Swiss speed limit proposal sparks debate

A proposal to lower the speed limit on Swiss highways from 120 km/h to 80 km/h has reignited discussions about energy policy and transportation strategies, with reactions ranging from skepticism to concern over the implications for electric vehicles. The idea has drawn criticism, particularly in France, where it is viewed as unpopular.

Historical context of speed limits

Swiss motorists have noted that the country's main routes rarely allow speeds higher than 120 km/h, a point that echoes historical measures taken during the 1970s oil crisis. In 1973, the Swiss government reduced the speed limit on highways to 100 km/h to conserve fuel, a policy that was later adjusted in 1985 to 120 km/h, initially as a temporary measure to address forest degradation but eventually becoming permanent in 1989.

Fuel shortage concerns and policy focus

According to the Federal Office for Economic Supply (OFAE), cited by 20minutes on October 24, 2026, a potential scenario of serious fuel shortages in Europe could lead to measures such as mandatory fuel reserves, promotion of public transport, and a general reduction in highway speed limits to 80 km/h. The OFAE's reasoning focuses on internal combustion engines, seemingly disregarding the progress of the energy transition.

Impact on electric vehicles

This approach has raised concerns, as it would apply uniformly to all vehicle types, including electric vehicles, which do not consume fossil fuels. From a physical standpoint, reducing the speed limit from 120 km/h to 80 km/h could decrease fuel consumption by 20 to 30%, potentially easing tensions on fuel supplies during a crisis.

Criticism of policy and electric vehicle support

However, this measure is seen by some as an anachronism, bringing back policies from the 1970s. Additionally, the proposal does not differentiate between vehicle types, which could be problematic for electric vehicle drivers, who would not benefit from the fuel savings but might see an increase in their vehicle's range due to reduced air resistance at lower speeds.

Slow progress on electric mobility

The Swiss authorities' communication has been criticized for not addressing the potential of accelerating the transition to electric mobility as a solution to fossil fuel dependence. This lack of emphasis on electric vehicles is attributed to the country's ambiguous stance on electric mobility, which is linked to the political positions of some influential figures who are anti-electric vehicle.

Growth of electric vehicle adoption

Despite these challenges, the adoption of electric vehicles has been growing in Switzerland, with fully electric cars representing 26.2% of new car registrations in the first nine months of 2026, and 35.7% in September, a record high influenced by the cost of fuel. The proposed reduction in highway speed limits is only one of several hypotheses under consideration.

Proposed speed limit adjustments

The proposal suggests a 40 km/h reduction on all sections not already restricted by construction, tunnels, or traffic management. The number 80 km/h may be intended to make a more moderate reduction, such as 110 km/h, more acceptable. The situation remains under observation, as it could influence other neighboring governments.
