, as tensions are high and drivers are focused on securing a win.

In some cases, drivers may even use their front bumper to push an opponent’s rear bumper in an attempt to gain an advantage, which can lead to dangerous spins and accidents.

High-Speed Bumping

High-speed bumping presents additional risks, as the forces involved are much greater and the margin for error is smaller. In these situations, even a slight misjudgment can lead to catastrophic outcomes.

When attempting a bump at high speeds, it’s crucial that drivers consider the following:

  • Caution: Drivers should be aware of their surroundings and the potential risks before deciding to initiate a bump. Bumping in high-speed circumstances can result in severe consequences, including crashes, injuries, and damage to both vehicles.
  • Revenge: In some cases, drivers may become frustrated or angered by intentional or unintentional bumps, leading to an escalation in aggressive driving tactics as they seek retaliation. This can increase the risk of accidents and put all competitors on the track in danger.
  • Proper technique: It’s essential to know the appropriate techniques when delivering a bump at high speeds. Connecting with another vehicle’s rear bumper in the correct way can help to minimize the risk of spinning out, although this should still be approached with caution.

NASCAR Rules and Penalties

Ban on Bump and Run

In NASCAR racing, bump and run is a controversial driving tactic where a driver intentionally makes contact with the rear bumper of the car in front, causing it to lose control and allowing the offending driver to pass.

This maneuver is considered dangerous and aggressive, and NASCAR has implemented rules and penalties to discourage its use.

Drivers who engage in the bump and run tactic can face significant penalties, including fines, loss of points, and even suspension from future races. These penalties are determined on a case-by-case basis, but consistency remains vital in ensuring all drivers are treated fairly.

Unwritten Rules

While NASCAR has formal rules and penalties in place to address the ban on bump and run, there are also unwritten rules among drivers.

These “gentlemen’s agreements” aim to promote fair and safe racing, as well as uphold the integrity of the sport.

Some of the unwritten rules include:

  • Giving space during restarts to ensure smoother and safer racing.
  • Not blocking aggressively, as this can lead to accidents and hard feelings among competitors.
  • Respecting other drivers, especially during the closing laps of a race.

The Daytona 500, one of NASCAR’s most prestigious events, is often a prime example of drivers adhering to both the formal NASCAR rules and the unwritten guidelines shared by racers.

With the high stakes of this race, drivers understand the importance of respecting their competitors and upholding the spirit of fair play.

Comparison with Other Racing Forms

Formula 1

In Formula 1, a form of open-wheel racing, contact between drivers is highly discouraged due to the fragile nature of the cars and the potential for high-speed accidents.

Hitting another car, even with a seemingly minor “bump and run” maneuver, can result in severe damage to both vehicles, unlike stock car racing, where drivers can use these tactics to gain a competitive advantage.

Formula 1 cars are built to grip the corners at incredibly high speeds, minimizing the need for drivers to rely on bumping techniques to advance their position. While both forms of racing involve navigating through tight corners, Formula 1 drivers must rely on finesse, strategy, and raw speed to compete successfully.

Touring Car Racing

Touring Car Racing, another form of closed-wheel racing, sees slightly more contact between drivers compared to Formula 1. However, it still maintains strict rules against excessive contact and intentional hitting.

As with NASCAR, Touring Car Racing involves racing on a mix of circuits with various corner types and lengths, which could lead to some bumping incidents. However, any significant contact can still result in penalties, as the primary focus is on fair competition and car control.

In contrast, NASCAR often tolerates the “bump and run” approach, with drivers like Kenseth executing such moves without significant penalties.

Bumping on Different Tracks

Martinsville Speedway

Martinsville Speedway, known for its tight corners and short track, is a challenging place for bumping in stock car racing. Bumping can sometimes be seen as a controversial tactic or even an art form.

Here, drivers must carefully nudge the rear wheels of the car ahead to maintain momentum and grip. This aggressive move can result in lead cars being overtaken, as seen in the infamous race between Jimmy Spencer and Ricky Rudd back in 1996.

Talladega Superspeedway

Talladega Superspeedway, on the other hand, is typically not associated with bumping since it is a larger track with high speeds. However, the track has had incidents where contact between cars has led to severe consequences.

In these cases, a bump could potentially send a car into the catchfence, causing a potential for injuries or damage to the vehicles. Consequently, drivers must exercise caution in such circumstances.

Pocono Raceway

Pocono Raceway presents unique challenges when it comes to bumping due to its distinct triangular shape. Each of its three turns has varying degrees of banking and wide straightaways, which can make bumping risky.

Drivers familiar with this track know when and where to apply bump-drafting, focusing on strategic locations that allow for easier passing or overtaking.

New Hampshire Motor Speedway

New Hampshire Motor Speedway (NHMS) is a flat mile-long oval track famous for its tight racing style and lack of aerodynamic grip. Bumping is often employed here, much like at Martinsville Speedway.

However, in NHMS, drivers must exercise extreme caution when bumping, as the close racing distances can escalate tensions among competitors and cause retaliation. Touring car racing often encounters these close-quarters and aggressive driving tactics, making bumping even more necessary for gaining position on this challenging track.

Race Strategies and Team Dynamics

In NASCAR, race strategies and team dynamics play a crucial role in determining the success of drivers on the racetrack.

Teammate Bumping

Bumping is a technique used in NASCAR where a driver intentionally makes contact with the rear bumper of the car in front to help them gain traction and increase their speed.

Teammate bumping is when two drivers from the same team work together by bumping each other to improve their positions in the race. This cooperation is often seen at high-speed racetracks like the Daytona International Speedway, where drafting (following closely behind another car to reduce air resistance) is an essential strategy.

Fans of the sport have mixed opinions on this practice. Some view it as an exciting and integral part of NASCAR racing, while others consider it a controversial tactic that can lead to dangerous accidents.

Here are some key factors that influence the effectiveness of teammate bumping:

  • Racetrack: Bumping is more effective on specific tracks, such as short tracks and high-speed superspeedways like Daytona.
  • Car manufacturer: Some manufacturers, like Ford, Chevrolet, and Toyota, develop cars that are better suited for bump-drafting.
  • Driver skill: The technique requires precise timing and control, so experienced drivers are often more successful at this strategy.

Backup Cars

In NASCAR, teams bring backup cars to the racetrack in case the primary car is damaged before or during the race. This allows a driver to continue competing even if their primary car faces a setback, enhancing their chances of success.

Backup cars are usually identical to the primary car in terms of setup and performance, minimizing the potential impact on the driver’s performance.

Teams invest considerable time and resources into preparing this second vehicle to meet the specific requirements of each race.

Let’s take a look at some circumstances where a backup car might be necessary:

  • Accidents: If a driver is involved in a crash during practice or qualifying laps that causes irreparable damage to the primary car, the backup car is brought in for the race.
  • Technical issues: If a primary car develops unexpected mechanical problems, the team might opt to use the backup car to avoid risking poor performance or further issues during the race.
  • Safety precautions: Teams may occasionally switch to a backup car due to concerns about the primary car’s safety or reliability after reviewing test data or inspecting the vehicle.

NASCAR Series and Bumping

Cup Series

In the Cup Series, bumping is a common but controversial practice. Drivers like Clint Bowyer have been known to utilize the bump-and-run technique to gain positions during races.

This involves making contact with the rear bumper of the car in front and pushing them slightly off their racing line, allowing the aggressor to slip by. However, NASCAR officials and fans often debate whether such moves are fair game or overly aggressive.

Xfinity Series

The Xfinity Series also sees its fair share of bumping incidents. Similar to the Cup Series, drivers may use the bump-and-run to advance their positions. NASCAR closely monitors these actions and may penalize drivers for excessive contact that leads to accidents or appears intentional.

As in the Cup Series, opinions on bumping vary among drivers, teams, and fans.

Camping World Truck Series

In the Camping World Truck Series, bumping can be even more prevalent due to the unique nature of truck racing. The larger, heavier vehicles may lead drivers to use bump-and-run tactics more frequently.

Again, NASCAR officials keep an eye on bumping incidents and may hand down penalties if they deem actions too aggressive or dangerous. The debate surrounding the legitimacy of bumping continues across all three series.

Throughout all NASCAR series, bumping is a common tactic, though opinions on its appropriateness vary. Individual drivers, teams, and fans alike all have their own perspectives on the matter.

The key takeaway is that while bumping may be a part of NASCAR, the sport’s governing body closely monitors for excessive aggression or dangerous driving.
