Now people will drive 120 km per hour because people were already driving 110 plus when the limit was 100.
Under the leadership of Premier Ford, our government is helping to increase travel costs, emissions and the risk of getting killed on our highways.
Driving at 110 km/h instead of 100 km/h directly increases fuel consumption and emissions by 10% per distance travelled and the risk of fatal collisions by 20%.
Fuel Consumption and Efficiency:
10% increase in fuel use: Reducing your speed from 110 km/h to 100 km/h decreases fuel consumption by roughly 10%. Conversely, pushing up to 110 km/h burns more fuel over the same distance.
Aerodynamic drag: Exponentially higher air resistance at 110 km/h forces the engine to work harder.
Financial and environmental impact: Higher consumption raises fuel costs for drivers and increases tailpipe carbon emissions.
The 20% Metric: A study in the journal Sustainability found that for every 10 km/h increase in speed limits on highways, fatal collisions increase by more than 20%. [1]
Crash Energy: Modest increases in speed produce disproportionately large spikes in kinetic energy, which causes more severe blunt-force trauma to vehicle occupants.
