How much cargo can protrude from the rear of a truck? Regulations 2026

How much can the cargo stick out from the back of the truck?

Basic rule – 2 meters maximum

The limit for how much cargo can protrude from the rear of a car is exactly 2 meters measured from the rear plane of the contour of the vehicle or combination of vehicles. This is a fundamental principle enshrined in Article 61(6) of the Traffic Law, which applies without exception to divisible cargo.

The measurement is taken from the rear contour of the entire vehicle. The rear load of a tractor-plus-trailer combination is measured from the rear edge of the trailer, not from the cab or the center of the vehicle. A standard semi-trailer is 13.6 meters long, which means that items up to 15.6 meters long fall within the two-meter limit.

A key distinction concerns the divisibility of cargo. The 2-meter limit on how much a load can protrude from the rear of a car applies to divisible loads. A finished roof truss, a complete machine or a turbine component are indivisible loads that can exceed the limit with the appropriate permit.

From what to measure properly?

The correct measurement of how much cargo can protrude from the rear of a car is questionable. The rear contour plane is a perpendicular plane through the most protruding parts of the rear of the vehicle.

Typical errors in measurement include:

• Counting from the rear axle instead of the rear wall of the vehicle (error by up to half a meter)
• Measure from the edge of an empty box instead of from a closed door or sideboard
• Skipping the boom of hooks or rubber bumpers (that’s also the outline of the vehicle)
• Measuring from the theoretical center of the vehicle instead of the actual rear end

A special exception applies for a stanchion trailer. The rear cargo of long timber can extend up to 5 meters behind the axle of the trailer, not behind its rear outline. This is an important difference that allows long logs to be transported.

Always measure from the rear bumper or box closure hooks. An error of 10-20 centimeters can determine a fine during an inspection.

Load dimensions in other directions

Although the focus is on how much cargo can protrude from the rear of the car, drivers also need to know the limits for other dimensions. The following rules complete the picture of complete legal requirements.

The maximum total width of the vehicle is 2.55 meters. The cargo at the rear of the vehicle can also protrude laterally a maximum of 23 centimeters on each side, giving a total width of up to 3 meters. The overall height is 4 meters, which requires route planning that takes into account overpasses and parking lots.

When is labeling required?

The threshold for mandatory marking is 0.5 meters. Cargo in the rear of the car protruding above this limit requires proper labeling, and failure to do so will result in a fine of 200 to 500 zlotys.

The regulations allow three alternative methods of labeling:

1. Red and white stripes directly on the cargo

A minimum of two stripes of each color (2 red + 2 white) with a total area of at least 1000 cm² as seen from the rear. The cargo at the rear of the car can be painted directly or wrapped with reflective stripes.

2. Straps on a disc attached to the load

Red and white stripes on a rigid shield attached to the rear face of the load. Cargo at the rear of the car marked in this way is more visible and easier to install than painting.

3. Geometric solid suspended at the end of the

A red and white cone or pyramid suspended from the most protruding point. The cargo at the rear of the car in this configuration is clearly visible from a distance.

Illumination at night and with limited visibility

Belts alone are not sufficient in low visibility conditions. Cargo at the rear of the car protruding at night, in fog or during precipitation requires additional lighting according to the following rules:

• Red light at the rear end of the load
• Red reflector not more than 40 cm from the edge
• White reflector on the front (if the load also protrudes from the front)
• Approved lighting, not ordinary bicycle lights

Lack of lighting by the load at the rear of the car at night is an additional fine of 200 to 500 zlotys. In total, you can receive a fine of up to 1,000 zlotys for lack of signage and no lights at the same time.

Transportation of indivisible cargo

Cargo in the back of a car exceeding 2 meters can be legally transported only if it meets the definition of indivisible cargo. Article 64 of the Traffic Law defines it as cargo that cannot be divided into smaller parts without disproportionate cost or risk of damage.

Examples of indivisible cargoes

• Finished roof trusses as a complete structure
• Agricultural or construction machinery as a whole
• Wind turbine blade
• Steel bridge construction
• Large energy transformer
• Precast concrete element

Absolute prohibition: an abnormal vehicle is not allowed to carry divisible cargo. Cargo in the back of the vehicle in the form of beams, which can be divided into smaller batches, must be within the limit of 2 meters. Carrying divisible cargo with an abnormal permit will result in heavy fines.

Requirements in abnormal transport

1. Pilotage when width exceeds 3 m or length 20 m
2. Speed limit in accordance with the permit category
3. Planned and approved route of travel
4. Notice of the road manager at bridges and overpasses
5. Proper security and marking of cargo

Fines for irregularities

The fine for failing to mark the cargo on the back of the car is between 200 and 500 zlotys. This is a fine imposed by the Police or ITD during a roadside inspection. Lack of night lights is another 200-500 zloty fine.

The administrative penalty is much harsher. Cargo in the back of a car exceeding the 2-meter limit without a permit will result in a fine of 6,000 to 15,000 zlotys, depending on the scale of the excess. The carrier, shipper and transport organizer are liable.

Additional implications:

• Stopping the vehicle pending reloading or obtaining a permit
• Delivery delay and additional downtime costs
• Revocation of license with gross or repeated violations
• Criminal liability when causing a traffic hazard

Securing the long load

Article 61(1) of the Traffic Law imposes an obligation to secure the cargo. The cargo in the rear of the car must be immobilized so that it cannot change position, fall out of the vehicle, obstruct the lights or limit the driver’s visibility.

Methods of securing long loads:

Approved transport belts

An essential tool for long loads. Rear cargo requires belts with LC (Load Capacity) parameters appropriate to the weight. Do not use worn or cut belts.

Chains with tensioners

For metal loads with sharp edges. Cargo at the rear of the car in the form of steel pipes or profiles requires cut-resistant chains.

Supports and wedging

Prevents sliding along the axle of the vehicle. The cargo at the rear of the car cannot swing while driving, braking or cornering.

Proper weight distribution

A long load heavier than the rear lifts the front of the vehicle. Cargo at the rear of the car requires redistribution of weight closer to the center of gravity for safe driving.

Find transportation for non-standard loads

Do you need to transport cargo in the back of your vehicle that exceeds standard dimensions? Long loads such as pipes, beams, planks, machinery or structural components require specialized vehicles. The Antrans BiS platform connects shippers with carriers with platforms, trailers, stanchion trailers and telescopic trailers.

Whether your rear-end cargo fits within the 2-meter limit or requires an abnormal permit, you’ll find the right carrier with experience in specialized transportation. Contact us and find out how simple it is to arrange professional transportation of long loads with full documentation service.
