An apparent road rage incident involving a man armed with a machete was caught on camera in North Salem Tuesday.

Cellphone video shows a man in a black jacket pulling out a footlong machete, and slamming it so hard onto a stopped truck that it breaks.

It happened in the middle of stopped traffic on I-68 around 8 a.m.

State police say the incident began when 46-year-old Roderick Davis of Danbury, chose to skip traffic by driving up the shoulder of the road.

That's when police say he cut off a truck driver, before getting out of his own vehicle and then getting his machete, all while his 15-year-old son looked on.

Fellow truck driver Kyle Gaedeke caught Davis's knife-wielding tantrum on video, stopping his recording only to get help from an off-duty officer who just happened to be stuck in the same traffic.

Police say they also found 30 grams of marijuana in Davis' car after dozens of officers were called to defuse the incident on the busy highway.

Police say Davis is now behind bars in Westchester County Jail, facing one felony, four misdemeanors and two violations. Those include criminal possession of a weapon, endangering a child and drug possession.
