M.R. 104/2023 Signs on overdimensional vehicles 40(1) A permit may require an overdimensional vehicle or vehicle carrying an overdimensional load to carry a "WIDE LOAD", "LONG LOAD", "OVERSIZE LOAD" or "D" sign. 40(2) If a permit requires an overdimensional vehicle or vehicle carrying an overdimensional load to carry one of the signs described in subsection (1), the permit holder and the vehicle's driver and operator must ensure that (a) the sign meets the specifications for the type of sign set out in Schedule E; and (b) the sign is mounted in a conspicuous position. Clearance lamps for travel during the nighttime 41(1) When a permit authorizes an overdimensional vehicle or vehicle carrying an overdimensional load to be driven during the nighttime, the permit holder and the vehicle's driver and operator must ensure that the vehicle is equipped with the following clearance lamps mounted in a conspicuous position as near the top of the vehicle or its load as is practicable: (a) two lamps, each of which casts an amber light visible from an oncoming vehicle, one located on the left side and one on the right side of the front of the vehicle or its load; (b) two lamps, each of which casts a red light visible from a vehicle approaching from the rear, one located on the left side and one on the right side of the back of the vehicle or its load; (c) two lamps, each of which casts an amber light visible from an oncoming vehicle and a red light visible from a vehicle approaching from the rear, that are so positioned that one is on the portion of the vehicle or its load that projects furthest to the right and one is on that portion of the vehicle or its load that projects furthest to the left. 41(2) When subsection (1) applies to a vehicle, the permit holder and the vehicle's driver and operator must ensure that the clearance lamps are lighted when the vehicle is driven on a highway during the nighttime. Warning lamp 41.1(1) An overdimensional vehicle or a vehicle carrying an overdimensional load operated under a permit may be equipped with a rotating, oscillating, pulsating or flashing amber lamp and the vehicle's driver or operator may operate the lamp on a highway. 41.1(2) The permit may require the vehicle to be equipped with a rotating, oscillating, pulsating or flashing amber lamp and may require the vehicle's driver or operator to operate the lamp on a highway. M.R. 104/2023 Pilot vehicles 42(1) When a permit requires an overdimensional vehicle or vehicle carrying an overdimensional load to be escorted by a pilot vehicle, the permit holder and the vehicle's driver and operator must ensure that — except as otherwise provided in the permit — the vehicle is escorted by a pilot vehicle and that the pilot vehicle complies with this Part and has the equipment and sign required by it. 42(2) A pilot vehicle must be a motor vehicle (a) the height of which is such that (i) the bottom edge of a top-mounted sign sits (A) not more than 5 cm above the roof of the vehicle, and (B) not less than 1.6 m and not more than 2.5 m above the road surface, and (ii) when a sign is mounted as required under subclause (i), the sign is visible to other traffic from the front and the rear; and (b) that is large enough and has sufficient load-carrying capacity to carry the equipment and sign that this Part or the permit requires. 42(3) A pilot vehicle must not tow another vehicle. Equipment and signs on pilot vehicles 43(1) A pilot vehicle must (a) be equipped with a hands-free communications device that allows the pilot vehicle's driver to communicate with the driver of the overdimensional vehicle or vehicle carrying an overdimensional load; (b) be equipped with a stop/slow paddle, high visibility safety apparel, protective headwear and a flashlight that comply with subsection 20.6(2) of the Workplace Safety and Health Regulation , Manitoba Regulation 217/2006; (c) be equipped with a fire extinguisher that complies with National Fire Protection Association Standard NFPA 10, Standard for Portable Fire Extinguishers and is in good working order; (d) be equipped with flares or reflectors for hazard warning that (i) are visible from a distance of 150 m under normal atmospheric conditions, and (ii) conform to any standards that apply to them under the Act; (e) be equipped with at least one roof-mounted flashing amber lamp that, when lighted, is capable of emitting a beam of light clearly visible from a distance of 300 m in normal daylight and is in good working order; and (f) when escorting an overdimensional vehicle or vehicle carrying an overdimensional load that is required by permit to have a sign mentioned in section 40, must carry a sign that meets the requirements of subsection (2). 43(2) The sign required by clause (1)⁠(f) must (a) be constructed of durable material suitable for use of the sign in all weather and highway conditions; (b) comply with the requirements for design, colour and dimensions set out in Schedule F; (c) be evenly illuminated so that each face of the sign is clearly visible from a distance of 300 m in the ambient lighting conditions in which the pilot vehicle is being operated; (d) have a sign box that is sheltering all wire connectors, switches, flashers and similar wiring components for the wiring attached to the sign; (e) if the maximum luminance is more than 100 cd/m 2 , be adjustable to a nighttime setting of 100 cd/m 2 or less; (f) have mounted on it two outboard amber lamps (one at each end) that (i) comply with Society of Automotive Engineers Standard J595, Directional Flashing Optical Warning Devices for Authorized Emergency, Maintenance and Service Vehicles , and (ii) flash in unison; (g) have mounted on it two inboard rotating lamps or strobe lamps (one on each end) that (i) operate only when adverse weather and highway conditions are encountered, and (ii) comply with Society of Automotive Engineers Standard J845, Optical Warning Devices for Authorized Emergency, Maintenance, and Service Vehicles ; (h) have separate circuits to prevent simultaneous operation of the two lighting systems described in clauses (f) and (g) and be controlled by a three-way on-off switch; (i) be designed to mount on car-top carriers or a comparable mounting method; (j) be capable of being covered, blacked out or folded down when not in use; and (k) be securely attached to the pilot vehicle. M.R. 32/2019 ; 104/2023 Prohibition on misuse of signs 44 A person must not drive or operate on a highway a vehicle or a combination of vehicles displaying a sign indicating the presence of an overdimensional vehicle or vehicle carrying an overdimensional load unless the person is (a) driving or operating an overdimensional vehicle or vehicle carrying an overdimendsional load; or (b) driving or operating a pilot vehicle that is escorting an overdimensional vehicle or vehicle carrying an overdimensional load. Proximity of pilot vehicle to escorted vehicle 45 A person driving or operating a pilot vehicle that is escorting an overdimensional vehicle or vehicle carrying an overdimensional load must (a) precede or follow the escorted vehicle, as set out in the permit; and (b) stay within a distance from the escorted vehicle that is (i) between the minimum and maximum distance set out in the permit, or (ii) if the permit does not stipulate a minimum and maximum distance, a distance that is reasonably prudent considering the speed of the escorted vehicle, the presence of other traffic, and the prevailing highway conditions. For certainty, a permit may require one pilot vehicle to precede the escorted vehicle and a second pilot vehicle to follow the escorted vehicle. 46 [Repealed] M.R. 104/2023 PART 10 47 [Repealed] M.R. 32/2019 PART 11 REPEAL AND COMING INTO FORCE Repeal 48 The Vehicle Weights and Dimensions on Classes of Highways Regulation , Manitoba Regulation 575/88, is repealed.
