Audit Initiated of DOT’s Oversight of Time Zones and Daylight Saving Time

Project ID: 

Since 2015, at least 45 States have proposed legislation either to change their observance of DST or to establish permanent standard time. For example, in recent years, three States have introduced bills to effectively adopt year-round DST by moving to an earlier standard time zone. However, DOT has not exercised its authority over time zone changes in over 10 years. Given recent State activity and the potential impact of time zone changes on transportation safety, DOT-OIG is initiating an audit with a limited scope to assess DOT’s processes for evaluating and responding to requests from States and localities for time zone changes and DST exemptions.
