Damage was observed on the front passenger door. No injuries reported. MV2 operator states she was driving on Washington St and approached the merge at the beginning of the bridge to change lanes and head onto the Mass Pike W-Bound, when MV1 collided with her vehicle. Damage was observed on the front drivers side bumper. MV2 operator reported having whiplash but signed a medical refusal and was not transported to the hospital. I then cleared without further incident. The main crash factor was due to the weather being a heavy rain storm at night. It should be noted there is a yield sign facing MV1s incoming direction.
