  Mexico City has a large road network, and relatively high private car usage, estimated at more than 4.5 million in 2016. There is an environmental program, called Hoy No Circula ("Today Does Not Run", or "One Day without a Car"), whereby vehicles that have not passed emissions testing are restricted from circulating on certain days according to the ending digit of their license plates, in an attempt to cut down on pollution and traffic congestion.
