Quick Answer
In Washington, you must have a valid CPL to carry a loaded handgun in your vehicle. If you do not have a license, the handgun must be strictly unloaded and locked out of reach. Furthermore, whether you have a permit or not, any firearm left inside an unattended vehicle must be securely locked up and completely hidden from view.
The Controlling Statutes
Washington heavily regulates firearms in transit. The state enforces a clear divide between carrying on your person and leaving a weapon in your car.
RCW 9.41.050(2)
Vehicle Carry Requirements
A person shall not carry or place a loaded pistol in any vehicle unless they possess a CPL and either keep the pistol on their person, or the person with the CPL is present in the vehicle.
RCW 77.15.460
The Loaded Long Gun Ban
It is strictly illegal to have a loaded rifle or shotgun in a motor vehicle. Washington defines "loaded" broadly—a long gun is legally considered loaded if there is a loaded magazine attached to the firearm, even if the chamber is empty.
The Unattended Vehicle Mandate
Under RCW 9.41.050(3), you cannot legally leave a pistol in a vehicle unattended unless you meet two strict criteria: 1) the pistol is locked within the vehicle, AND 2) the pistol is concealed from view from outside the vehicle. If you run into a convenience store and leave your gun sitting openly on the passenger seat of your locked car, you are committing a crime.
Washington Compliance Storage Safes
Because Washington law explicitly criminalizes leaving a visible firearm in an unattended vehicle, you must ensure your gun is securely hidden. A tethered vehicle safe allows you to stay legally compliant and immune to smash-and-grab theft.

Duty to Inform Law Enforcement
Washington is an "Upon Demand" state. There is no law requiring you to immediately notify an officer that you have a loaded firearm in your vehicle when pulled over for a traffic stop. However, if a police officer explicitly asks if there are weapons in the vehicle, or asks to see your Concealed Pistol License, you must answer truthfully and produce your CPL and ID.
Frequently Asked Questions
Can out-of-state visitors carry a loaded gun in their car in Washington?
Only if they hold a permit from a state that Washington formally recognizes. Washington does not honor many out-of-state permits (for example, Oregon permits are not honored). If your permit is not recognized, the firearm must be unloaded and locked in the trunk.
