A blitz on vehicles going in and out of the Christchurch central city red zone has been launched by police today.
Two heavy trailers with faulty brakes were ordered off the road and 12 commercial vehicles were fined for exceeding road user charges during the police operation this morning.
From around 6.30am, police at four separate checkpoints stopped several hundred vehicles, bikes and pedestrians entering the CBD red zone.
Senior Sergeant Mike Jones says police were conducting checks on vehicles and drivers for a range of issues including vehicle compliance and roadworthiness, driver's licenses, alcohol and drugs, as well as general checks on individuals coming into the red zone.
"Some of the results for commercial vehicles were disappointing," he says.
