The Federal Motor Carrier Safety Administration is allowing an extra month for comments on its proposed electronic logging rule.

The Commercial Vehicle Safety Alliance, representing state police and other enforcement interests, had asked the agency for the one-month extension.

“This is a complex and significant rulemaking,” said CVSA Executive Director Stephen Keppler.

He said CVSA needs more time to understand the technology options in the proposal, and states need more time to evaluate its impact in the field.

In a notice to be published in the Friday Federal Register, the agency acknowledged CVSA’s concerns and said the comment period is extended from May 27 to June 26.
