NEW YORK — Officials say a fatal accident this weekend involving a rented party bus carrying dozens of teenagers should be a warning to passengers of the dangers of opening emergency hatches.

A teen was killed when he poked his head through a hatch that had been opened on a double-decker bus.

Daniel Fernandez, 16, was fatally struck when the bus went under an overpass, authorities said.

Teenagers jubilantly sticking their heads through the roofs of stretch limousines is a familiar scene on city streets and in movies. A bigger version of that is the rented party bus, which can pack in more guests.

Party buses can be two stories high, offering such amenities as strobe lights and satellite TV. Renting such buses ‘‘is what kids call fun nowadays,’’ said Emily Darocha of the Silver Star Limousine company.

But such trips also carry more risk, Darocha said. ‘‘No matter how many times you tell clients this is an emergency exit — it’s written on the glass — they still open it,’’ she said. “It happens all the time.’’

In addition to the driver, a security guard was on board the bus Fernandez was riding that was taking the teens from New York City to a sweet 16 party in New Jersey. Design Limousines of New York, which operated the double-decker bus, did not return calls seeking comment on whether other chaperones were on board.
