A lower alcohol limit is applied to novice drivers than to other drivers because, lacking sufficient driving experience, alcohol affects their driving more.
The maximum limit allowed for novice drivers (first 2 years of licence holding) and professional drivers will be 0.15 milligrams per litre of exhaled air and 0.30 grams per litre in blood.
For other drivers, including cyclists, it is 0.25 milligrams per litre of exhaled air and 0.50 grams per litre in blood.
The only safe level at the wheel is 0.0.
The V-13 sign, for novice drivers, which must be displayed on our vehicle, will be for 1 year and not for 2 years as is the case with the alcohol limit.
