Proposed European Citizens' Initiative: 30 km/h - making the streets liveable!
The EU has clear road safety and environmental goals but these are not yet met. A 30km/h (20mph) standard speed limit would help to implement them more efficiently as it has proven successful in reducing injuries and fatalities, noise, air pollution and CO2 emissions, and improving the traffic flow. People can travel with less fear. Environmentally friendlier modes become more attractive. To meet the subsidiarity principle, the local authorities must have the final decision to set other speed limits on their roads and implement equivalent alternatives to meet the goals.
