Police say 39-year-old Frederick Poust III hadn't slept for 24 hours when he rolled through 10 stops signs and plowed into a car near school, killing the car's passenger.
The Schwenksville man, while using a cellphone, also caused a 1999 crash that killed a toddler and fueled debate on driving with cellphones.
Poust apologized Thursday as he was sentenced for vehicular homicide in last year's death of 27-year-old Richard Taylor of Gilbertsville.
Defense lawyer Brian McMonagle says the oncoming car had no lights on and was hard to see on the gray winter morning.
