A school bus taking children on a field trip to a New Jersey historic site collided with a dump truck Thursday, ripping the bus apart and killing a teacher and student.

The crash left the bus lying on its side on the guardrail of Interstate 80 in Mount Olive, its undercarriage and front end sheared off and its steering wheel exposed. Some of the victims crawled out of the emergency exit in the back of the bus and an escape hatch on the roof. More than 40 people were taken to area hospitals.

“I heard a scraping sound and we toppled over the highway,” said student Theo Ancevski, who was sitting in the fourth row of the bus and was treated at a hospital for cuts and scrapes. “A lot of people were screaming and hanging from their seatbelts.”

New Jersey Gov. Phil Murphy said that one adult and one student were killed. Murphy said the driver of the truck was alive at the hospital, but officials didn’t reveal his condition.

The front end of the red dump truck was mangled in the wreck, which took place about 50 miles (80 kilometers) west of New York. The truck was registered to Mendez Trucking, of Belleville, and had “In God We Trust” emblazoned on the back of it.

Police didn’t release details of how the crash happened, but the trucking company had a string of crashes in recent years and a higher than average rate of violations that sidelined its vehicles, according to federal safety data.

There were 45 people, including 38 students, on the bus. Forty-three people from the bus and the truck driver were taken to three area hospitals.

The bus was owned by the school district and equipped with seat belts, according to Paramus schools superintendent Michele Robinson.

The bus was taking students from East Brook Middle School to Waterloo Village, a historic site depicting a Lenape Indian community and once-thriving port about 5 miles from the crash scene.

Some of the children were still inside the bus and some were outside when first responders arrived, according to Jeff Paul, director of the Morris County Office of Emergency Management.

“We had patients laying all over the median and on the interstate,” Paul said. “There were all kinds of injuries, every injury type you could expect in a crash of his magnitude.”

Paul said some of the first responders were “very emotionally upset. It was a rough scene to see.”

Zainab Qureshi, 11, told The Record she was on one of the two buses not involved in the crash. She said those two buses made it to Waterloo Village, but they were told by teachers and chaperones about a half hour later that they had to return to school because of bad weather.

Students on two other buses on the field trip returned to the school about 50 miles (80 kilometers) from the crash site and were reunited with their parents. Qureshi said students on the other buses didn’t find out about the crash until they arrived back at school.

Thuy Nguyen, a nurse from Paramus, was leaving the school with her eighth-grade son who was back at the school taking a standardized test and not in the bus. She said she rushed to the school after hearing the news.

“My heart just dropped, You hear the name of the school…” she said before trailing off.

Mendez Trucking has about 40 drivers and trucks, according to the Federal Motor Carrier Safety Administration. A message left with the company wasn’t immediately returned. Its trucks have been in seven crashes in the last two years, none of them fatal, according to FMCSA.

Mendez was fined $22,850 in 2016 for violating regulations on inspections, repairs and maintenance and post-crash drug and alcohol testing, according to the FMCSA.

Mendez trucks have racked up more than 130 violations in the last two years, according to FMCSA, including 27 for excessive weight, 17 for leaking, spilling or falling cargo and four speeding violations — three of them this year.

Mendez has a higher than average vehicle out-of-service rate, which means inspections found violations which had to be corrected before the vehicle could be returned to service. Mendez’s rate was 37.9 percent, according to FMCSA. The national average is 20.7.

According to the National Highway Traffic Safety Administration, 118 people on school buses were killed in crashes from 2007-2016, the last year for which data is available.

Of those killed, 68 were passengers — including 58 school-age children — and 50 were drivers. School bus crashes killed 902 people in other vehicles over that span.
