The National Institute of Traffic and Land Transportation ( INTRANT), is the government agency of the Dominican Republic in charge of planning, regulating and supervising the mobility system, land transit and public and private transportation throughout the national territory. Among its main responsibilities are the issuance and renewal of driver's licenses, the control and management of the traffic light network, the development of mobility and road safety policies, as well as the supervision of land transportation and associated services.[1]​[2]​ It is attached to the Ministry of Public Works and Communications "Ministry of Public Works and Communications (Dominican Republic)").[3]​.

This institution also administers vehicle regulations and the operation of the corresponding authorities, such as road enforcement agents and transportation control units.[4]​ Currently, the executive director of the agency is Milton Morrison, appointed by presidential decree in 2024.[5][6]​.

The legal framework that gave rise to the National Institute of Traffic and Land Transportation was established with the promulgation of Law 63-17 on Mobility, Land Transportation, Transit and Road Safety of the Dominican Republic in February 2017.[7]​ Said legislation restructured the Dominican land transportation system and grouped together various institutional functions.[8]​.

Before its creation, the regulation of transportation and traffic was dispersed among different organizations, such as the General Directorate of Land Transit, the Land Transportation Development Fund (Fondet) and the Council for the Administration and Regulation of Taxis (CART). The new legislation made it possible to centralize powers to improve institutional coordination.[9][10]​.

INTRANT began its formal operations in June 2017 with the objective of modernizing and reorganizing the public transportation system, promoting sustainable mobility solutions and strengthening road safety mechanisms in the country's main cities.[11]​.

The agency has focused its actions on the restructuring of urban and interurban public transportation services, the modernization of licensing and permit processes, and the implementation of pilot plans to improve the traffic light network and bus routes. Road education projects were also initiated aimed at reducing road accidents.[12]​ It has executed traffic reorganization plans, regulatory reforms and technological expansions in order to promote more efficient, safer mobility and oriented towards sustainable urban development in the Dominican Republic.[13][14]​.
