All B-Line buses will trial Mobileye, a forward-facing collision avoidance technology system developed by Intel.
The Mobileye device will use audio and visual signals to alert a driver to potential collisions and provide lane departure warnings.
Mobileye was first trialled on a B-Line bus earlier in 2018 before being rolled out to all 38 B-Line buses.
Minister for Transport and Infrastructure Andrew Constance said the state-of-the-art safety feature could benefit all road users.
"Public transport safety is a top priority for the NSW Government, so investing in a trial of technology that could save lives and prevent injuries was an easy decision to make," Mr Constance said.
"Our B-Line drivers will now have a third eye on the road to help keep customers and other road users safe."
