Q&A - Limits to the Degree of Window Tinting?

Q&A ImageRegarding tinted windows on the rear side and back windows on cars: Are there any limits to the degree of tinting used? I can think of a neighbour of mine whose tinting looks almost black. It would make a difficult ‘over-the-shoulder’ look when changing lanes etc.



Here is a fairly complete overview of the legislation and standards for window tinting that apply to all vehicles in BC:

195(1)(b) A person shall not cause a vehicle to move on a highway if the view of the driver to the front or sides of the vehicle is obstructed.

7.05(1) No person shall drive or operate on a highway a motor vehicle the windshield or any window of which is in such a condition that the vision of the driver is impaired.

7.05(2) No person shall drive or operate a vehicle on a highway while his view of the highway or of any intersecting highway is unduly obstructed by any windshield sticker, sign, poster or any other thing or material placed over or affixed to the windshield or any window of the vehicle.


7.05(9) If a motor vehicle contains manufactured glass, tinting contained within the glass must meet the minimum light transmittancy requirements under the Canadian Motor Vehicle Safety Standards.


ANSI Standard Z.26 requires glass grades AS-1 and AS-10 for windshields and AS-1, AS-2, AS-10, and AS-11A for all other windows where driving visibility is required.


Each piece of glass installed in a vehicle manufactured on or after January 1, 1971 must be etched with the standard marking that it was manufactured to meet.


7.05(8) No person shall drive or operate on a highway a motor vehicle which has affixed to or placed on the windshield or a window any material that reduces the light transmitted through the windshield or window unless the material is affixed to or placed on

(a) the windshield but not more than 75 mm below the top of the windshield,

(b) a side window that is behind the driver,

(c) the rear window if the motor vehicle is equipped with outside rear view mirrors on the left and right side of the motor vehicle.


A vehicle’s high level brake lamp is often situated on the inside of the rear window glass.

4.04(1)(c) A stoplamp must not be obstructed by any material or by any part of the vehicle or load.

4.17(1) and must be visible on both sides of the vehicle at an angle of 45 degrees from the longitudinal axis of the vehicle.


219(1) A person shall not drive or operate a motor vehicle or trailer on a highway or rent a motor vehicle or trailer unless it is equipped in all respects in compliance with this Act and the regulations.

222 A person shall not sell, offer for sale, expose or display for sale or deliver over to a purchaser for use a motor vehicle, trailer or equipment for them that is not in accordance with this Act and the Regulations.

General prohibition

The last 2 sections 219(1) and 222 I find interesting.Who would be responsible for enforcement of those sections,specifically 222 which addresses the sale of non conforming vehicles.



The police or CVSE.
