Bump and Run Meaning in NASCAR

A bump and run is a passing move involving a light rear-end collision. The trailing driver taps the back of the lead car to upset its balance. This contact moves the lead car up the track and opens a lane. The second driver then accelerates through the newly created gap to take the lead. A challenger used a bump and run on the final lap to win. This move works best in slow corners where the impact has lower physical risk. Professional racers consider this a legitimate but aggressive way to gain a better position. Executing this perfectly requires hitting the bumper without causing a major multi-car crash.
