The question of what is the correct name for a specialized device that forcibly stops a vehicle by puncturing tires often arises in the context of discussing safety or studying road technology. In everyday life you can hear various variations: “hedgehog”, “spike tape” or simply “barrier”. However, the professional community and regulatory documents use more strict terminology, which reflects the complexity and purpose of this mechanism.
The main and most accurate technical name of this device is barrier complex or forced vehicle stop device (UPOT). These are the terms that appear in official documentation, technical specifications and laws governing the activities of law enforcement agencies. It is important to understand that this is not just a piece of metal with nails, but an engineering solution that requires accurate calculation and correct application.
There are many modifications of such systems, from simple mechanical structures to high-tech remote-controlled complexes. The differences lie in the speed of deployment, the number of lanes covered, and the activation method. In this article we will examine in detail what types of these devices there are, how they work and why their use is strictly regulated.
Official names and classification of devices
When it comes to professional terminology, the abbreviation comes to the fore UPOT, which stands for “Forced Transport Stopping Device”. This is a collective term covering a wide range of equipment used by intelligence agencies to block the movement of violators' vehicles. Depending on the design, such devices may have different names, but the essence of their work remains the same - mechanical damage to the wheels to stop the vehicle.
The name often appears in technical documentation barrier complex. It emphasizes that the device is part of a larger perimeter or checkpoint security system. Such complexes may include not only the spiked tape itself, but also alarm systems, video surveillance and remote control. This allows the operator to monitor the situation from a distance and make decisions about activation.
The term is worth mentioning separately shark teeth (shark teeth), which is sometimes used as a slang name in certain circles, although it has taken less root in the Russian-speaking segment. The more common division is by type of drive: mechanical, pneumatic and electric. Each type has its own advantages depending on the operating conditions and the required reaction speed.
Why so many names?
Terminological confusion arises due to the fact that the devices are developed by different manufacturers and departments. The military, police and private security agencies use their own internal designations, which over time penetrate into the public consciousness.
The key point is that any such device must have a passport and a certificate of conformity. The use of homemade analogues, even if they are called “spike tapes”, is illegal and can entail serious liability, since such designs are considered weapons or special equipment.
Design features and principle of operation
The operation of any forced stop device is based on a simple but effective physical principle. The tape or strip laid across the movement contains a number of sharp elements - spikes. In a quiet state, these elements are hidden inside the body or lie flat, without interfering with the movement of traffic. When activated, the mechanism pushes the spikes upward and they puncture the car tire, causing a rapid loss of pressure.
Modern barrier complexes often equipped with an anti-grab system. This means that after a tire puncture, the studs do not immediately retract, but remain in the raised position until a special signal is received from the operator. This is necessary to prevent a situation where the offender, realizing that he is being stopped, tries to back up and escape from the blocking zone.
The main feature of modern UPOTs is the ability to be reused and quickly reloaded without the operator leaving cover.
The materials used in production must withstand enormous loads. The body is made of high-strength steel, capable of withstanding the passage of a multi-ton truck or bus. The spikes are made of hardened steel or special alloys that do not become dull after the first use and are capable of punching even reinforced or bulletproof tires.
The process can be controlled in various ways. In stationary versions, the checkpoint uses a wired remote control or a button integrated into the security post. Mobile versions that police officers place on the road during pursuits may have a wireless control panel operating on secure frequencies to prevent attackers from intercepting the signal.
Types of barrier devices: from manual to automatic
The security systems market offers various modifications of devices for stopping vehicles. The choice of a specific type depends on the tasks facing the security service or law enforcement agency. The main division occurs according to the method of installation and control.
The first type is stationary complexes. They are installed directly into the road surface at the entrances to important facilities: military bases, nuclear power plants, closed administrative territories. Such devices are hidden under asphalt or paving stones and are not visible in normal mode. They are activated upon command from the security post. They are highly reliable and able to withstand constant traffic flow.
Second type - mobile (portable) devices. They are the ones most often shown in the news when dangerous criminals are apprehended. These are compact blocks that can be quickly deployed on the road. They can be mechanical (folded out manually) or pneumatic (folded out when gas is supplied from a cylinder). Their mobility allows them to be used in any place where there is a need to block traffic.
Third type - automated systems. This is the pinnacle of evolution in this area. Such complexes can independently recognize vehicle license plates, check them against “wanted” databases, and automatically activate upon approach. Although the level of automation is high, the final decision on the use of force usually rests with the human operator to avoid system errors.
Legal aspects of the use of special equipment
Using a spike strip to stop a car is not just a technical procedure, but a legally significant action. In the Russian Federation and many other countries, the use of such devices is strictly regulated by law. Only law enforcement officers (police, FSB, Russian Guard) have the right to use them when performing certain official tasks.
Individuals and security companies that do not have the appropriate licenses and approvals are prohibited from using devices classified as special equipment. The installation of homemade “hedgehogs” or purchased analogues on the access roads to a private house or dacha can be regarded as creating a danger to the life and health of citizens, as well as illegal possession of weapons.
If you are a representative of a private security company, be sure to check the availability of the device in the register of certified equipment approved for use by private security in your region.
There is a clear application procedure. The employee is obliged to warn about the use of special equipment (if the situation allows it), ensure the safety of others and minimize the risk of an accident involving third parties. After application, a report is drawn up indicating the reason for the stop, the type of device used and the results of its use. Any abuse of authority entails disciplinary and criminal liability.
It is important to note that damage to a vehicle as a result of the lawful use of special equipment is not subject to compensation from the state or department. However, if it is proven that the device was used unreasonably or in violation of the instructions (for example, at high speed in heavy traffic), responsibility falls on the user and his management.
Specifications and comparison of models
When choosing or studying various models of forced transport stop devices, experts pay attention to a number of key parameters. They determine the efficiency of the complex in real conditions. Below is a table comparing the main characteristics of popular device types.
Up to 10 tons
| Parameter | Mechanical "Hedgehog" | Pneumatic complex | Stationary UPOT |
|---|---|---|---|
| Deployment time | 5-10 seconds (manual) | 1-2 seconds | Instantly (from hidden state) |
| Number of lanes | 1 strip | 1-3 stripes | Up to 4 or more stripes |
| Spikes type | Removable/Fixed | Rotary blades | Retractable peaks |
| Load resistance | Up to 25 tons | Up to 60 tons and above | |
| Maintenance cost | Low | Average | High |
As can be seen from the table, pneumatic complexes are the golden mean between mobility and reaction speed. They are widely used by the patrol service. Stationary options, despite their high cost, are indispensable for protecting critical infrastructure facilities, where the risk of ramming is greatest.
Special attention should be paid to the resource of the studs. Modern models use replaceable tip blocks. After several successful applications (usually 10-15 punctures), the block requires replacement or sharpening, since a dull spike may not penetrate modern reinforced rubber, but only damage it, which will not lead to a quick stop of the car.
Safety and risks during use
Although effective, using spiked tape does carry some risks. The main danger is the possible loss of control of the car by the driver when the tires puncture. If this occurs at high speed, the vehicle may skid, posing a threat to pedestrians, other road users and the personnel conducting the operation themselves.
☑️ Risk factors when using UPOT
There is also a risk of damage to vital components of the vehicle. Although modern studs are designed to puncture a tire, damage to brake hoses, fuel lines, or suspension components can occur if the impact angle is poor or a faulty/homemade device is used. This may result in fire or complete loss of controllability.
⚠️ Warning: It is strictly prohibited to use forced stopping devices on motorcycles, open-top vehicles, or in conditions where stopping could lead to a disaster (for example, on a bridge or in a tunnel).
Employees using these products undergo special training. They learn to calculate the distance, choose the moment and place to install the barrier. Psychological preparation is also an important aspect, since the decision must be made in a split second.
To minimize risks, civilian vehicles are often equipped with reinforced tire sidewalls (RunFlat), which allow you to travel some distance after a puncture while maintaining controllability.
Frequently asked questions about traffic stop devices
Can I buy spiked tape for personal use?
It is not possible for a private individual to officially purchase a certified forced vehicle stop device (UPST). These products are specially registered and are sold only to legal entities that have the appropriate licenses (Ministry of Internal Affairs, FSB, private security company with special conditions). Purchasing analogues through online platforms may be regarded as purchasing products structurally similar to weapons, which is illegal.
What happens if you run over spikes at high speed?
When hitting barrier complex At high speed, the tire instantly punctures and the pressure goes out. The car suddenly loses stability. If the cleats are anti-grip, they can damage the disc. The main danger is loss of control over the trajectory, which often leads to a trip to the side of the road or a collision. In this case, the speed of the car does not drop instantly, but it is impossible to continue driving on flat tires.
What do people call spikes on the road?
The term “hedgehogs” or “spike tape” is most often used among people and in the media. You can also hear the names “comb” or “barrier”. However, in protocols and official reports it is necessary to use the full wording: “special means for stopping traffic” or the specific name of the model (for example, “UPOT-M”).
Is it possible to damage the suspension with such devices?
Certified devices are designed to minimize damage other than a flat tire. However, with repeated collisions or the use of faulty/handicraft products, the risk of damage to suspension elements, brake pipes and even the engine crankcase increases many times over. That is why the use of such means is permitted only in exceptional cases.
Are cars protected from such tapes?
Specialized vehicles (collection, transportation of valuables) can be equipped with reinforced wheels with internal reinforcement or tire inflation systems that allow you to continue driving even with multiple punctures. Ordinary civilian cars do not have such protection. There are also systems for detecting such devices, but they have not yet become widespread.
