Teenagers' licences suspended at Scheyville

Two teenage P-platers have had their licences suspended after being detected by police travelling at speeds of more than 140km/h at Scheyville.

Hawkesbury Traffic and Highway Patrol officers were conducting stationary speed enforcement in a 70km/h zone on Scheyville Road shortly after 10.30pm on Friday, January 24 when they detected two approaching vehicles on the lidar travelling at 154km/h and 145km/h.

"Both vehicles were stopped and the male drivers - an 18-year-old from Kellyville and a 17-year-old from Glossodia - produced P1 provisional licences," police said in a statement.

"They were issued traffic infringement notices for exceeding the speed limit by more than 45km/h and their licences were suspended for six months."

Traffic and Highway Patrol Commander, Assistant Commissioner Michael Corboy, said it was disappointing to see young people driving in this manner and reminded drivers to stick to the speed limit.

"Speed limits are there to keep drivers, passengers and pedestrians safe. Travelling at such high speeds is unacceptable at any time and it is lucky there wasn't a more devastating outcome," Assistant Commissioner Corboy said.

"Driving is a privilege and road users need to be respectful of their surroundings, we want to see everyone return home safely to their family and friends".

The incident occurred on day one of Operation Safe Return, which started on January 24 and concludes at 11.59pm tonight (Monday, January 27).

Double demerits will be in force throughout the period for speeding, seatbelt, mobile phone and motorcycle helmet offences.

NSW Police officers will also be targeting other poor driver behaviour, including drink-and-drug-driving.
