5 minutes, 58 seconds Read

In an increasingly uncertain world, security is a paramount concern for governments, businesses, and individuals. Protecting critical infrastructure, public spaces, and private property from potential threats has never been more critical. Road blockers, often in the form of bollards, have become an essential component of security measures. This article will delve into the world of road blockers, explaining how they work and their role in enhancing security. We will also explore the relevance of LPS 1175, a crucial standard in the field of security, in relation to road blockers.

The Growing Importance of Security Measures

In an era characterized by evolving threats and vulnerabilities, security has become an ever-pressing concern. With the increase in terror attacks and the need to protect critical infrastructure, it is crucial to employ robust security measures. Road blockers have emerged as one of the fundamental tools in the arsenal of security professionals.

Road Blockers: An Overview

Road blockers, often referred to as security bollards, are physical barriers designed to prevent unauthorized access to a specific area. They are used in various settings, including airports, government facilities, commercial properties, and public spaces. Road blockers come in different forms and sizes, with various mechanisms for deployment. The fundamental purpose of these blockers is to enhance security by obstructing vehicular access.

Types of Road Blockers

  1. Fixed Bollards: Fixed bollards are static barriers that are permanently installed in a particular location. They are typically made of heavy-duty materials like concrete or steel and provide a high level of security.

  2. Retractable Bollards: Retractable bollards can be raised or lowered as needed. They are often used in areas where occasional access is required, such as driveways or entry points to secure facilities.

  3. Automatic Rising Arm Barriers: These are typically seen at parking facilities, and they use a rising arm mechanism to control vehicular access.

  4. Surface-Mounted Bollards: These bollards are installed on the surface, rather than being embedded in the ground, making them easier to install and relocate.

  5. Crash-Rated Bollards: These are specially designed to withstand the impact of a vehicle, making them ideal for high-security installations, such as airports or government buildings.

How Do Road Blockers Work?

The operation of road blockers depends on their type and intended use. However, they all share a common goal: to prevent or control vehicular access to a particular area. Let’s delve into the workings of some common road blocker types.

Working of Fixed Bollards

Fixed bollards are typically made of robust materials like steel or concrete, making them sturdy and resistant to impacts. They are permanently anchored to the ground, providing an unyielding barrier against unauthorized access. These bollards work by obstructing the path of a vehicle, preventing it from advancing.

Retractable Bollards

Retractable bollards, also known as automatic bollards, have a mechanism that allows them to be raised or lowered as needed. They are controlled electronically, and their operation can be initiated by security personnel or automated systems. When raised, they form an impenetrable barrier. Lowering them allows authorized vehicles to pass through.

Automatic Rising Arm Barriers

Automatic rising arm barriers use a horizontal arm that is raised to allow vehicles to pass. The arm is typically made of sturdy materials, ensuring that it can withstand attempted breaches. Access control systems manage the operation of these barriers, and they are commonly found in parking facilities, gated communities, and toll booths.

Surface-Mounted Bollards

Surface-mounted bollards are installed on the surface, making them easier to install and relocate. They are often used for temporary security measures or in areas where permanent fixtures are not practical. Their operation is similar to that of fixed bollards, but they can be moved when necessary.

Crash-Rated Bollards

Crash-rated bollards are designed to withstand the impact of a vehicle, even in high-speed collisions. They are tested and certified to specific crash test standards, such as the U.S. Department of State’s K-Rating and the British PAS 68 standard. These bollards work by absorbing and dissipating the kinetic energy of the vehicle, preventing it from penetrating the protected area.

The Role of LPS 1175 in Road Blocker Security

LPS 1175 is a widely recognized security standard that plays a vital role in ensuring the effectiveness of road blockers and other security measures. Developed by the Loss Prevention Certification Board (LPCB), LPS 1175 sets the benchmark for physical security in various applications.

Understanding LPS 1175

LPS 1175 provides a clear and rigorous classification system for security products and systems, including road blockers. The standard categorizes security measures into different levels, with Level 1 being the lowest and Level 8 being the highest. Each level corresponds to a specific level of threat and the ability of a security product to resist intrusion.

How LPS 1175 Impacts Road Blocker Security

When it comes to road blockers, LPS 1175 certification ensures that the product has undergone rigorous testing and meets specific security requirements. The standard covers a wide range of physical security products, including gates, barriers, and bollards. Road blockers are classified based on their ability to resist forced entry and withstand attacks from different tools and vehicles.


Road blockers that meet higher LPS 1175 levels provide enhanced security. These blockers have been tested to withstand determined and well-equipped attackers. By specifying LPS 1175-rated road blockers, security professionals can select the appropriate level of protection for their specific needs, ensuring that the chosen blocker can effectively deter unauthorized access.

Advantages of Road Blockers for Security

Road blockers offer several advantages that contribute to enhanced security. Understanding these benefits is crucial in making informed decisions about the implementation of road blockers in various security scenarios.

Physical Barrier

Road blockers create a physical barrier that is nearly impenetrable. This makes it challenging for vehicles to breach secured areas, thereby deterring potential threats.

Controlled Access

Road blockers allow for controlled access. Authorized vehicles can be granted permission to pass through, while unauthorized ones are blocked. This controlled access enhances security while ensuring smooth operations.

Visual Deterrent

The mere presence of road blockers can act as a visual deterrent to potential intruders. Knowing that access is restricted by these barriers can discourage unauthorized individuals from attempting to breach security.


Road blockers can be customized to suit the specific security requirements of an installation. This includes the choice of materials, level of impact resistance, and integration with access control systems.

Compatibility with Other Security Measures

Road blockers can be seamlessly integrated with other security measures, such as surveillance cameras, access control systems, and alarms. This comprehensive approach to security enhances overall protection.


Road blockers are designed with safety in mind. They are engineered to minimize the risk of injury to pedestrians and vehicle occupants in the event of a collision.

Minimal Maintenance

Once installed, road blockers require minimal maintenance. They are built to withstand harsh environmental conditions, ensuring long-term reliability.



Road blockers are essential security tools that effectively enhance safety and deter potential threats by creating robust physical barriers and allowing for controlled access. The selection of road blockers meeting relevant standards, such as LPS 1175, is crucial to ensure their effectiveness in safeguarding critical infrastructure, public spaces, and private property. As technology and security challenges evolve, road blocker supplier plays a pivotal role in providing adaptable and reliable solutions, making the world a safer place.
