There were no fatal accidents in the north-west region that includes Blacktown despite nine people being killed on NSW roads over the Labor Day long weekend.
Police said Operation Slow Down started at midnight last Friday and ended at 11.59pm on Monday, October 7.
A police spokeswoman said 18 people were injured in 69 motor accidents in the region that also covers the Hills district, Holroyd, Mt Druitt and Parramatta.
She said highway patrol officers conducted 24,374 breath tests and charged 44 drivers for drink driving, 685 drivers for speeding and 82 people for not using safety belts or child restrains in the region.
One of those caught speeding was a 23-year motorcyclist on a student visa.
Police said at 10.30pm on Sunday officers from Mt Druitt highway patrol detected a motorcycle travelling east on the Great Western Highway at Eastern Creek at a speed of 140km/h in an 80km/h zone.
Officers stopped the rider and issued him with an infringement notice for exceeding the speed limit by more than 45km/h, and suspended his visiting-driver licence for six months.
The motorcyclist was one of those 4924 who received speeding infringements in NSW.
Police took 180,717 breath tests and charged 269 drivers for drink-driving.
“Our goal in every operation is zero fatalities, so we are disappointed that nine people have lost their lives in traffic incidents since Friday,” NSW Police Traffic and Highway Patrol Commander, Assistant Commissioner John Hartley said.
He said the current NSW road toll for 2013 was 258, which was 28 less than the same time last year.
