Quick Answer
In Massachusetts, you must have a valid License to Carry (LTC) to have a loaded handgun in your motor vehicle. The loaded handgun must remain under your direct control while in the vehicle. If you step out of the car, the firearm must be completely unloaded and secured in a locked container or trunk.
The "Direct Control" Trap
Even if you have successfully jumped through the hoops to acquire a Massachusetts LTC, the state's transport laws are riddled with easily violated storage technicalities.
M.G.L. c. 140 § 131C(a)
Direct Control Law
A person with an LTC shall not carry a loaded firearm in a vehicle unless the loaded firearm is under their "direct control." This generally means holstered on your person or within immediate, uninhibited reach.
Unattended Storage Mandate
Unload and Lock
If the gun leaves your direct control (e.g., you park and walk into a store), it must be unloaded and secured in a locked container. Locking your car doors is not enough. The container must require a key or combination.
Large Capacity Rifle & Shotgun Bans
Under M.G.L. c. 140 § 131C(b), no person may possess a "large capacity" rifle or shotgun in a vehicle unless the firearm is strictly unloaded and secured in a locked container at all times, even while you are driving. You cannot legally have a loaded AR-15 resting in the back of your vehicle under any circumstances in Massachusetts.
Massachusetts "Locked Container" Compliance
Massachusetts law explicitly demands that any firearm not under your direct physical control must be unloaded and locked in a secure container. A tethered vehicle safe is the most effective way to satisfy M.G.L. c. 140 § 131C without resorting to a cumbersome trunk lockbox.

No Duty to Inform Law Enforcement
Massachusetts is a "No Duty to Inform" state. There is no specific state statute requiring you to immediately notify an officer that you have a loaded firearm in the vehicle when you are pulled over for a traffic stop. However, any time law enforcement runs a Massachusetts vehicle registration or driver's license, your LTC status is visible on their terminal. If the officer asks if you are armed, lying will lead to severe complications.
