Young Drivers and Drinking and Driving: Zero Tolerance, Zero Risk
Share
For drivers in the probationary period, the rule is very strict: the maximum allowed level is 0.2 g of alcohol per liter of blood, or 0.10 mg per liter of breath. In practice, this corresponds to a logic of almost zero tolerance.
Just one drink can be enough to exceed this limit. For a young driver, the issue is simple: anticipate, do not drive after drinking, and use a reliable breathalyzer whenever there is the slightest doubt.
Alcohol and young license holders: what does the law say?
In France, since 2015, drivers in the probationary period must not drive with a blood alcohol level equal to or greater than 0.2 g/l of blood, or 0.10 mg/l of breath. This rule particularly concerns young drivers, novice drivers, and those who have recently obtained or recovered their license.
This threshold is much lower than that applicable to experienced drivers. It aims to reduce accident risks among less experienced drivers, as alcohol slows reflexes, impairs alertness, reduces the field of vision, and encourages risk-taking.
0.2 g/l of blood
This is the maximum threshold applicable to drivers with a probationary license. In practice, this means not consuming alcohol before driving.
0.10 mg/l of air
This is the equivalent measured during a test by a breathalyzer.
Zero alcohol
To avoid any risk, the safest solution remains not to drink before driving.
Remember: for a young license holder, “one drink” can already be too much. Metabolism, fatigue, sex, weight, food intake, and the time elapsed since consumption can affect the actual level.
What are the risks in case of a positive test?
In case of a positive alcohol test while driving with a probationary license, the consequences can be immediate. The driver risks a fine, point deduction, vehicle immobilization, and license suspension depending on the situation.
The real risk for a new driver: losing their license very quickly.
A probationary license starts with a limited number of points. An offense costing 6 points can therefore have much more serious consequences than for an experienced driver.
How to respect zero alcohol tolerance when driving?
The safest method is simple: do not drink alcohol before driving. Tricks like drinking water, eating, having coffee, sleeping a few minutes, or waiting “a bit” do not eliminate alcohol quickly.
Designate a sober driver
Before the evening, decide who will drive. The rule “Sam, the driver is the one who doesn’t drink” remains the best protection.
Plan an alternative
Public transport, taxi, VTC, carpooling, on-site accommodation, or delayed return: the solution must be planned before drinking.
Test yourself if in doubt
A breathalyzer allows you to check your blood alcohol level before making a decision. If in doubt, do not drive.
Do not trust your feelings
Feeling “fine” does not mean being below the legal limit. Alcohol can impair reflexes even when you think you are in control.

Why use a breathalyzer when you are a young driver?
A breathalyzer should not be seen as permission to drink and then drive. It should be understood as a prevention tool, useful to avoid risk-taking when you do not know your exact blood alcohol level.
Simple, compact, and practical
The chemical breathalyzer is a one-time solution, easy to carry, suitable for parties, events, vehicles, prevention kits, or public distribution.
Reusable and accurate depending on the model
The electronic breathalyzer allows multiple tests and is suitable for individuals, associations, businesses, events, or organizations wishing to strengthen their prevention efforts.
Important: a breathalyzer must be used according to its instructions. You must respect the waiting time after the last drink, avoid any immediate measurement after drinking, and never drive if in doubt.

Frequently asked questions about alcohol and young licenses
What is the allowed alcohol level for a young license holder?
The maximum allowed level is 0.2 g/l of blood, or 0.10 mg/l of exhaled air. In practice, this corresponds to an almost zero tolerance rule.
Can a single drink be enough to exceed the limit?
Yes. For a driver with a probationary license, a single drink can be enough to reach or exceed the legal limit depending on context, metabolism, fatigue, weight, sex, and time since consumption.
What is the penalty for alcohol while driving with a probationary license?
The driver risks a fine, a 6-point deduction, license suspension, and vehicle immobilization depending on the situation.
Is a breathalyzer mandatory in the car?
No, it is not mandatory to have a breathalyzer in your car. However, it remains very useful as a prevention tool, especially for young drivers.
How long should you wait before driving again?
There is no reliable universal waiting time. Alcohol elimination depends on many factors. In case of consumption or doubt, the only safe decision is not to drive.
Conclusion: young license, alcohol, and driving should not mix
For young drivers, the legal limit is very low: 0.2 g/l of blood. This rule requires maximum vigilance, as a single drink can already create a legal risk and especially an accident risk.
The best strategy remains not to drink before driving, to plan a way home, and to keep a breathalyzer available to avoid dangerous decisions.
