The Olympic champion was involved in the collision in Los Angeles on Saturday, 7 February. While he was lucky to walk away unharmed, one driver lost her life and five other people were taken to hospital.
In a statement, the reality star has now said: "My heartfelt and deepest sympathies go out to the family and loved ones, and to all of those who were involved or injured in this terrible accident.
"It is a devastating tragedy, and I cannot pretend to imagine what this family is going through at this time. I am praying for them. I will continue to cooperate in every way possible."
Bruce, 65, voluntarily took a sobriety test at the scene (which he passed) before being questioned and sent home. Investigators have said many people were questioned in relation to the incident, not just Bruce.
It's thought the pile-up in Malibu began when one car was hit from behind by another car. Bruce's vehicle is said to have crashed into the back of the second car, sending it spinning into oncoming traffic.
Bruce's rep has denied suggestions the Keeping Up With The Kardashians star was texting at the time of incident, saying he will happily provide phone records to prove this isn't true.
The athlete became internationally famous during the 1976 Olympic Games when he took home gold in the men's decathlon. More recently, he's found a new fanbase thanks to his appearances in Keeping Up With The Kardashians.
He split from his wife of 22 years, Kris Jenner, in 2013. They have two children together: Kendall, 19, and Kylie, 17.
