100 speed limit
A 100 km/h Speed Limit for Petrol Cars and Trucks Across Europe
A Simple Reform for Safety, Energy Independence and Climate Responsibility
By Gunther Fehlinger, Vienna
Europe faces three simultaneous challenges: energy dependence, climate responsibility and road safety. While politicians debate complex regulations, one of the simplest and most effective reforms remains largely ignored: a European-wide speed limit of 100 km/h for all petrol-powered cars and trucks.
This measure would immediately reduce oil consumption, cut emissions, improve road safety and strengthen Europe’s strategic autonomy.
Europe Must Reduce Oil Dependency
Petrol is overwhelmingly imported. Every unnecessary litre burned on European highways means more money flowing to unstable regions and authoritarian regimes.
At 160 or 180 km/h a petrol vehicle consumes dramatically more fuel than at 100 km/h. Aerodynamic drag increases exponentially with speed, meaning fuel consumption skyrockets beyond 120 km/h.
A 100 km/h limit would reduce petrol consumption by 20–30% on highways, saving billions of euros and reducing Europe's vulnerability to energy shocks.
Europe should not finance regimes hostile to European values simply because drivers want to go faster.
Climate Policy Without Bureaucracy
European climate policy is often criticised for being complicated and expensive. A 100 km/h petrol speed limit is the opposite: simple, cheap and effective.
Lower speeds mean:
Less CO₂ emissions
Less air pollution
Less noise pollution
Less tyre and brake dust
Unlike subsidies or complex regulations, this policy works immediately and costs taxpayers nothing.
Road Safety First
Speed is the single most important factor in road fatalities. The faster a vehicle travels, the higher the kinetic energy involved in accidents.
A universal 100 km/h highway limit for petrol vehicles would significantly reduce fatal accidents across Europe.
Countries that reduced highway speeds have consistently seen major improvements in road safety.
Europe should prioritize saving lives over the illusion of unlimited speed.
A Fair Policy for the Electric Transition
Electric vehicles should not be penalized for the inefficiencies of petrol technology. Petrol cars are the main source of oil dependence and emissions.
Therefore the rule should apply specifically to petrol-powered vehicles and trucks.
This creates a clear incentive for electrification without banning petrol cars outright.
Drivers remain free to choose their vehicle—but they must accept the energy reality of combustion engines.
European Unity on the Roads
Currently speed limits vary widely across Europe. Some countries allow very high speeds, while others already enforce limits around 100–120 km/h.
A European standard of 100 km/h would bring clarity, simplicity and fairness across the Single Market.
Just as Europe unified many economic rules, it should also unify basic road safety standards.
The famous German Autobahn without speed limits is an outdated relic of the fossil fuel era.
Europe in the 21st century must be efficient, safe and energy-independent.
The Right Time for Reform
With geopolitical tensions, energy instability and the need for climate responsibility, Europe must adopt practical policies that deliver immediate results.
A 100 km/h speed limit for petrol vehicles across Europe is exactly such a reform.
It saves fuel.
It saves lives.
It reduces emissions.
And it strengthens European independence.
Europe should act now.
