01 / BLIND ZONE
No clear stopping reference
The pallet blocks the driver's direct view of the exit, increasing the chance of a rear-edge over-run.

Stop before the risk
Stop Line is a progressive, two-stage loading safety system being developed to reduce rear-threshold over-runs, injuries and damage to goods and equipment. Full-width amber and red markers guide drivers moving pallets and roll cages towards the rear of a vehicle—even when the load hides the edge.

03 / INTERVENTION
Visible Lines
Clear Boundaries
Amber signals the final approach. Red marks the stopping boundary, with both lines still visible at the pallet's sides.
The Stop Line system
As the driver pushes a pallet towards the tail-lift, the load crosses the amber line first. This signals entry into the final approach zone. The driver then stops the pallet before the red exit threshold.
Visible around the pallet. Because each line runs across the full vehicle width, it remains visible on either side of a standard UK pallet. The driver can look around the load and use those side markers instead of guessing the hidden distance to the rear edge.
01
Amber: slow the load
Crossing amber signals entry into the final approach zone. Reduce speed and prepare to stop.
02
Red: stop the load
Stop the pallet or roll cage before red. This is the final boundary before the tail-lift.

From Cab Visibility to Rear Safety
TfL-funded research found that safer vehicle design begins by making critical hazards directly visible. Stop Line applies that principle to rear loading: when a pallet or roll cage obscures the exit edge, full-width floor markers restore a clear approach and stopping reference.
TfL-FUNDED RESEARCHLOUGHBOROUGH DESIGN SCHOOL · 2015
Understanding direct and indirect driver vision in heavy goods vehiclesUsing collision-derived pedestrian and cyclist scenarios, the researchers compared how cab geometry, window design and driver position changed the size of direct-vision blind spots.
19HGV designs were digitally modelled across construction, distribution, long-haul and low-entry configurations.
STOP LINE RELEVANCE Vehicle layouts differ, so the rear boundary and amber approach position should be confirmed for each body and loading method.
TfL/LDS report · Executive Summary, p.4ALLEvery standard configuration assessed had a direct-vision blind spot capable of hiding a vulnerable road user.
STOP LINE RELEVANCE When a critical reference is hidden by physical geometry, the risk should be addressed through design as well as operator training.

DIRECT VISUAL CUE
The load can hide the exit edge
Full-width floor cues remain visible beside a pallet or roll cage, replacing a hidden edge with a progressive stopping decision.
AMBER · PREPARERED · STOP
Design determines what can be seen
The report linked blind-spot size to cab height, window-aperture design and the driver's position. Low-entry cabs demonstrated substantial direct-vision benefits over standard layouts.
Visibility must work under pressure
The researchers questioned whether small, distorted fragments of a road user can always be recognised across six mirrors in high-workload situations, and concluded that direct vision should be prioritised in vehicle design.
The rear has its own visibility gap
Inside the body, a pallet or roll cage can hide the rear edge from the person moving it. Training cannot restore a reference that has physically disappeared behind the load.
Put the decision into the floor
Stop Line proposes a direct, full-width cue that remains visible at the load's sides: amber signals the final approach and red defines the rear stopping boundary.
The Research Bridge. Rear-threshold design deserves the same disciplined attention: trials must assess operator safety, exposure to people nearby, and damage or disruption to the operation.
Evidence boundary. The TfL-funded report studied cab visibility around HGVs; it did not evaluate rear loading, Stop Line or economic outcomes. The rear-threshold connection above is Stop Line's design inference and proposed trial case—not a TfL finding, requirement or endorsement.

Specify the made-to-measure five-bar aluminium safety floor, then select the amber ribbed, red chequered or original bespoke EPDM insert route required for the application.

EPDM Inserts
A replaceable insert platform for safety visibility and vehicle-specific performance. Choose the amber approach insert, red stopping insert or commission an original made-to-order EPDM specification matched to the installed Stop Line channel.
CONFIGURE & CARE
One engineered profile, three commercial routes. Amber approach, red stop and a fully original bespoke specification—available for new Stop Line floors and matched replacement programmes, subject to final manufacturing validation. During routine cleaning or insert servicing, the EPDM and its seating area must be wiped clean and dry to limit trapped moisture, residue, mould and mildew.

VEHICLE-SPECIFIC SAFETY SYSTEMStop Line®
Stop Line® builds two unmistakable full-width decisions into a made-to-measure five-bar aluminium floor. Amber marks the final approach; red defines the rear stopping boundary. The reference build uses a 7 mm nominal aluminium floor with replaceable EPDM inserts approximately 2 mm deep and 50–60 mm wide, seated flush in machined channels. Routine operator care keeps each insert and its seating area clean, dry and ready for inspection.

- Clear decision pointsAmber identifies the final approach zone; red establishes the rear stopping boundary.
- Flush, tactile surfaceThe EPDM inserts sit within machined channels to avoid a raised trip edge.
- Serviceable by designWorn inserts can be replaced without replacing the complete aluminium floor.
- Routine operator careThe EPDM and its seating area must be wiped clean and dry after moisture, spillages or wash-down.

Built From the Cab. Engineered for the Fleet.
Stop Line comes from more than 15 years of professional HGV driving and first-hand understanding of how a small loading error can become a costly, dangerous incident in seconds.
The idea is deliberately simple: give the person moving the load a better visual decision point, then engineer that intervention to withstand the reality of commercial fleet work.
