The American Transportation Research Institute (ATRI) announced the start of its second phase of data collection on impacts from the recent changes to the Hours-of-Service (HOS) rules, which went into effect July 1, 2013. ATRI is asking commercial drivers to provide input on the changes through an online survey available on its website.

The survey asks drivers about impacts related to miles, pay and on-duty hours since the changes to the 34-hour restart (requirement of two periods between 1 a.m. and 5 a.m. and the limit of one restart per 7-day/168-hour time period) and the addition of the 30-minute rest break.

“Earlier this year we released a study quantifying potential impacts from the rules changes. This critical next step in the research will document how those expected changes are being experienced by drivers,” said ATRI President Rebecca Brewster.

ATRI will also initiate data collection from motor carriers to quantify productivity impacts resulting from the rules changes.

Drivers are encouraged to participate in the confidential survey here.

ATRI, based in Arlington, Va., is the trucking industry’s 501(c)(3) not-for-profit research organization. It is engaged in research relating to freight transportation’s role in maintaining a safe, secure and efficient transportation system.
