Alabama Department of Public Safety officials say four people were killed in crashes during the Fourth of July travel period.
The holiday travel period began at 12:01 a.m. Thursday and ended at midnight on Sunday. State patrol officials say they investigated 434 traffic crashes, which resulted in 154 injuries.
The four traffic fatalities don't include traffic accidents that were investigated by other law enforcement agencies. Officials say they're unsure of whether alcohol was linked to any of the crashes and seatbelts were used in one of the four deadly accidents.
