Two drinks at the restaurant, a roadside check on the way back, a breathalyzer showing 0.52 g/l. The evening takes a turn. In just a few minutes, the driver loses 6 points, receives a fine of 135 euros, and potentially faces a summons to court. The reality of penalties for drunk driving far exceeds just a ticket. The overall cost of such an offense amounts to hundreds, sometimes thousands of euros, not to mention the consequences on professional life.
Penalties vary according to blood alcohol level
A driver caught with a blood alcohol level between 0.5 and 0.79 g/l commits a 4th class offense. The fixed fine reaches 135 euros, increased in case of late payment. The withdrawal of 6 points from the driving license is systematic. An administrative suspension may also apply. In this situation, consulting a drunk driving lawyer allows for evaluating options for contesting or reducing penalties. The Kirmen & Lefebvre firm particularly assists drivers facing these procedures by analyzing potential procedural defects during the check, a defense lever often overlooked.

Above 0.8 g/l, the offense shifts to the criminal realm. The driver faces fines of up to 9,000 euros and 3 years in prison under the law of July 9, 2025. The retention of the license now lasts 120 hours (compared to 72 hours previously), and a 6-month administrative suspension becomes mandatory. The vehicle may be immobilized or confiscated.
Young drivers on a probationary license face an even stricter regime. The legal threshold drops to 0.2 g/l of blood, which means zero drinks in practice. A single infraction is enough to trigger a withdrawal of 6 points, which can invalidate the license in the first year.

The awareness course, an often underestimated obligation
The road safety awareness course is included in almost all penalties related to drunk driving. Mandatory for probationary license holders upon losing 3 points or more, it can also be imposed by the court in case of a felony. Its duration covers two consecutive days in an accredited center. Its cost ranges between 170 and 280 euros, fully borne by the driver.
The course, however, allows for the recovery of 4 points, once per year at most. For drivers whose point balance reaches a critical threshold, this recovery sometimes represents the only alternative to license invalidation.
According to the official government website, the court may also impose the installation of a breathalyzer ignition interlock device (EAD) on the vehicle. The device prevents starting if the alcohol level exceeds the programmed threshold. Installation costs around 1,500 euros, to be borne by the offender.
The real cost far exceeds the fine
The ticket represents only the visible part. The true financial impact of a drunk driving offense includes the fine, the awareness course, attorney fees if the case goes to court, increased auto insurance premiums (the surcharge can reach 150% after a conviction), and any costs related to the EAD.
The loss of the license also leads to direct professional consequences. A salesperson, a delivery driver, or a tradesperson who can no longer drive for six months finds themselves in a deadlock. The economic damage then far exceeds the amount of the initial fine.
In case of reoffending within five years, license cancellation becomes automatic. The driver must then retake the theory test, the driving exam, and undergo a medical examination as well as a psychotechnical test before being able to drive again.
