AUGUSTA, Maine — Maine State Police say 100 people have been killed on Maine highways so far this year — the lowest total to this point in at least 16 years.

And as Labor Day weekend arrives, police aim to keep the number of fatalities down.

State police and 66 other Maine police departments will be using federal money for additional drunken driving patrols this weekend.

Last year, 114 highway deaths had been recorded in Maine through the Labor Day holiday weekend, and in 2007 the total was 108. By comparison, there were 141 road deaths in both 2003 and 2004 preceding Labor Day.
