Highway patrol police in Newcastle pulled over a Nissan Qashqai on April 10 after it caught their attention.

NSW officers stopped the vehicle at about 3.15pm after detecting an alleged traffic offence.

The 37-year-old woman behind the wheel allegedly blew a positive roadside breath test and was taken to Waratah Police Station.

Police allege she recorded a high-range blood alcohol reading of 0.158, more than three times the legal limit for a fully-licensed driver.

She was issued a notice to front Newcastle Local Court at a later date and her license was suspended on the spot.

Police allege the woman had an eight-year-old child in the SUV at the time, and it's understood she may have earlier picked them up from school.

The woman was also hit with a number of other traffic infringements, including for driving an unregistered car.
