Two people were taken to the hospital after a rollover crash in Rochester late Friday night.
Police were called to Route 490 East near Culver Road around 11:45 p.m.
State police say one vehicle was following a car too closely and forced that car out of the way. The vehicle then went into the median and flipped over.
The drivers of both cars were taken to Strong Hospital by ambulance with unknown injuries.
Police closed Route 490 East from Culver to Winton while they investigated.
Troopers believe alcohol played a role in the crash.
