What is the blood alcohol content limit for a graduated licence holder while driving?

The blood alcohol content limit for a graduated licence holder is set to promote safety and reduce the risk of impaired driving as they are still in the learning phase of their driving journey. The correct limit of 0% indicates that graduated licence holders are not permitted to have any detectable alcohol in their system while driving. This rule is in place to help ensure that these novice drivers can develop their skills and experience on the road without the impairment associated with alcohol consumption, which can significantly affect reaction times and decision-making.

The other options, which suggest a small allowable limit of alcohol, do not apply to graduated licence holders specifically, as the objective is to ensure complete sobriety while they are gaining experience behind the wheel.
