The Commercial Vehicle Safety Alliance also asked for the delay, and the Owner-Operator Independent Drivers Association agreed.
The changes, set to take effect July 1, restrict how drivers can use the optional 34-hour restart to reset their weekly driving limits of 60 hours in seven days, or 70 hours in eight days.
Drivers will be able to use the restart only once every seven days, and it must include two periods from 1 a.m. to 5 a.m.
Under the new regulation, drivers will also have to take a 30-minute break before driving more than eight hours continuously.
ATA has not yet asked the D.C. court to force FMCSA to delay the changes. Osiecki said the group is “currently considering our options” for court action.
