Clearer field of view

Due to their shape and size, trucks have larger blind spots than other vehicles.

A Fresnel lens is a thin plastic lens attached to the passenger side window on a heavy vehicle. It provides the driver with a wide-angle view as they look through the lens. At a glance, the driver is able to see in their blind spot and notice other road users who may otherwise have been hidden.

Watch our video for more information on the Fresnal lens.


Fresnel lens trial

Transport for NSW trialled the effectiveness of the Fresnel lens in minimising passenger side blind spots on heavy vehicles and heavy vehicle driver attitudes towards using the lens.

The trial found that 61 per cent of the participants reported having the Fresnel lens made driving at least a bit safer, while 15 per cent indicated the Fresnel lens had helped them to avoid a potential crash one or more times during the evaluation.
