I was driving on the Pennsylvania Turnpike in the left-hand lane alongside the concrete barrier. The road curved to the right and when I tried to gently steer to the right the steering wheel got stuck and locked. I wasnât able to steer to the right and so the car hit the barrier. The steering then unlocked. Since I was trying to originally steer to the right, the car moved to the right and hit the guard rail along the right-hand side of the highway where the car finally came to a stop. It was fortunate that there were no other cars close to my car when this happened. I donât know what caused the steering wheel to lock up. The car was very badly damaged and eventually determined to be a total loss. I suffered a concussion and need ongoing PT and OT. Also, I am limited to only working part-time until my concussion symptoms improve. The car was well maintained and had passed the state inspections a couple of weeks before. The issue could have been caused by a front suspension assembly error.
