Sydney’s tunnels are required to meet air quality standards set to protect public health.
However, NSW Health advises that closing your windows and switching your vehicle ventilation to re-circulate will further reduce your exposure to vehicle emissions. These benefits can be achieved whether or not your air conditioning system is in use.
People with asthma
Some people with asthma are particularly sensitive to air pollution. To reduce exposure to vehicle emissions in peak periods, close your windows and switch your vehicle ventilation to re-circulate.
If you would like more information on the effects of air pollution on asthma, contact NSW Health on 02 9816 0234 or the Asthma Foundation of NSW on 1800 645 130.
