The Senate committee responsible for funding the Transportation Department approved on Thursday a plan that includes a number of provisions sought by some in the trucking industry, including a trailer-length amendment that sparked a lively debate and a couple of party-line defections before it was narrowly approved.

The Fiscal Year 2016 THUD bill (for the DOT, along with the Department of Housing and Urban Development) would provide $40 billion for federal-aid highway programs, the same as the 2015 budget—but that’s based on fuel tax receipts and contingent on a new surface transportation reauthorization, or an extension of MAP-21, being passed by July 31.

The DOT allotment is about $18 billion, slightly less than the current funding level and $3 billion short of the Obama’s administration’s request for the coming year. That includes $572 million for the Federal Motor Carrier Safety Administration (FMCSA).

The bill in many ways mirrors the House THUD bill, passed last month, including language that would extend the suspension of the 2013 restart provisions in the hours of service regulation pending further study.

The base package also features other trucking-specific policy riders, billed as “key safety provisions,” that require FMCSA to complete its final rule on electronic logging devices (ELDs) and its proposed rule on speed limiters.

“This [ELD] rule is critical to ensure that bad actors will not be able to falsify their records and will bring better and greater accountability to the trucking industry,” Sen. Susan Collins (R-ME), chair of the subcommittee that authored the bill, said in introducing it to the full committee.

The agency would have 60 days to publish the rule from the time the appropriation takes effect. If passed on schedule, the federal government’s fiscal year begins Oct. 1.

As for the speed limiters, Collins noted that FMCSA has delayed the rulemaking 21 times since 2011, “and it is time to get this rule completed.”

The THUD appropriation passed on a 20-10 vote, with dissent coming from Democrats who objected to the spending levels imposed by the current congressional budget agreement.
