Case Study: Motorhome Rental Company Reduces Accidents by 45% with Voluntary Speed Limiters
Illustrative case study representing typical results achievable by motorhome and leisure vehicle rental operators using AutoKontrol speed limiter technology.
Overview
| Detail | Information |
|---|---|
| Sector | Motorhome and campervan rental |
| Fleet size | 120 motorhomes and campervans |
| Vehicles | Mix of coach-built motorhomes (3.5t-5.0t) and panel van conversions |
| Deployment period | 5 months (off-season installation) |
| Accident reduction | 45% year-on-year |
| Annual insurance saving | £62,000 |
| ROI achieved | Month 10 |
A motorhome rental company operating a fleet of 120 vehicles across four UK collection depots faced a problem unique to the leisure vehicle rental sector: its customers were inexperienced drivers operating large, unfamiliar vehicles at inappropriate speeds. The result was an accident rate three times higher than the company’s insurer considered acceptable, an insurance premium that had doubled in two years, and a growing concern about the company’s legal exposure under duty of care legislation.
The company engaged AutoKontrol to deploy System 80 speed limiters across the entire rental fleet — a voluntary decision, as motorhomes under 3.5 tonnes are not legally required to have speed limiters. The results were striking: a 45% reduction in accidents, a £62,000 annual insurance saving, and a significant strengthening of the company’s duty of care position.
The Challenge
Inexperienced Drivers in Large Vehicles
The fundamental challenge for any motorhome rental operator is that customers arrive with a standard car licence and leave with a vehicle that may be 7 metres long, 3 metres high, and weigh 3.5 tonnes or more. Most have never driven anything larger than a family car. They receive a 30-minute vehicle familiarisation briefing, then drive onto the motorway.
This company’s telematics data told a concerning story. Analysis of 2,400 rental journeys over 12 months showed that 38% of customers exceeded 70 mph on motorways, 22% exceeded 60 mph on single carriageways, and 11% triggered harsh braking events within urban areas at speeds above 35 mph. For a vehicle with a higher centre of gravity and longer stopping distances than a car, these speeds represented a genuine safety risk.
Escalating Insurance Costs
The fleet had recorded 31 at-fault claims in the preceding 12 months. The insurer’s analysis categorised 18 of these as speed-related — either direct (vehicle travelling too fast for conditions) or contributory (excessive speed reducing available stopping distance or reaction time). The remaining claims were manoeuvring incidents, which while not speed-related, contributed to an overall loss ratio that had reached 110%.
The premium had increased from £148,000 to £296,000 over two renewal cycles. The insurer made clear that a further renewal without demonstrable risk mitigation was unlikely.
Duty of Care Liability
The company’s legal advisers had raised concerns about the business’s exposure under the Corporate Manslaughter and Corporate Homicide Act 2007 and the Health and Safety at Work Act 1974. While rental customers are not employees, the duty of care principles extend to anyone affected by the company’s operations — including the customers themselves and other road users.
The legal opinion was that providing a large, unfamiliar vehicle to an inexperienced driver without reasonable speed management measures could constitute a failure to take “reasonably practicable” steps to manage a foreseeable risk. The company needed to demonstrate that it had done more than hand over the keys.
The Solution
Voluntary System 80 Deployment
AutoKontrol recommended the System 80 Drive-By-Wire speed limiter configured with speed profiles appropriate to each vehicle type:
- Coach-built motorhomes (3.5t+): 65 mph maximum. Although the legal motorway limit for these vehicles is 70 mph, the company and AutoKontrol agreed that a lower threshold was appropriate given the vehicle characteristics and driver inexperience. At 65 mph, the safety margin for braking distance and crosswind stability improves measurably.
- Panel van conversions (<3.5t): 70 mph maximum on motorways, consistent with the legal limit.
- All vehicles: 30 mph limit activated automatically in GeoKontrol zones around the four depot sites, where pedestrian customers and staff are present.
The decision to limit coach-built motorhomes below the legal limit was a key element of the duty of care strategy. It demonstrated that the company was not simply meeting the minimum legal requirement but was actively managing risk based on the specific characteristics of its vehicles and customers.
Off-Season Installation Programme
SGH Connect completed the installation during the winter off-season (November to March), when fleet utilisation was at its lowest. This timing meant that no rental revenue was lost during the programme. Vehicles were processed in batches of 25-30 per month across the four depot locations.
Customer Communication
The company updated its booking terms and vehicle handover process to include clear communication about the speed limiter:
- Booking confirmation: Noted that all vehicles are fitted with speed limiters as part of the company’s safety commitment
- Handover briefing: Explained the speed limiter function and the rationale — customer safety and vehicle characteristics
- Dashboard sticker: A simple notice confirming the vehicle’s maximum speed
Customer feedback on the speed limiter was overwhelmingly neutral to positive. A post-rental survey showed that 72% of customers rated the speed limiter as “reassuring” or “not noticed,” 24% as “no opinion,” and only 4% as “restrictive.” Several customers commented that they felt safer knowing the vehicle would not exceed a speed appropriate to its size.

Duty of Care Position
The company’s legal advisers reviewed the speed limiter deployment as part of a broader duty of care assessment. Their conclusion was that the voluntary fitment of speed limiters — configured below the legal maximum based on vehicle-specific risk factors — represented strong evidence of reasonably practicable risk management. Combined with the enhanced handover briefing, the company’s legal exposure was assessed as “materially reduced.”
What the Fleet Manager Said
“We are putting inexperienced people into large vehicles. That is the nature of our business. The question was always: what are we doing about the foreseeable risk? Before AutoKontrol, the honest answer was ‘not enough.’ Now we have a physical control that protects our customers, other road users, and the business. The insurance saving pays for it. The duty of care improvement is what lets me sleep at night.”

Key Takeaways
- Voluntary speed limiters in rental fleets address a foreseeable risk that briefings alone cannot manage
- Setting limits below the legal maximum based on vehicle characteristics demonstrates active risk management beyond minimum compliance
- Customer acceptance of speed limiters in rental vehicles is significantly higher than operators typically expect
- Insurance premium reductions are achievable when the speed management programme is evidence-based and the insurer can see compliance data
- The duty of care case for voluntary speed limiters in leisure vehicle rental is strong and strengthening as case law develops
- Off-season installation eliminates revenue impact and makes the programme operationally straightforward
