The “Hoy No Circula” (“No Driving Today”) program is designed to control the city’s vehicular circulation and thus reduce pollutant emissions.

It restricts the circulation of diesel- and gasoline-powered vehicles according to the day of the week and the last digit on the vehicle’s license plate, and is in effect between 5 am and 10 pm Monday to Friday, for all vehicles circulating in the city, whether they are local or not.
