Hauling Oversize Freight

How wide can a trailer be in canada?

 

In the realm of highway travel, hauling oversized freight occupy a unique space because they exceed the standard legal width limit of 8.5 feet. This isn’t just a trivial measurement; it’s a defining boundary that requires specialized transportation solutions. Oversize loads, on the other hand, take “big” to a whole new level by surpassing legal limits in width, length, height, or weight.

Understanding this distinction is crucial. These oversized loads demand specific equipment, like flatbed trailers, to ensure safe and efficient navigation on our roads. It’s not just about transporting goods; it’s about mastering the intricacies of logistics and adhering to legal standards to keep our highways safe and operational.

By recognizing the nuances of these transportation challenges, we can better appreciate the importance of specialized solutions in maintaining the functionality and safety of our highway systems.

 

Definition and Characteristics wide load vs oversize

 

It refers to cargo that exceeds the standard legal limits for weight, height, length, or width. These wide loads and oversized heavy haul loads are typically larger than the dimensions allowed on flatbed trucks travelling on public roads without special oversize overweight permits and escort vehicles.

They both can vary significantly in size and shape. This can include heavy machinery transport, construction equipment transportation, and even pre-fabricated structures.

The key characteristic is that it exceeds the legal limits set by transportation authorities is the following.

  • 12 feet, 6″  high
  • 14 feet, 6″ in wide
  • 52,000 lbs

 

Legal Requirements and Regulations

 

Transporting oversize and overweight freight is a complex task, governed by strict legal regulations in most countries. In Canada, these heavy haul regulations are designed with a singular focus: to ensure the safety of both the cargo and everyone else on the road.

Navigating these rules is crucial for any business involved in heavy haul transport. Compliance isn’t just a legal requirement; it’s a commitment to safety and efficiency. By adhering to these regulations, companies can avoid costly fines, ensure timely deliveries, and, most importantly, protect lives on the road.

In the world of heavy haul transport, understanding and following Canadian regulations isn’t just a box to check—it’s a cornerstone of responsible and successful operations.

Key legal requirements include:

Weight Limits: Most regions have strict weight limits for oversized loads to prevent excessive strain on roadways and bridges.

Dimensional Limits: In addition to weight, there are limits on the dimensions of wideload transport. This includes restrictions on width, height, and length.

Common Types of Oversized Loads

It can encompass a wide range of cargo, including:

Infrastructure Considerations: The weight of oversized loads can damage roads, bridges, and other infrastructure if not properly managed.

Definition and Characteristics

Now, let’s dive into the world of wide loads. It’s cargo that surpasses the standard width limits set by transportation authorities.

While oversized loads can exceed legal dimensions in various ways—length, height, or weight—wide loads are specifically about width. This distinction is critical for planning the logistics and securing the necessary permits. Understanding this can help you navigate the complexities of transport regulations more effectively and ensure your cargo moves safely and efficiently.

 transportation is also subject to stringent legal requirements, including:

  • Maximum Width Allowances: Regulations dictate the maximum width allowed, typically  requiring wide load permits and safety precautions when exceeding these limits.
  • Markings and Escorts: often require specialized markings and escort vehicles to alert other road users and ensure safe transport.

Common Types

Modular Homes: Transporting modular homes, which are often wider than standard cargo.

Wind Turbine Blades: These exceptionally long and wide components require specialized transport due to their dimensions.

Heavy haul transportation presents its own set of challenges and risks, including:

  • Traffic Disruptions: These loads can slow down traffic significantly and require careful planning to minimize disruptions.
  • Clearing Obstacles: Navigating through narrow roads and obstacles like traffic signals and signs can be particularly challenging.

Key Differences

Be prepared to adapt to rules for oversize heavy haul with new technologies, regulations, and environmental considerations as you continue to transport loads efficiently and responsibly.

The Weight and Dimension Limitations as per the Highway Traffic Act (HTA)

When a vehicle’s dimensions or weight go beyond the standard legal limits, securing an oversized/overweight permit is a must.

Here’s a quick breakdown of the weight and dimension restrictions set by the HTA. For more in-depth information, refer to the specific sections of the HTA.

If your transport needs exceed the limits allowed by the HTA, consider alternative modes of transportation like rail, air, or water. Exploring these options can help you stay compliant and ensure your cargo reaches its destination safely and efficiently.

Maximum Width:

The maximum allowable width for a vehicle, including its load, is 2.6 meters.

Exceptions:

– Raw forest products (while en route) may have a width of up to 2.8 meters.
– Road service vehicles, as defined in Part X of the HTA, and such vehicles when traveling to and from a maintenance site or repair center, have no specified width limit.
– Loose fodder, including rectangular and round bales of hay, do not have a specified width limit.

Maximum Length (Single Vehicle):

A single vehicle, including its load, is permitted to have a maximum length of 12.5 meters.

Exceptions:

– This limitation does not apply to fire apparatus, semi-trailers, or articulated buses.

Maximum Length (Semi-trailer)

The length of a semi-trailer, including its load, must not exceed 16.15 meters (for SPIF) or 14.65 meters (for NON-SPIF, which stands for Safe, Productive, Infrastructure-Friendly).

Definition of Semi-trailer 

A semi-trailer is a type of vehicle towed by another, designed so that a significant portion of its weight and load is supported by the towing vehicle or a trailer converter dolly through a fifth wheel assembly.

Crucially, any length added by auxiliary equipment or machinery not intended for carrying a load doesn’t count towards this measurement. This distinction is key for understanding how semi-trailers operate within legal and logistical parameters.

Maximum Length (Combination of Vehicles)

The total length of a combination of vehicles and their oversize heavy haul loads should not exceed 23 meters.

Maximum Height

The combined height of a vehicle and its load must not exceed 4.15 meters.

Maximum Weight

Weight limits are based on axle configurations and spacings. If your vehicle exceeds the limits set by the HTA, you need an oversize/overweight permit.

For comprehensive details on weight and dimensions, check out the Highway Traffic Act Regulation 413/05 – Vehicle Weights and Dimensions. It focuses on ensuring vehicles are safe, productive, and infrastructure-friendly.

Implements of Husbandry:

Oversize/overweight farm machinery, farm tractors, and self-propelled implements of husbandry (SPIH) carried on a plated motor vehicle or plated trailer drawn by a motor vehicle require an oversize/overweight permit.

It’s important to note that oversize loose fodder, such as hay bales, does not require a permit in accordance with HTA 109(2)

REDUCIBLE LOAD OVERWEIGHT POLICY

Producers or shippers are eligible to enter into agreements to operate wide load trucks which exceed the weights and/or dimensions identified in the Commercial Transport Regulations (CTR) when carrying reducible loads using vehicle configurations depicted in the Appendices to the CTR, and under the following conditions:

  • The commodity must be capable of being hauled using vehicle combinations at legal weights and dimensions as identified in the CTR,
  • The haul proponent is responsible for all studies as may be required to confirm:
    • the proposed vehicle configuration complies with recognized vehicle dynamics performance and safety thresholds at the requested weights, and
    • bridge capacities and any upgrades, if necessary to accommodate the haul vehicles at the requested weights,
  • The haul proponent will be responsible for paying any costs associated with upgrading infrastructure to accommodate the haul,
  • The haul must generate a minimum of 5% reduction in Equivalent Single Axle Loadings (ESAL) when compared with the ESAL count which would be generated by the haul using a comparable Super B-train at legal weights and dimensions, according to the process outlined in section 6.5.1.
  • If the haul is approved, the shipper will be required to ensure that anycarrier operating pursuant to this agreement will:
    • comply with any pilot car requirements or other travel conditions resulting from the approved dimensions of the configuration and load (see Form CVSE1000),
    • complement a system for monitoring axle and gross vehicle weights, and make the vehicle weight information available to Ministry staff as required to audit compliance,
    • develop, document and demonstrate a driver training and monitoring program which is specific to the haul,
    • install electronic technology, including electronic driver logs, speed monitoring for each driver and vehicle on the haul, and
    • maintain a “Satisfactory” rating under the National Safety Code
  • If the vehicles operate on highways which have inspection stations which are part of the Weigh2Go network, all vehicles operating pursuant to the agreement must be registered and maintain participation in the Weigh2Go program.

    Application

    This program reviews applications to haul reducible loads exceeding the legal limit of 63,500 kg and up to 27.5 meters in length. It operates on the premise that you already have the option and ability to transport the commodity within legal weights and dimensions without needing extra permits or analysis.

    As such, all haul costs are compared to the legal haul option, with any additional assessment and infrastructure costs being the applicant’s responsibility. This ensures that all extra expenses are clearly understood and accounted for by those seeking to exceed standard limits.

    REDUCIBLE LOAD OVERWEIGHT POLICY CANADA

    Every route must be meticulously reviewed to ensure bridges and pavements can handle the bulk haul. If consultant work is needed to evaluate bridge or pavement capacities, those costs fall on the haul proponent.

    Safety is paramount. All vehicles must be deemed safe for the proposed route. Any new configurations or changes in weight/dimensions must be assessed to meet recognized vehicle dynamics performance and safety standards. Again, any consultant costs for these assessments are the responsibility of the haul proponent.

    The proposed haul must produce an ESAL count that is at least 5% less than what would be generated if using a comparable legal B-train configuration.

    Special safety considerations apply to bulk liquid transport (tankers). Before starting such a proposal, consult with the Senior Vehicle Engineer, CVSE. Contact details are in the downloadable heavy haul overweight permits PDF below.

    A Qualified Professional must conduct and sign off the ESAL comparison. This involves comparing the ESALs generated by moving one million tonnes of payload with a standard ‘Super B Train’ (8-axle B Train) combination to those generated by your proposed vehicle combination.
