Speed limiters: DOT's math for 60, 65, 68 mphAug 29, 2016
The Dept. of Transportation has packed a lot of information into its 118-page Notice of Proposed Rulemaking to require speed limiting devices on heavy-duty vehicles.

Coming up, we’ll take a deeper dive into the data behind the proposal, and review the research on which DOT is basing the proposal.
