Case Study: Waste Management Fleet Achieves Full DVSA Compliance and Cuts Incidents by 35%
Illustrative case study representing typical results achievable by waste management and refuse collection operators using AutoKontrol speed limiter technology.
Overview
| Detail | Information |
|---|---|
| Sector | Waste management and refuse collection |
| Fleet size | 95 vehicles (RCVs, skip loaders, roll-on/off, hook loaders) |
| Vehicles | 7.5t to 32t GVW, mixed manufacturers |
| Deployment period | 8 months |
| Key result | Full DVSA compliance achieved; zero prohibition notices |
| Speed-related incident reduction | 35% year-on-year |
| ROI achieved | Month 9 |
A waste management company operating 95 specialist vehicles across three local authority contracts was facing a compliance crisis. A DVSA encounter at a roadside check had resulted in two immediate prohibition notices for speed limiter defects, followed by an investigation that identified systemic non-compliance across the fleet. The company’s operator’s licence — and therefore its ability to fulfil the local authority contracts that represented 80% of revenue — was directly at risk.
AutoKontrol was engaged to replace the fleet’s ageing and poorly maintained speed limiters with System 80 Drive-By-Wire units, integrated with TrackSpeed for ongoing compliance monitoring. Within eight months, every vehicle was fully compliant, the DVSA investigation was resolved without further action, and speed-related incidents had fallen by 35%.
The Challenge
DVSA Prohibition Notices
The two prohibition notices were issued during a routine roadside check on a Tuesday morning. One vehicle’s speed limiter was found to be non-functional — the unit had failed but the fault had not been detected or reported. The second vehicle’s speed limiter was set to 62 mph rather than the required 56 mph, indicating either incorrect calibration or tampering.
Under DVSA enforcement procedures, the prohibition notices triggered a broader investigation. DVSA requested speed limiter calibration records for the entire fleet. The company’s records were incomplete: 22 vehicles had no current calibration certificate, 14 had certificates that were more than two years old, and 8 had certificates from a supplier that was no longer trading.
The Traffic Commissioner’s office was notified, and the operator was informed that a public inquiry could be called if the deficiencies were not addressed within a specified timeframe.
Operational Complexity of Waste Vehicles
Waste management vehicles present specific challenges for speed limiter maintenance. Refuse collection vehicles (RCVs) operate in demanding conditions — frequent stop-start cycles, hydraulic systems that stress electrical components, and exposure to vibration and contamination. Speed limiters fitted to these vehicles are subject to higher failure rates than those on long-haul HGVs if not specified appropriately.
The fleet’s existing speed limiters were a mix of three different makes and models, fitted at different times by different installers. There was no standardised specification, no centralised maintenance schedule, and no remote monitoring capability. Identifying which vehicles were compliant at any given time required individual physical inspection.
Local Authority Contract Risk
All three local authority contracts included clauses requiring the operator to maintain a valid operator’s licence and demonstrate compliance with all relevant transport regulations. A public inquiry, let alone licence revocation, would trigger contract termination provisions. The combined annual value of the three contracts was £6.8M.
The Solution
System 80 Fleet Standardisation
AutoKontrol recommended replacing all existing speed limiters with the System 80 Drive-By-Wire unit, standardised across the entire fleet regardless of vehicle manufacturer or age. System 80 was selected specifically for its proven durability in demanding operational environments — the sealed, vibration-resistant design is suited to the stop-start and hydraulic-intensive duty cycle of waste vehicles.
Standardisation eliminated the maintenance complexity of managing three different speed limiter types. Every vehicle now runs the same hardware, the same calibration process, and the same diagnostic protocols.
TrackSpeed Integration for Continuous Compliance
TrackSpeed was deployed alongside System 80 to provide continuous remote monitoring of speed limiter function. The system reports speed limiter status in real time, generates automatic alerts if a fault is detected, and maintains a digital calibration and compliance record for every vehicle.
This moved the operator from a position where speed limiter faults could go undetected for weeks or months to one where any fault generates an immediate alert to the fleet engineering team.
SGH Connect Installation Programme
SGH Connect managed the installation across the operator’s two depot locations. Given the DVSA timeline pressure, the programme was accelerated: vehicles were scheduled in batches of 12-15 per week, with installations completed overnight to avoid disrupting daytime collection rounds.
Phase 1 (Months 1-2): The 22 vehicles with no current calibration and the 8 with untraceable records — addressing the highest-risk vehicles first.
Phase 2 (Months 3-5): Remaining HGVs and specialist vehicles, prioritised by next DVSA encounter risk (vehicles operating on routes with known DVSA check points received priority).
Phase 3 (Months 6-8): Final vehicles, system integration checks, and establishment of the ongoing maintenance and monitoring programme.
DVSA Engagement
AutoKontrol’s compliance team worked directly with the operator to prepare a remedial action plan for submission to DVSA and the Traffic Commissioner’s office. The plan documented the scope of the System 80 deployment, the phased timeline, and the TrackSpeed monitoring capability that would prevent recurrence.
The plan was accepted by the Traffic Commissioner’s office, and the public inquiry was not called. The operator was placed on a monitoring period with a compliance audit scheduled for six months after the completion of Phase 3.

What the Fleet Manager Said
“The DVSA notices were a wake-up call we should not have needed. We had been managing speed limiters the same way for ten years — fit and forget. The problem is that ‘forget’ eventually means ‘fail.’ System 80 and TrackSpeed have given us a compliance system we can actually manage. The Traffic Commissioner outcome could have ended this business. Instead, we came out with a Green OCRS rating and a fleet we can be genuinely confident in.”

Key Takeaways
- Speed limiter non-compliance in waste fleets is often systemic rather than isolated — the operational environment accelerates degradation
- DVSA enforcement can escalate rapidly from a single roadside check to a public inquiry — the timeline for remediation is shorter than most operators assume
- Standardising on a single speed limiter platform (System 80) dramatically simplifies fleet-wide compliance management
- Remote monitoring through TrackSpeed eliminates the “fit and forget” failure mode that leads to undetected faults
- A structured remedial action plan, submitted proactively, can prevent a Traffic Commissioner public inquiry
- The financial return extends well beyond compliance — fuel, insurance, and incident cost savings compound the case
