of the 2014–15 winter, Baker started a $30 million pothole repair fund in March 2015 and filed the state's annual $200 million bill to the state legislature for infrastructure funding aid to local governments through the state's Chapter 90 program (which was approved the following month). In June 2015, Baker submitted a $2.13 billion capital budget for fiscal year 2016. In October 2015, Baker and the state's Division of Insurance approved a proposed insurance policy by USAA to provide additional coverage to current policyholders who are employed as transportation network company drivers.

In May 2016, Baker submitted a $2.19 billion capital budget for fiscal year 2017, and the following month, Baker's administration launched a multi-faceted initiative to reduce motor vehicle accidents during the upcoming summer. After proposing similar legislation the previous year, in August 2016, Baker signed into law a bill regulating transportation network companies by implementing a 20-cent per ride company surcharge, mandating vehicle insurance requirements, and background checks for company drivers. Also in August 2016, Baker vetoed a pilot program for a vehicle miles traveled tax, and Baker signed into law a bill that expanded a program to improve local street network safety and efficiency that was launched earlier that year, authorized $50 million in spending over the subsequent five years for repairs to small municipal bridges, and included a $750 million authorization request for the federal aid highway program. In October 2016, Baker issued an executive order to create a regulatory framework for the testing of driverless cars in Massachusetts, and in the same month, oversaw the opening of the state's electronic tolling system along the Massachusetts Turnpike. In April 2017, the Massachusetts Department of Public Utilities released data showing that more than 8,000 of the 70,000 drivers for transportation network companies who applied failed to pass the state background check requirement signed into law by Baker the previous August. In May 2017, Baker signed into law the annual Chapter 90 funding request, which came to $290 million so as to include funding for a software platform for the state Registry of Motor Vehicles and to reauthorize a mobility assistance program, and Baker submitted a $2.26 billion capital budget for fiscal year 2018.
