Former President Bill Clinton's motorcade was struck by a car on his way to deliver a Class Day speech at Yale on Sunday.
The minor crash happened on the Merritt Parkway near exit 38, according to state police.
A car struck the Secret Service truck Clinton was riding in when it slowed in traffic but Clinton was not injured.
Clinton did not mention the crash during his speech.
He told Yale seniors to listen to people with whom they disagree.
His speech included points similar to a commencement address he gave a week ago in West Virginia, the Yale Law School alum said today's college graduates will be left to deal with a world that has three major problems.
"It is too unstable; it is too unequal, and it is completely unsustainable," Clinton said.
He urged them to change that, and said that will mean working together.
"One problem we have in the modern world is, we've got access to more information than ever before, but we don't all listen to the same information," he said.
During his speech, Clinton told Yale seniors that while the country is less sexist, racist and homophobic than it once was, people today only want to be around those who agree with them.
"In our media habits, we go to the television sites, we go to the radio talk shows, we go to the blog sites that agree with us, and it can have very bizarre consequences" he said, citing the controversy over the origin of President Obama's birth certificate.
He also warned that as information becomes more available, so does the potential for its misuse.
He noted that Faisal Shahzad, the man accused of attempting to bomb Times Square, received a college degree in the United States before flying back to Pakistan to train as a terrorist. *Shahzad attended the University of Bridgeport.)
"It shows you that when you tear down all the walls, and you can break through all the barriers of information, that the same things that empower you to get access to more information more quickly than ever before could empower you to build bombs," he said. "It's an unstable world."
Clinton said he believes the mission of every empowered person in the world should be to increase the positive forces and decrease the negative forces of the world's interdependence.
"We have to be relentlessly committed to change," he said. "And change is hard."
The address continued a Yale tradition in which graduation speakers typically don't speak at commencements. The major speech to seniors is instead given the previous day during Class Day festivities, an event that also includes the wearing of silly hats.
The former president said he considered turning a handkerchief he had been given by the class of 2010 into a do-rag so that he would better fit in.
"I wasn't sure I was coming to fashion week," he joked.
Clinton's wife, Secretary of State Hillary Rodham Clinton was Class Day speaker in 2001, and received an honorary degree last year.
