France has extended alcohol and drug checks to coastal waters after an amendment to the Ripost law was adopted in July.
The change follows the death of an eight-year-old child in the Arcachon basin in May 2025, which exposed a legal gap: maritime waters were not covered by the sobriety rules that already apply to inland waterways such as rivers and lakes.
On inland waterways, the rules mirror road traffic law: blood alcohol must stay below 0.5 grams per litre, with zero tolerance for drugs. A positive test can lead to licence suspension and a fine of up to 750 euros.
The Ripost amendment also strengthens criminal penalties for professionals and recreational boaters alike. Drunk boating can now carry up to three years in prison and a 9,000-euro fine, with aggravating circumstances when alcohol and drugs are combined. Implementation decrees are expected to make the measure effective in 2027.
A fishing guide on the Loire, who tested negative during a routine check, said the increased patrols were welcome because the area sees growing numbers of tourists and boaters who sometimes disregard the rules.
In 2025, 33 people died in recreational boating accidents at sea.
