A TOTAL of 544 people were killed or injured on Calderdale's roads in the first six months of this year, according to new figures.
Five people died, one more than for the whole of 2003.
With two months of the year still to go, council road safety officer Peter Shepherdson warned the district's road deaths could reach a 10-year high.
"Traditionally the last two months of the year are the worst for crashes because of the onset of dark nights, poor weather, poor visibility and everyone rushing round in preparation for Christmas, he said.
A total of 104 children were hurt on the roads in the first half of the years.
Mr Shepherdson said many were injured because they were not wearing seat belts.
"The number of people not wearing their seatbelts in Calderdale is reckoned to be over twice the national average," he said.
