Oversized cargo transport is one of the most demanding tasks we face in logistics. Every transport of an oversized load is unique and brings specific challenges—from detailed route planning and securing escort vehicles to complying with strict safety regulations and coordinating with authorities. Thanks to modern technology, the expertise of our drivers, dispatchers, and other specialists, and our precise approach, HOPI is able to transport even the heaviest and largest loads with maximum efficiency. Read more about what oversized transport involves.
Oversized cargo, as the name suggests, refers to any load that exceeds the standard size or weight limits for road transport. Typically, oversized cargo is considered to be longer than 16.5 m (for a semi-trailer), wider than 2.55 m, higher than 4 m, or heavier than 40 tons.
From a logistics standpoint, it is important to note that oversized loads cannot be transported using standard trucks. They require specialized equipment such as low-bed trailers or high-load-capacity tractors. This also involves stricter safety and legal requirements, making oversized transport a demanding logistics discipline.
Oversized transport is categorized based on two main criteria: dimensions and weight. Each type of oversized cargo brings specific challenges and technical requirements for transportation.
Examples of oversized loads include:
Oversized transport is subject to strict regulations aimed at ensuring road safety and protecting infrastructure. In general, whenever you transport a load that exceeds standard dimensions, a permit is required.
Each EU member state has its own rules for oversized transport, but some principles are shared. Based on the planned route, you must obtain an individual permit valid only for a specific route and time period. Extremely oversized loads may also require escort vehicles or police supervision.
In the Czech Republic, rules for oversized transport are governed by Act No. 13/1997 Coll., on Roads. You must obtain a permit for "special use of roads," issued by the relevant administrative authority.
Which authority to contact? It depends on the type of roads used:
What must be submitted?
- purpose, scope, duration, and potential repetition of the transport
- route and schedule proposal
- vehicle details
- outline drawing of the vehicle or combination with the load
Oversized transport requires effective and careful route planning, which is more demanding than standard logistics. A detailed analysis of terrain, infrastructure, and possible restrictions is essential.
Unlike standard truck transport, the goal here is not minimizing fuel consumption or cost, but ensuring safe passage that fits both the load specifics and legal requirements.
Infrastructure isn’t always designed to handle extremely heavy and large loads. For heavy loads, it is necessary to verify the load capacity of bridges, viaducts, and roads in advance to prevent damage.
If the route passes through urban or densely populated areas, traffic peaks and restrictions must be considered. Oversized transport is often allowed only during night or early morning hours, and some routes must be pre-approved by local authorities.
Route planning must also consider seasonal conditions – not just for oversized transport. Snow, ice, floods, or road works can complicate transport, so it is important to stay informed.
Escort vehicles are an integral part of oversized transport, warning other road users and ensuring smooth passage. In complex situations – such as heavy or dangerous cargo or challenging road sections – police assistance may be required.
Besides detailed route planning, oversized cargo transport requires special equipment and advanced technologies to handle extremely heavy, long, tall, or wide loads.
Oversized transport uses equipment specifically designed for this purpose. For tall loads, we use low-bed trailers to reduce collision risk with bridges or wires. Extremely heavy loads are transported using modular transporters, which are assembled from modules according to load weight. Hydraulic chassis help maneuver in narrow streets, mountainous terrain, or difficult surfaces.
In addition to special vehicles, smart technologies are increasingly used in oversized transport. Trucks are commonly equipped with GPS tracking and telematics, allowing real-time monitoring and continuous assessment of narrow sections and obstacles.
Oversized transport is one of the most demanding logistics operations. It requires precise planning, special equipment, and expert knowledge from dispatchers and drivers to minimize risks.
The main challenge is safety risks, which may endanger the cargo, the driver, or other road users. Hazards include cargo overturning, due to sensitivity to sharp turns, speed changes, or uneven roads. Oversized cargo alters the vehicle's center of gravity and handling, increasing the risk of accidents.
Problems also arise if route analysis is insufficient or unexpected changes occur – e.g., unexpected obstacles like bridges or narrow roads could require rerouting or result in collisions.
Oversized transport also negatively affects the environment. Higher fuel consumption results from heavier loads and longer detours. This leads to increased carbon emissions. Solutions include using modern tractors with lower fuel consumption and gradual introduction of electric and hybrid trucks.
As stated throughout this article, oversized transport is complex and demanding, and should always be entrusted to experienced professionals. If you're selecting a reliable partner, devote sufficient attention to the decision.
