In an effort to improve the safety of vulnerable road users such as pedestrians and cyclists, the London Mayor’s office has introduced the Lorry Direct Vision Standard (DVS). This standard requires all heavy goods vehicles (HGVs) over 12 tonnes to meet specific requirements for the driver’s field of vision from the cab of the vehicle. The goal of the DVS is to reduce the number of accidents involving HGVs and vulnerable road users, as collisions with these vehicles can often result in serious injuries or fatalities.
The DVS works by assigning a star rating to HGVs based on how much the driver can see directly through the cab windows without the need for additional mirrors or camera systems. The star rating is determined by a set of predefined criteria, with zero stars representing the lowest level of direct vision and five stars representing the highest level. HGVs that do not meet the minimum requirement of one star are prohibited from driving in Greater London unless they have undergone additional safety measures, such as installing cameras or sensors to improve visibility.
One of the key features of the DVS is the requirement for HGVs to have a panoramic window in the passenger side door, which allows the driver to have a better view of the area immediately next to the vehicle. This is particularly important when making left turns, as many accidents involving cyclists occur when HGVs fail to see them in their blind spots. By providing a clear view of the road, the panoramic window helps drivers make more informed decisions and reduces the risk of collisions.
In addition to the panoramic window, HGVs must also have side guards and close-proximity sensors to help prevent accidents with cyclists and pedestrians. Side guards are designed to prevent vulnerable road users from being dragged under the wheels of a vehicle in the event of a collision, while sensors alert the driver to the presence of objects or individuals in close proximity to the vehicle. These safety features work in conjunction with the direct vision requirements to create a safer environment for everyone on the road.
The implementation of the DVS has been met with mixed reactions from the transportation industry. While some companies have welcomed the standard as a step towards improving road safety, others have raised concerns about the cost of retrofitting their existing fleets to comply with the new regulations. Retrofitting a vehicle to meet the DVS requirements can be a costly endeavor, with estimates ranging from a few hundred to several thousand pounds per vehicle depending on the make and model.
Despite these challenges, the benefits of the DVS far outweigh the costs. By improving the visibility of HGV drivers and reducing blind spots, the standard helps to prevent accidents and save lives on the road. According to Transport for London, HGVs were involved in 63% of cyclist fatalities and 25% of pedestrian fatalities in Greater London between 2014 and 2018. By mandating the use of direct vision technology, the DVS aims to reduce these statistics and create a safer environment for all road users.
In addition to the DVS, the London Mayor’s office has also introduced the Direct Vision Permit, which is required for all HGVs driving in Greater London. To obtain a permit, vehicle operators must demonstrate that their HGVs meet the minimum requirements for direct vision, side guards, and close-proximity sensors. Failure to obtain a permit can result in fines and penalties, making it essential for companies to ensure that their vehicles are compliant with the DVS.
In conclusion, the Lorry Direct Vision Standard is a vital step towards improving road safety and protecting vulnerable road users. By mandating the use of direct vision technology and additional safety features, the DVS helps to reduce the risk of accidents involving HGVs and cyclists or pedestrians. While there may be initial challenges in retrofitting existing fleets to comply with the standard, the long-term benefits of improved road safety far outweigh the costs. As the DVS continues to be implemented in cities around the world, we can expect to see a significant reduction in accidents and fatalities on our roads.
