More than 600 drivers have been booked by the Land Transport Authority for the use of vehicles that are emitting excessive smoke.

Media officer Ratu Eroni Volavola said this comes as a result of their month long campaign aimed at reducing the number of vehicles that are emitting hazardous black smoke which is harmful to our health and environment.

Volavola said 450 drivers have been booked within the central/eastern division, while as of Tuesday 180 were booked from the western division.

He added drivers were charged with a $100 spot fine and told to pay within 21 days or face court action.

Volavola added they are also happy with drivers change of attitude to ensure children under the age of 8 are properly secured whilst travelling in vehicles.

He said they have noted although most do not have the proper child safety seat, drivers have taken their advice to ensure children are safely seated at the back with an adult.

The month long campaign ends tomorrow.
