The Short Answer
A commercial vehicle safety system is equipment or technology designed to help reduce the risks associated with operating vans, trucks, buses and other working vehicles.
Commercial vehicle safety technology can take many forms. Some systems improve the driver’s visibility or warn them about nearby road users and objects. Others monitor the vehicle or driver, intervene when a potential collision is detected, or record footage and data that can be reviewed following an incident.
Safety technology may be fitted by the vehicle manufacturer or added later as an aftermarket system, and several different technologies may operate alongside one another on the same vehicle.
There is no single safety system that is suitable for every commercial vehicle. The appropriate technology depends on the vehicle, how and where it is used, and the particular risks the operator is trying to address.
What Types Of Commercial Vehicle Safety Technology Are Available?
The term commercial vehicle safety system covers a broad range of technologies rather than one particular type of product.
These can include:
- Visibility cameras, which provide the driver with a view of areas that may otherwise be difficult or impossible to see
- Proximity and detection systems, which monitor defined areas around the vehicle and warn the driver when an object or vulnerable road user is detected
- AI camera systems, which use image processing to identify particular types of road user, object or other potential hazard
- Advanced Driver Assistance Systems (ADAS), which can use cameras, radar and other sensors to support functions such as collision warnings, automatic emergency braking and lane monitoring
- Driver monitoring systems, which can identify signs of fatigue, distraction or other behaviours that may affect safe driving
- Vehicle monitoring systems, which can monitor factors such as tyre pressure or other vehicle conditions that may affect safe operation
- Recording cameras and digital video recorders, which capture footage and, depending on the system, additional information such as vehicle location or trigger events
- Audible and visual warnings, which can alert the driver or people outside the vehicle to a particular risk
Some technologies are also designed around particular vehicle movements or areas of risk. Blind Spot Information Systems (BSIS), for example, monitor areas alongside a vehicle, whilst Moving Off Information Systems (MOIS) monitor the area immediately in front when the vehicle is preparing to move away.
These technologies may operate independently or form part of a wider vehicle safety system.
What Risks Can A Commercial Vehicle Safety System Address?
Commercial vehicles can present very different risks depending on their size, design and the work they perform.
A large truck may have areas around the vehicle that cannot be seen directly by the driver. A refuse vehicle may operate regularly around pedestrians and cyclists. A construction vehicle may work in confined areas alongside people and other machinery. Agricultural vehicles may use different trailers and implements throughout the working day.
Safety technology can help address risks such as:
- restricted visibility around the vehicle
- reversing collisions
- vulnerable road users alongside or in front of the vehicle
- objects within areas that are difficult for the driver to see
- driver fatigue or distraction
- vehicle conditions that could affect safe operation
- lack of evidence following an incident
Different risks require different approaches.
A camera intended to improve visibility performs a different role from a system designed to detect cyclists, monitor tyre pressure or apply the brakes automatically.
The important point is that the technology should be selected for the risk rather than equipment being fitted simply because it is available.
How Do Cameras Improve Commercial Vehicle Safety?
Cameras can give the driver views that conventional mirrors or direct vision cannot always provide.
A rear camera, for example, can help a driver see immediately behind a vehicle whilst reversing. Side cameras can improve visibility alongside a vehicle, whilst front and corner cameras can provide additional visibility into areas obscured by the vehicle’s bodywork.
The usefulness of a camera depends heavily on where it is positioned and what the driver actually needs to see. A camera that provides an excellent view on one vehicle may be poorly suited to another because of differences in body shape, dimensions or working environment.
Camera position and field of view should therefore be considered as part of the overall system design rather than simply choosing a camera and finding somewhere to mount it.
How Do Detection And Warning Systems Help?
Where cameras provide information for the driver to interpret, detection systems can actively monitor defined areas around the vehicle.
Different technologies are available for different applications.
Some systems detect any object entering a detection zone, whilst others are designed to identify particular hazards such as pedestrians or cyclists. Systems such as BSIS and MOIS are designed to monitor particular areas around a vehicle where vulnerable road users may be at risk.
When a relevant hazard is detected, the system may provide an audible or visual warning to the driver. External warnings can also be used in some applications to alert people around the vehicle.
The objective is not simply to generate more warnings. Alerts need to be relevant, timely and understandable if they are going to help the driver rather than become another source of distraction.
What Is The Role Of Recording Technology?
Not every commercial vehicle safety system is intended to address an immediate risk.
Recording cameras and digital video recorders can provide evidence of what happened before, during and after an incident. This can help fleets investigate collisions, respond to insurance claims and understand recurring operational risks.
More advanced recording systems may also capture information such as GPS location, vehicle speed or inputs from other equipment.
Recording technology therefore performs a different role from a visibility camera or proximity sensor, although the technologies can form part of the same overall system.
What Is The Difference Between Factory-Fitted And Aftermarket Safety Systems?
Some vehicle safety technologies are incorporated into the vehicle during manufacture.
These can include systems such as automatic emergency braking, lane assistance, driver monitoring and tyre pressure monitoring, depending on the vehicle.
Other safety technology can be installed after the vehicle has been manufactured. Aftermarket systems are commonly used where an operator needs additional cameras, sensors, recording equipment or other technology to address risks associated with a particular application.
Factory-fitted and aftermarket systems are not necessarily alternatives to one another. Both may be present on the same vehicle and perform different safety functions.
What matters is understanding what existing equipment already does before deciding whether additional technology is required.
Can Different Safety Technologies Work Together?
Yes, different safety technologies can operate together on the same commercial vehicle, and some applications may benefit from combining several systems.
A vehicle might use cameras to improve driver visibility, sensors to provide active warnings and a recording system to retain footage from around the vehicle. These may operate alongside safety technology originally fitted by the vehicle manufacturer.
How those systems interact is important.
Drivers should not have to manage unnecessary monitors, conflicting warnings or complicated controls simply because several technologies have been installed.
Compatibility also matters. Cameras, monitors, sensors, recorders and control equipment may use different connections, formats and trigger arrangements, so equipment should not automatically be assumed to work together simply because it can be physically connected.
The complete vehicle and its safety technologies should therefore be considered together rather than viewing every individual component in isolation.
Does Every Commercial Vehicle Need The Same Safety System?
No, even two vehicles that appear similar may require different equipment if they perform different jobs.
A rigid truck making urban deliveries faces different risks from a tractor and trailer operating predominantly on motorways. A refuse vehicle working around pedestrians has different requirements from an agricultural machine working in a field.
Vehicle dimensions, bodywork, operating environment, manoeuvres, driver requirements and the people or objects likely to be around the vehicle can all influence what technology is appropriate.
Regulatory, contractual or site requirements may also specify particular equipment, but compliance should not replace an assessment of the vehicle’s actual operational risks.
The objective should not be to fit as much technology as possible. It should be to identify the risks that need addressing and determine which safety measures are appropriate.
Can Commercial Vehicle Safety Systems Prevent Accidents?
Commercial vehicle safety technology can improve visibility, provide warnings, monitor risks and provide evidence, but it cannot guarantee that an incident will never occur.
Its effectiveness depends on factors including the suitability of the technology, correct installation, maintenance, driver understanding and the conditions in which the vehicle operates.
Some technologies can actively intervene in particular circumstances, such as automatic emergency braking, whilst others provide information or warnings that help the driver respond to a developing situation.
Safety systems should therefore support good driving, training and operating procedures rather than being treated as a replacement for them.
Final Thoughts
A commercial vehicle safety system is not necessarily a single product or a fixed package of equipment.
The term covers a wide range of technologies, from factory-fitted driver assistance and vehicle monitoring systems to aftermarket cameras, sensors, warning systems and recording equipment.
Each performs a different role.
Cameras can improve visibility. Detection systems can warn of nearby hazards. Driver and vehicle monitoring systems can identify other potential risks. Recording systems can provide valuable evidence and operational information.
The appropriate combination depends on the vehicle, the work it performs and the problem the fleet is trying to solve.
At SCC, we design and manufacture vehicle safety technology for a wide range of commercial vehicles and applications. Our approach is to understand the vehicle and its operation first, then determine which technology is appropriate for the risks involved.
Sometimes that requires several technologies working together. Sometimes a single well-chosen product is all that is needed.
