7. A vehicle covered by a special permit must be equipped with:
(1) an amber light operating at a rate of 60 to 90 cycles per minute that has a range of 360º and a lens at least 10 cm in height whose minimum width or diameter at that height is 12 cm. The light must be visible up to a minimum distance of 300 m in every direction not covered by the amber lights of an escort vehicle or by a light complying with paragraph 2;
(2) an additional light of the same type as that prescribed in paragraph 1, or 2 additional flashing amber lights with a minimum diameter of 17.50 cm, operating at a rate of 60 to 90 cycles per minute, at least 2.25 m apart, where the light installed in accordance with paragraph 1 is not visible in a direction not covered by the amber lights of an escort vehicle. The lights must be installed at least 1.5 m from the ground and be visible up to a minimum distance of 300 m in every direction for which they are required;
(3) boards or hard surfaces complying with the standards established in Schedule 2:
(a) where the width, including the load and equipment, exceeds 3.04 m, the length exceeds 25 m or the height exceeds 4.30 m;
(b) in the case of a vehicle used in snow removal, where the width exceeds 3.75 m, or where the equipment extends beyond the left side of the vehicle by more than 60 cm or beyond the right side by more than 130 cm, measured at the widest part of the vehicle, excluding its compulsory attachments.
Such traffic control devices must be placed at the front and rear extremities of the vehicle or of its load; they must be kept free of any object, substance or dirt and must be removed or covered when not required.
This paragraph does not apply to a vehicle covered by a Class 4 permit or a vehicle transporting trees loaded lengthwise or posts;
(4) square red or orange flags, in good condition, measuring 40 cm on each side, attached in at least 2 places so that they wave, or flashing amber lights. Those signals must be used where the load extends beyond the side of the vehicle by more than 30 cm. They must be installed at the widest place at the front and rear extremities of the load and at the front and rear extremities of overhangs extending beyond the width of the load by more than 30 cm and, in the case of posts extending beyond the rear of the loading platform by more than 4 m, every 2 m along each side of the stack of posts extending beyond the rear of the loading platform.
At night, from 28 February 1994, the flags must be replaced by flashing amber lights.
The lights must have a minimum diameter of 10 cm, operate at a rate of 60 to 90 cycles per minute and be visible up to a minimum distance of 150 m. The lens must be designed so as to allow lateral vision of the light.
All signals must be installed so that they do not widen the load or the overhangs by more than 12 cm on either side. Notwithstanding the foregoing, the signals intended for the extremities of the load may be arranged in accordance with section 10 in the case of a Class 2 permit; in the case of a lowered semi-trailer, where the load and overhangs that must be signalled are placed lengthwise within the loading platform, those signals may be positioned at the junction of the raised and lowered portions of the semi-trailer. If so, they must be installed on the sides beyond the width of the load and overhangs, without increasing that width by more than 12 cm;
(5) in the case of posts or trees loaded lengthwise, the vehicle must also be equipped with a red light with a minimum diameter of 10 cm, visible up to a distance of 150 m and installed at the extremity of the rear overhang.
