Drivers caught with a blood alcohol content of .04 or higher with children in the vehicle will now face stiffer penalties.
The Traffic Safety Amendment Act, 2017 implements an immediate seven-day administrative driving suspension on a first offence for a person who transports a child under the age of 16 while impaired.
Repeat offenders who transport passengers under the age of 16 will face even more severe consequences.
Licence suspensions for a second offence increase to 30 days from 21, while a third offence triggers a 120 day suspension, up from the current 90.
New drivers already face licence suspensions of up to 18 months on a third offence.
