Unmatched Visibility for Drivers
5-Star Direct Vision Standard Rating


“The Volta Cab design is the highest performing cab design that has been tested under the TfL DVS method. The rating of the Volta Cab design is DVS TfL 5 star.”

Surpassing the competition
Our enhanced design ensures that the Volta Zero boasts exceptional visibility for the driver, far surpassing our competition. Our truck provides an unparalleled field of view that is at least 50% superior to any other truck, electric or otherwise. In truth, the Volta Zero is so far ahead of our rivals that the recent 5-star Direct Vision Standard (DVS) rating for best-in-class visibility seems understated.
“During the Mayor of London Sadiq Khan’s visit to our facility, we were proud it was suggested by architects of the DVS system that a new 10-star scale could be required – to properly illustrate just how far ahead our trucks really are in terms of visibility”

Visibility of vulnerable road users
This unprecedented degree of visual clarity means a much safer environment for other road users, especially cyclists and pedestrians, as they can now be more easily seen by drivers, reducing the potential for accidents.
Driving made easier
The innovative design of the Volta Zero is not just great news for other road users, it is also provides significant benefits for the drivers of our trucks. Greater visibility means driving is much easier and less stressful, while the lower seat position allows much more convenient access to the truck. The driver’s well-being is a key point in our pursuit of sustainable living.
Transforming perceptions
By creating safer trucks that are less stressful to drive, what was once considered a taxing, high-stress and hazardous job is transformed into a much more appealing career path, attracting a diverse pool of potential drivers.
Direct visibility: A deliberate design choice
The exceptional visibility and safety features of the Volta Zero weren’t a mere coincidence, but a deliberate design choice. We drew inspiration from Dr. Summerskill’s pioneering work on the Direct Vision Standard, integrating his findings into our cab design for optimal visibility and safety in urban environments – the natural habitat for the Volta Zero.
