Setting up a variable message sign (VMS) usually means manoeuvring a trailer on site. SG has launched a palletised VMS unit that leaves the trailer behind. The VMS-P is mounted on a standard pallet and can be delivered and moved by forklift, Hiab or a specialised pallet-lifting trailer. This change reduces site setup time and lowers ongoing maintenance needs.
How the VMS-P works
The VMS-P eliminates the towable chassis traditionally used for VMS units. Instead, the sign sits on a standard pallet frame. SG’s SOSEC trailer lifts and deposits the pallet, allowing one vehicle to deliver and reposition multiple signs across a site or along a route. The sign carries a full-colour LED matrix display, showing amber, red, green, blue and white graphics through a non-glare, UV-resistant polycarbonate screen.
Without wheels, brakes, or a hitch, the unit has fewer mechanical parts requiring maintenance. GPS tracking and padlock covers reduce theft risk compared to trailer-mounted signs. Messages are updated remotely through Windows, Android or iOS apps, removing the need for site visits. Solar panels maintain power under recommended conditions, allowing indefinite operation.
Where it fits on UK roads
The standard ‘A size’ VMS-P is rated for speed zones up to 50mph, making it suited to urban and inner-city roadworks rather than high-speed strategic routes like motorways. The smaller footprint helps in areas where trailer parking is limited. Its flexibility is also applicable to temporary events or construction sites requiring clear diversion or lane closure messages.
The launch comes amid ongoing framework procurements such as National Highways’ Scheme Delivery Framework (SDF2), where traffic management equipment categories do not explicitly name variable message signage. SG expects contractors and authorities to clarify VMS sourcing as SDF2 and the Maintenance & Response 2 framework advance.
What it changes for contractors and authorities
Removing the trailer means fewer breakdowns and servicing delays. Fleet owners require fewer trucks dedicated to individual signs, cutting downtime and cost. The lower theft risk increases asset availability and reduces replacement costs.
SG describes this as raising the standard for urban roadworks signage, removing what it calls an unnecessary security and maintenance burden. The ability to manage messages remotely also allows rapid response to changing site conditions without physical attendance.
Availability and next steps
VMS-P units are available now for purchase or hire. SG will demonstrate the product at Highways UK, NEC, on 14–15 October. Full technical details can be found online at solargates.co.uk/solution/vms-signs/vms-p.
SG operates alongside related businesses MVIS and P&D Specialist Services within the Torquay Group, strengthening its position in roadside technology for UK contractors and local authorities.
