Singapore will stop issuing new vehicle permits starting February 2018. The government points to limited space available in the city-state as the reason for the halt in vehicle growth. They plan to reduce the vehicle growth rate from 0.25 percent per year to 0 percent for cars and motorcycles. Due to the limited space available, Singapore controls the number of vehicles on the road to a great degree.
