Survey Exposes a Reckless Habit on French Motorways

A survey released by Ipsos BVA for the Vinci Autoroutes Foundation on 31 July paints a worrying picture of driver behaviour as France endures a severe wildfire season. According to the poll, 17% of smokers admit to throwing their cigarette butt out of their vehicle window while on the motorway — a habit that directly feeds the country's escalating fire risk.

The findings come as the Minister of the Interior, Laurent Nuñez, warned that fire danger remains “extremely high” despite some improvement in the Gironde region. More than 14,000 fires have been recorded since the start of the season, burning 117,000 hectares. The foundation's 12th annual summer study on waste management during holiday travel describes such behaviour as “alarming”.

While 87% of French people now recognise that throwing a butt from a vehicle poses a major fire risk, the gap between awareness and action remains stark. Smoking in a car is not banned unless a minor is on board or the act compromises safe driving, but since 2023 it has been illegal to smoke in woodland during high-risk periods. Throwing a butt that sparks a fire can lead to severe penalties, including up to 10 years in prison and a €150,000 fine when the fire results in death.

The survey, conducted online from 19 to 23 June among 2,279 people representative of the population aged 16–75, also found that one third of respondents have already been affected, directly or indirectly, by a forest fire, and 60% believe they are likely to feel the consequences in the coming years.

Why a Simple Act of Negligence Fuels a National Fire Crisis

The Persistent Gap Between Awareness and Action

Despite near-universal recognition of the danger — 87% view the act as a major fire trigger — the same proportion of smokers continues to discard butts on the road. Behavioural inertia suggests that awareness campaigns alone are insufficient to change deeply ingrained habits, especially during the relaxed atmosphere of holiday travel.

A Legal Framework Designed to Deter

French law has tightened since 2023: smoking in forests during fire-risk periods is prohibited, and the criminal penalties for starting an involuntary fire with a thrown butt can reach a decade in prison and a six-figure fine. Enforcement on motorways, however, remains challenging, relying chiefly on witness reports or visible flames rather than proactive policing of moving vehicles.

The Intersection of Human Behaviour and a Changing Climate

Official figures state that 90% of forest fires are human-caused, and more than half stem from negligence or dangerous acts. With hotter, drier summers intensifying fire risk, the consequences of such ordinary carelessness grow more severe. The shift in public sensitivity — 60% now fear personal impact — reflects a population coming to terms with an environment in which a single cigarette butt can devastate thousands of hectares.

What Every Driver and Smoker Should Know

  • Dispose of butts safely. Use the ashtray in your vehicle, never the window. On a rest stop, extinguish fully before binning.
  • Know the law. Since 2023, smoking in woodland during fire season is forbidden, and starting a fire with a negligently discarded butt can lead to a €150,000 fine and up to 10 years’ imprisonment if someone dies.
  • Be extra vigilant in high-risk periods. The current fire season has already seen 14,000 blazes, and dry ground makes any spark a potential catastrophe. If you see a fellow road user throw a butt, consider reporting the licence plate to the gendarmerie.
