Starting Tuesday, Kansas is granting a yearlong exemption to small commercial trucks from most of the safety regulations it imposes upon larger haulers.

The Topeka Capital Journal reports that the exemption is the result of a new law. It was approved by the Legislature this year with large, bipartisan majorities at the urging of owners of landscaping, masonry and home-building businesses and trade groups.

They argued that smaller trucks shouldn’t face the same regulations as over-the-road semis.

But some state officials have misgivings.

The exemption will apply to trucks if their manufacturers specify that their weights when loaded are 26,000 pounds or less. Operators will avoid limits on hours they can be driven and requirements for tires, safety hitches, trailer braking systems or emergency equipment.
