Speed Limiters for HGVs & Lorries: Complete Guide

Heavy Goods Vehicles (HGVs) are the backbone of the UK economy, moving everything from food to construction materials across the country. Speed limiters are a legal requirement for every goods vehicle over 3.5 tonnes, and choosing the right system is essential for compliance, safety, and cost management.

This guide covers everything HGV operators need to know about speed limiters — from legal requirements to product selection and installation.

Legal Requirements for HGV Speed Limiters

All goods vehicles with a maximum gross vehicle weight (GVW) exceeding 3.5 tonnes must be fitted with a speed limiter set to prevent the vehicle exceeding 56mph (90 km/h). This has been a legal requirement in the UK since 1992.

The speed limiter must be EU/ECE R89 type-approved, sealed with tamper-evident seals, and accompanied by a speed limiter plate showing the set speed, installer details, and calibration date. The operator must maintain records of installation and calibration.

DVSA enforces these requirements through roadside inspections, annual testing, and operator premises visits. Non-compliance can result in prohibition notices, fines, and Traffic Commissioner action against the operator’s licence.

Why HGV Speed Limiters Matter

Beyond legal compliance, speed limiters deliver significant operational benefits for HGV operators.

Fuel savings are the most immediately quantifiable benefit. An articulated HGV travelling at 56mph instead of 65mph uses approximately 12-15% less fuel. For a vehicle covering 100,000 miles per year at 8.5 mpg, this represents approximately GBP 8,000-10,000 in annual fuel savings per vehicle.

Safety improvement is equally important. HGVs are involved in a disproportionate number of serious road accidents relative to their numbers on the road. The weight and size of an HGV means that even moderate speed reductions significantly reduce stopping distances and collision energy.

Insurance costs decrease when speed limiters are properly fitted and documented. Fleet insurers recognise the risk reduction and typically offer premium discounts of 5-15%.

Tyre, brake, and engine wear all decrease at lower speeds, reducing maintenance costs by an estimated 5-10%.

Product Options for HGV Operators

System 80 (DBW) Speed Limiter

The AutoKontrol System 80 is our flagship speed limiter for HGV applications. It uses Drive-By-Wire technology to provide precise speed control with +/- 1 km/h accuracy. EU/ECE R89 type-approved, tamper-evident sealed, and compatible with both 12V and 24V electrical systems.

The System 80 is the right choice for operators who need reliable, compliant speed limiting without additional fleet management features.

TrackSpeed (Speed Limiter + GPS Tracking)

For HGV operators who also need GPS tracking, driver behaviour monitoring, and fleet management, TrackSpeed combines the System 80 speed limiter with ScorpionTrack Fleet GPS tracking in a single device.

TrackSpeed includes GeoKontrol zone-based speed control, which allows operators to set different speed limits for different locations — for example, 10mph in a distribution centre yard, 30mph on approach roads, and 56mph on motorways. The transitions are automatic based on GPS position.

Installation Process

Installation is carried out by AutoKontrol-approved engineers through our Find & Fit service. The process for an HGV typically takes 2-3 hours and includes:

1. Vehicle assessment and speed sensor identification
2. Speed limiter module installation and wiring
3. Speed calibration using a rolling road or GPS verification
4. Tamper-evident sealing
5. Speed limiter plate installation
6. Documentation completion (installation certificate, calibration record)
7. Function testing

Our engineers travel to your depot or premises, so there is no need to transport vehicles to a workshop. For fleet rollouts, we can schedule multiple installations per day to minimise disruption.

Maintaining HGV Speed Limiter Compliance

Once fitted, speed limiter maintenance is straightforward:

• Daily walkaround: Check that the speed limiter plate is present and legible, and that tamper-evident seals are intact
• Periodic inspection: Include speed limiter checks in your planned maintenance schedule
• After mechanical work: If any work has been done to the vehicle’s gearbox, axle, or speed sensor, have the speed limiter recalibrated
• Record keeping: Maintain installation certificates and calibration records for every vehicle, and make them available for DVSA inspection
