Is it legal to carry a bottle of alcohol on the truck in a toolbox?

It's illegal and you will be fired.

 

No

 

The only alcohol legally allowed to be on a commercial vehicle, had best be in the trailer and had best have a bill of lading with it …Otherwise you’re in trouble.

 

You've got 3 different versions of "it's illegal." I don't need to add a 4th. Make sure you heed these words!

 

Wow.

 

In the OP’s case you are correct but generally there is one other condition where it’s legal under the FMCSR’s.
Question 3: Does the prohibition against carrying alcoholic beverages in §392.5 apply to a driver who uses a company vehicle, for personal reasons, while off-duty?

Guidance: No. For example, an owner-operator using his/her own vehicle in an off-duty status, or a driver using a company truck or tractor for transportation to a motel, restaurant, or home, would normally be outside the scope of this section.

 

Why not ask your safety director? You've already given your name, company name, and your image.

 

Maybe the safety director will ask him?
