The plane landed intact on Route 23 in West Milford. N.J., WABC reported.
Andrew May told WABC he was driving his truck down the highway when he saw the Cessna fixed-wing aircraft. He said the pilot guided the plane onto the highway to avoid traffic and then pulled to the side of the road.
"It almost felt like the plane hit us," he said. "That's how close it was. Thank God it didn't."
He added, "He did a really good job landing the plane, so kudos to him."
