A collision between a pickup truck and a car sent one of the vehicles careening onto the front lawn of a house on Valley Forge Road in Lansdale Friday afternoon. The white Pontiac came to a stop after hitting the front steps of the structure. Its driver sustained a head injury and was taken to the University of Pennsylvania Hospital for treatment. One of the passengers in the car was also taken to a hospital for evaluation. Police say the car was westbound on Delaware Avenue and apparently ran the stop sign at Valley Forge Road. The investigation is continuing into the cause of the accident.
