A bulletproof car would fall under the category of ”armoured vehicles”.

For the regulations on this, we would have to refer to the armoured vehicles section of the Alberta Vehicle Equipment Regulation, which is under the Alberta Traffic Safety Act.

Are bulletproof cars legal in Alberta?

Section 79.1 of the Alberta Vehicle Equipment Regulation states:

A person shall not drive or operate a motor vehicle that has been constructed or modified so that it protects its occupants from firearms or explosive devices if the motor vehicle, as a result of the construction or modification, is unsafe to operate or does not meet the other requirements of this Regulation.

Technically, it may be possible to modify or reenforce your vehicle to be bulletproof if the legal and safety criteria are met.

In Summary

• It is not legal to modify your vehicle to be bulletproof, if the modifications cause the driving or operation of the vehicle to be unsafe or in violation of Alberta vehicle regulations.
• It may be possible to make vehicle armour modifications legally if you stay within the laws.
