What should be done to a gun before placing it in a vehicle?

The best practice before placing a gun in a vehicle is to ensure it is unloaded and stored in a gun case with the action open. This method enhances safety by reducing the risk of accidental discharge while in transit. Storing the firearm in a secured case not only protects the weapon but also prevents it from being accessed by unauthorized individuals, which is especially important in preventing theft or accidents.

Having the action open signifies that the firearm is not ready to fire, providing an additional layer of safety. This practice is critical in promoting responsible gun ownership and aligns with safe handling protocols advocated by various hunting and firearms safety guidelines. The other options do not adhere to these safety practices, which can lead to potentially dangerous situations.
