Overloading of Vehicles & Trailers (2023)

Overloading a vehicle is not difficult to understand if you follow the guidance, and it is not always the case that drivers are aware of how to load correctly. However, it is an offence under the Road Traffic Act and carries a maximum penalty of up to £5,000 per offence, which could be as a result of overloading in connection with an axle (or axles), the gross vehicle to or the train weight of the vehicle.

Overloading Convictions

If a vehicle is stopped at a routine checkpoint and found to be overloaded, it will depend on the severity of the amount the vehicle is overloaded. Anything less than 5% will be treated as a minor overload, the driver will be cautioned and it may be that he/she will be allowed to continue, or will be requested to have the excess load removed before continuing the journey.

If the overload is serious, the overload will be requested to be removed. This is an offence and the driver and O Licence Operator will be prosecuted.

In some instances, the overload may only be on an axle, but the gross vehicle weight is not exceeded. In cases like this, the driver will be expected to re-position his/her load to comply with the axle weights of the vehicle, although it will likely be noted by the enforcement officer and it is likely that the offence will be included in the operators OCRS (Operator Compliance Risk Score).

There are two statutory defences regarding the overloading of vehicles, which are that it must be shown that:

(Video) 36 Worst Overloaded Trucks and Car Compilation 2021 Part.1

  • the vehicle was proceeding to the nearest available weighbridge to be weighed, or was proceeding from the weighbridge to the nearest suitable offloading point, or,
  • that the vehicle was loaded to within its legal limits and the weight (either gross, train or individual axle) had increased in transit by no more than 5% and nothing had been added to the vehicle since it was first loaded.

It must be remembered that overloading convictions can affect the decision of the Traffic Commissioner to suspend, revoke or renew a driver's vocational licence. If an operator and/or his driver is convicted of overloading, details of that conviction must be notified to the Traffic Commissioner or Traffic Area Office within 28 days of the offence being committed.

Overloading convictions may be taken into account by the Traffic Commissioner who may decide to take action against the Licence Holder. It should be remembered that when applying for an Operator’sLicence the authorities must be satisfied that the applicant has made acceptable arrangements to avoid overloading as per the undertakings onthe online application wheninitially applying for the Operator’s Licence.

If a vehicle has been overloaded, the driver and operator may be charged with the offence of using a vehicle in a dangerous condition, as the vehicle would no longer comply with certain parts of the Construction and Use Regulations 1986.

Overloading and the problems created by doing so

Overloading causes problems and likely consequences other than the obvious injury or potential loss of life to the driver, loading/unloading staff, other road users or the general public. The resultant problems caused by overloading any vehicle are that it:

  • significantly impairs the driver's ability to brake and steer correctly
  • causes excessive wear and damage to roads, bridges, and pavements etc.
  • increases undue strain on tyres with the risk of tyre failure
  • causes the vehicle to be wholly unstable, especially on corners or at roundabouts
  • is consequently unfair competition for other hauliers
  • means the vehicle may become uninsured as the act of overloading is illegal

Overloading is not only a problem for larger goods vehicles, it is equally a problemforsmaller vehicles, such as vans, cars and passenger carrying vehicles.

The additional problems of overloading will hit the bottom line of all operators, as overloaded vehicles if stopped:

  • will not be able to continue their journey until the overload problem is rectified
  • the high penalties incurred for being overloaded are high
  • may be clamped and not allowed to move until theoverload situation is rectified and the release fee is paid
  • money and manpower will be incurred to have the excess load removed

Preventing overloading

Overloading a vehicle, whether a goods vehicle, Passenger Service Vehicle (PSV) or car, is illegal. Preventing a vehicle(s) being overloaded is not difficult and procedures should be put in place as a policy of best practice.

Companies should have a "safety culture" in place which ensures that drivers understand weight legislation and immediately report any concerns that a vehicle is illegally overloaded to their manager. Their manager should investigate all concerns immediately to prevent overloading.

Putting a policy of best practice in place may seem an obvious solution, but does not always exist. Operators should not assume that drivers and warehouse staff know what is safe to load, as for the majority of general hauliers, their drivers will be loading from manufacturers or warehouse distributors etc.

Problems can occur when loading at customer's premises where (through human error) the weight of the consignment note may be incorrect. Equally so, it may be the case that a client, or agent merely wants the whole consignment to be loaded and does not consider the weight implications that may follow.

Whatever the case, a policy of vigilance must be foremost at all times.

VehiclesandWeight Checks

DVSA employees, trading standards officers, and police officers carry out random checks at the roadside to enforce overloading regulations. It should be noted that these are carried out regularly, especially by the DVSA, who do so at all checkpoints.

It should also be noted that there are Weigh In Motion Systems (WIMs) strategically in place throughout the UK road network.

Vehicle Overloading

The weight limits displayed on either the manufacturers’ plate or ministry plate are determined by the technical specification of the vehicle and the need to protect GB roads and bridges from excessive wear.

Vehicles are permitted to operate at weights above 44 tonnes in exceptional circumstances, such as when moving abnormal indivisible loads, but special provisions are in place to deal with these occasions, which can be found in the Road Vehicles (Authorisation of Special Types) (General) Order 2003.

(Video) Towing a trailer can be dangerous with the wrong weight distribution

A vehicle is overloaded if it exceeds the weight limits displayed on either the manufacturers’ or ministry plates. A vehicle could be overloaded on itsaxle(s), gross and train weight, witheach of thesebeing separate offences e.g.a 3 axle articulated vehicle exceeding the plated weights on the 1st axle, and 2nd axle and gross weight would make both the vehicle operator and driver liable to three separate offences.

It is important that vehicles are not overloaded, given that the effects are likely to be:

  • Road Safety-vehicles that are loaded beyond their design weight are likely to be less stable and will take longer to stop, particularly in an emergency
  • Road Wear-the structural road wear attributable to vehicles is normally assumed to be proportional to the fourth power of the axle weight;this means,for example,that a 10% increase in the weight imposed on a road by an axle is assumed to increase structural road wear by 46%, and a vehicle with 2 times the axle weight of another vehicle will cause 16 times the wear
  • Competition– overloading provides illegal operators with an unfair advantage over those operating within the legal limits

If a vehicle’s gross or axle weight limits are found to have been exceeded when weighed by either DVSA, the police or trading standards officers, the company and/or driver risk prosecution. In addition to this, an overloading conviction is one of the factors that could lead to a Traffic Commissioner taking disciplinary action against the operator’s licence.The fines for overloading are high.

In most cases of serious overloading offences, these would be dealt with in a magistrate’s court for both driver and operator and in the case of the operator, the operator would likely be summoned to a public inquiry (PI).

What happens if a trailer is overloaded? ›

An overloaded trailer can damage far more than the goods within it – it even puts your car at risk of a severe accident. The excessive weight in the back will press on the rear bumper, removing pressure from the front of the vehicle. By slightly raising the front wheels, your car's contact patch is minimised.

What happens when you exceed your vehicle's towing capacity? ›

Max towing capacity should not be taken lightly. Exceeding what your vehicle is designed to tow can strain your engine and transmission, accelerate brake wear, damage your tires and even warp your chassis. This could in turn trigger catastrophic failure while driving and could lead to property damage or serious injury.

How much can you overload a car trailer? ›

Try to keep about 60% of the load in the front half of your trailer. Don't overload the end of the trailer, or it could damage your trailer and cause other hazards. Try to keep your GVWR to about 80% of the allowed amount.

How much overloading is allowed? ›

"Explanation - For the purposes of this notification, the tolerance upto five percent in the gross vehicle weight and safe axle weight as specified above may be allowed for the purpose of compliance to sub-section (3) of section 113 of the Motor Vehicles Act, 1988(59 of 1988).”.

What are the consequences of overloading? ›

Exceeding the rated load for the circuit wiring causes the circuit breaker to trip, shutting off the power to the entire circuit. If there were no breaker in the circuit, an overload would cause the circuit wiring to overheat, which could melt the wire insulation and lead to a fire.

What happens when a vehicle is overloaded? ›

Heavier the vehicle, more the momentum and kinetic energy of the vehicle will be. This decreases the vehicle's ability to stop quickly and will cause a wear and tear on the brakes as well as on tires that could have lasting negative effects.

What does maximum towing capacity mean? ›

Your towing capacity is the maximum weight that your vehicle can pull safely. However, while this sounds simple there's a lot more that goes into determining your towing capacity than simply the number printed on your vehicle.

What are the two rules for overloading methods? ›

Remember these rules when overloading a method:
  • The overloaded and overloading methods must be in the same class (Note: this includes any methods inherited, even implicitly, from a superclass).
  • The method parameters must change: either the number or the type of parameters must be different in the two methods.

What happens if you overload a truck? ›

Consistently running overloaded on a truck will lead to maintenance issues. It will break down essential components more quickly and could lead to damage that might pose safety risks. There is also evidence that as weight increases on a truck there is also an increase in the potential for an accident.

What happens if a vehicle is loaded with very little weight? ›

Too little weight on the driving axles can cause poor traction. The drive wheels may spin easily. During bad weather, the truck may not be able to keep going. Weight that is loaded so there is a high center of gravity causes greater chance of rollover.

What does overloaded trucks mean? ›

Overloaded trucks

The first is overloading, which takes place when the truck is so heavy that it exceeds the weight limits set by the Federal Motor Carrier Safety Administration (FMCSA). The permissible weight varies depending on the truck.

What is GVWR mean on a trailer? ›

“GVWR” (Gross Vehicle Weight Rating); the GVWR refers to the maximum weight a vehicle is designed to carry including the net weight of the vehicle with accessories, plus the weight of passengers, fuels, and cargo. The GVWR is a safety standard used to prevent overloading.

What is the difference between towing and hauling capacity? ›

So, the towing capabilities of a truck means how much it can pull, for example on the trailer that is attached to the said truck. Whereas the hauling capability of a certain vehicle means how much you can put on it and be able to move. For example, you can load your truck bed and move the cargo that way.

Simply put, your Gross Vehicle Weight Rating (GVWR) is the maximum amount of weight that your trailer is rated to carry. This number INCLUDES the weight of the trailer itself and the cargo/equipment you plan to haul.

How do you calculate towing capacity and payload? ›

Summary. Your vehicle's maximum payload equals the GVWR, minus the curb weight. On the other hand, Towing capacity is equal to the GCVWR minus the curb weight. Thankfully, both numbers are easy to calculate so that you can travel safely and reliably.

What is mandatory if the gross trailer weight is 3 500 pounds or more? ›

Weight-carrying hitches can tow up to 3,500 pounds gross trailer weight. The biggest liability in the hitch's ability to tow more is its inability to distribute weight from side to side. If you wish to tow more than 3,500 pounds, you need a weight-distributing hitch.

What is the difference between towing capacity and trailer weight? ›

Trailer Weight vs Towing Capacity

Gross trailer weight is the total calculated weight of a trailer and its cargo. GTW isn't so much a rating as it is a measurement. Towing capacity, on the other hand, is the maximum allowable weight a vehicle can tow as determined by the manufacturer.

Can I tow a trailer with a higher GVWR than my truck? ›

Vehicle manufacturers provide a “tow rating” in their owner's manuals which provides the maximum weight the tow vehicle can tow when fully loaded. The GVWR of the trailer should never exceed the tow rating of the tow vehicle, even if the trailer is not loaded to its maximum capacity.

How do you weigh a tow vehicle and trailer? ›

Weigh your tow vehicle with the trailer attached and the weight distribution bars/ mechanism engaged. Each axle will need to be weighed individually. You will weigh the trailer axle(s) on one pad of the commercial scale, the rear axle of the tow vehicle on another, and the front axle on a third pad.

What is the difference between GVWR and payload? ›

A vehicle's GVWR is the maximum amount of weight the vehicle can weigh when fully loaded with occupants and cargo. A vehicle's payload rating is the amount of weight the vehicle can haul and is calculated by subtracting the vehicle's actual curb weight from its gross vehicle weight rating.

How do you know if your load is too heavy? ›

The heavier the load, the more difficult it is to slow down. If you spot a truck that is braking but taking a while to slow down, then the truck must be carrying too much weight. The truck's suspension springs are compressed. If a truck bounces when it's carrying a load, it means that it is within weight restrictions.

How do I know if my trailer is too heavy for my truck? ›

The short answer is that you want to make sure the weight of the trailer and its load doesn't exceed the gross vehicle weight rating of your truck, car, or SUV. In standard situations, if your vehicle's GVWR is 10,000 lbs and you only plan to haul 1,000 lbs of cargo, you're good to go. But that's not always the case.

What are the two types of overloading? ›

There are mainly two types of overloading, i.e. function overloading and operator overloading.

What are the 4 rules of operator overloading? ›

Some rules regaring operator overloading
  • Overloading an operator cannot change its precedence.
  • Overloading an operator cannot change its associativity.
  • Overloading an operator cannot change its "arity" (i.e. number of operands)
  • It is not possible to create new operators -- only new versions of existing ones.

Which of the following is an example of method overloading? ›

In Java, two or more methods may have the same name if they differ in parameters (different number of parameters, different types of parameters, or both). These methods are called overloaded methods and this feature is called method overloading. For example: void func() { ... }

What is the solution for overloading? ›

The immediate solution to an overload is simple: Shift some plug-in devices from the overloaded circuit to another general-purpose circuit. Then, flip the circuit breaker back on or replace the fuse and turn stuff back on.

What is overloading procedure? ›

Overloading a procedure means defining it in multiple versions, using the same name but different parameter lists. The purpose of overloading is to define several closely related versions of a procedure without having to differentiate them by name.

Which of the following is not allowed to be overloaded? ›

How do you calculate trailer load capacity? ›

Subtract the curb weight from the GVWR to find the payload capacity. For example, if you have a light-duty truck with a GVWR of 9,000 pounds and a curb weight of 6,000 pounds, the payload capacity will be 3,000 pounds: GVWR – curb weight = payload capacity. 9,000 pounds – 6,000 pounds = 3,000 pounds.

What is considered a heavy load trailer? ›

Heavy-duty models weigh up to 5,200 pounds. The capacity of a large enclosed utility trailer can vary based on how many axles it has, the construction of the frame and other factors. In general, the average cargo capacity is 4,400 pounds.

When loading a trailer, where should you put the weight? The simple rule to follow is to place 60% of the weight in front of the axle and 40% behind.

What is the difference between tongue weight and trailer weight? ›

Tongue weight is the amount of your trailer's weight that transfers to your tow vehicle through the trailer's tongue or gooseneck. Tongue weight can be measured on any certified scale. First, drive your tow vehicle onto the scale and measure its weight. Its weight needs to be less than the GVWR.

What is the difference between hitch weight and towing capacity? ›

If your truck has a manufacturer's tow rating of 12,000 lbs but the hitch being used has a 5,000 lb capacity, you'd be limited to the capacity of the hitch. Conversely, if you have a 12,000 lb rated hitch on a vehicle with a 5K tow rating, you'll be limited to a 5,000 lb capacity.

What does 500 lb tongue weight mean? ›

What does 500 lb. tongue weight mean? Usually, the tongue weight is just a representation of how much you are towing. For example, a 500-pound tongue weight would ideally mean you are hauling a 5,000-pound trailer.

Is towing hard on engine? ›

Towing causes additional strain on your vehicle, from the engine to your brakes. So, it will slowly wear on your engine over time, no matter your vehicle or trailer. However, some big things will lead to faster wear and more substantial damage.
