Squad (4), Engine (3), and Traffic 33 responded to I81 NB MM56.6 for an accident with entrapment. Crews from the township companies arrived to find one vehicle on its side with the driver confined inside. The vehicle was properly stabilized and the roof was removed using hydraulic tools. The driver was found seat belted in the vehicle and was removed. The second vehicle involved also crossed from the SB to NB but no one was injured in that vehicle. Crews were out 45 mins. The section of 81 between Exit 52 and 57 is still without crossover protection and has a history of this type of accidents.
