GUILDERLAND — The single student on board a school bus that was in a collision at the intersection of Western and Venezio avenues on Friday at about 6:54 a.m. was unhurt, according to Curtis Cox, deputy chief of the Guilderland Police. Cox gave the student’s age as 19.

Cox said that the school bus — one of the Guilderland School District’s smaller buses — was heading east on Route 20, making a right turn onto Venezio Avenue.

He described events unfolding this way:

The vehicle directly behind the school bus slowed down to allow it to make the turn.

But another vehicle came from behind and moved from the left to the right lane. The driver of that vehicle admitted to being distracted, and to failing to see that the traffic in front of him had slowed down, Cox said.  He hit the vehicle in front of him, sending it into the back of the school bus.

The driver of the vehicle that was struck from behind and sandwiched in the middle was sent to the hospital for evaluation.
