Truck drivers who split their day between CHP-regulated and unregulated duties: only the unregulated hours count toward daily/weekly overtime

Summary Employer counsel wrote to confirm DLSE's enforcement policy on overtime for truck drivers who spend part of the day performing duties regulated by the California Highway Patrol under Title 13 of the California Code of Regulations and part of the day performing unregulated work. DLSE confirmed the description was accurate: hours worked under CHP-regulated duties are not counted toward the employer's overtime liability, but any unregulated hours exceeding eight in a day, or forty in a week, must be paid at the applicable premium rate. DLSE also enclosed an addendum updating Interpretive Bulletin 87-5 to reflect then-current law.

Re: Hours of Work of Truck Drivers

Dear Mr. Dixon:

In response to your letter of March 1st, please be advised that you have accurately described the enforcement policy of the Division in regard to the overtime requirements for drivers. As you state, with respect to a driver who spends part of the day doing work which is not subject to regulation by the California Highway Patrol, and part of the day doing work which is of a type such that the hours of work are regulated by the California Highway Patrol, the hours worked in the performance of duties regulated by Title 13, C.C.R., are simply not counted toward the overtime liability of the employer.

However, I should point out that any work in any one day which is unregulated by Title 13 of the Code of Regulations which exceeds eight must be paid for at the applicable premium wage. Additionally, any such hours in excess of forty in one week must, likewise, be compensated at the appropriate premium rate.

I am taking the opportunity to attach an addendum to Interpretive Bulletin 87-5 issued January 18, 1991, which updates that Bulletin to conform to current law.

Thank you for your interest in California Labor Law.

Yours truly,

H. THOMAS CADELL, JR.
Chief Counsel
