As you are likely aware, many states allow the concealed carry of firearms (most requiring permits). Unfortunately, some firearm owners tend to “store” a handgun in the vehicle glove box. While this form of transport may be legal in your state (laws vary), this presents a serious concern if the firearm is present when the vehicle is brought in for service. For example, if part of the service involves replacing the cabin air filter, this involves accessing the glovebox. Of course, this concern isn’t limited to a glovebox. This applies to a firearm that is present in any area of the vehicle.
Even though the firearm may be possessed and stored legally, if you encounter a firearm in the vehicle, STOP. Do not touch the gun. One option might be to ask the customer to re-schedule the service visit at such time when the owner can deliver the vehicle with the gun removed.
Never allow a firearm to be handled in your shop by anyone (shop employee or vehicle owner). While the vehicle owner may not have intended to raise a concern, for future reference, politely inform the owner to be sure that any firearms are removed from the vehicle prior to visiting your shop. You may want to consult with your local police department and/or your attorney to establish a safety protocol that protects your shop from any potential liability.
Consider informing customers to please remove any firearms from the vehicle before any service appointments. The risk of unintended discharge is too great, and is to be avoided at all cost. Inform your technicians to never touch a customer’s firearm, and to alert the shop manager of the presence of a firearm immediately.
This has nothing to do with the right to (legally) bear arms. It’s simply a safety issue. Most responsible gun owners would never leave a firearm unattended, but there are many first-time gun owners who are oblivious to this basic safety concern.
