There are approximately 485,900 GB-registered heavy goods vehicles on UK roads. They make approximately 11% of all motorway traffic. When an accident involves a heavy goods vehicle, the consequences are typically severe — HGVs are involved in approximately a third of all fatal motorway accidents.

This guide brings together the latest verified figures on HGV and lorry accidents in the UK — covering the scale of the risk, the role of driver fatigue, the Driver CPC qualification, the evidence from London's Direct Vision Standard, and the ageing driver workforce. Every figure below is drawn from the published sources listed at the end.

Key facts and figures

  • ~485,900 HGVs are GB-registered and in use on UK roads.
  • 11% of motorway traffic is HGVs, yet they feature in roughly one-third of fatal motorway accidents.
  • 251 deaths in HGV accidents in 2019, alongside 1,111 serious injuries and 4,172 other injuries.
  • Over 40% of HGV road accidents involve driver error or reaction time as a contributing factor.
  • 29% of HGV drivers surveyed had fallen asleep at the wheel (4,000-driver Unite survey).
  • Only 10% of HGV accidents occur on motorways — most happen on A-roads and in urban environments.
  • 48.2 years is the average age of a UK HGV driver; 60% are over 44 and only 19% are under 35.
  • 35 hours of approved Driver CPC training is required every five years.

Key facts & figures (overview)

  • Approximately 485,900 GB-registered HGVs on UK roads
  • HGVs account for 11% of motorway traffic but are involved in approximately one-third of fatal motorway accidents
  • 2019: 251 HGV accident deaths, 1,111 serious injuries, 4,172 other injuries
  • Over 40% of HGV road accidents involve driver error or reaction time as a contributing factor
  • 8.1 HGV fatalities per million population
  • 29% of HGV drivers surveyed had fallen asleep at the wheel (based on a 4,000-driver Unite survey)
  • 2022: Fatigue was recorded in 38 HGV collisions (1.4% officially; estimated significantly higher)
  • Left-hand drive HGVs are more than three times more likely to be involved in accidents when overtaking or changing lanes
  • Only 10% of HGV accidents occur on motorways — the majority occur on A-roads and in urban environments
  • 2024 UK road fatalities: 1,602 (a 1% decline vs. 2023)
  • London DVS: 19 fewer deaths and 62 fewer serious injuries between 2022 and 2024
  • London KSI fell from an average of 71 per year (2017–2019) to just 35 in 2024
  • Average HGV driver age: 48.2 years
  • 60% of HGV drivers are over 44; only 19% are under 35
  • Driver CPC: 35 hours of approved training required every five years

The Driver CPC framework

The Driver Certificate of Professional Competence (CPC) is a mandatory qualification for professional HGV drivers in the UK. The requirement covers:

  • Initial CPC: Obtained as part of the HGV licence process
  • Periodic CPC: 35 hours of approved training every five years — equivalent to seven days over the five-year cycle

Driving an HGV without a valid Driver CPC is an offence carrying a fine of up to £1,000 per offence. Maintaining current competence is therefore both a legal requirement and a foundation of safer driving — and the same principle of keeping knowledge up to date applies to any workplace, which is why employers pair vehicle training with refresher courses such as our Risk Assessment Training.

HGV driver fatigue: the hidden killer

Driver fatigue is the most significant human factors issue in HGV safety. The Unite survey finding — 29% of HGV drivers had at some point fallen asleep at the wheel — was based on 4,000 lorry drivers and indicates the scale of the problem. Official statistics significantly undercount fatigue's contribution: in 2022, fatigue was officially recorded in only 38 HGV collisions (1.4% of the total), yet international research suggests 10–20% of all road collisions may be fatigue-related.

Key fatigue risk factors for HGV drivers include: long shifts and insufficient rest; night driving through the circadian low; monotonous motorway driving; employer and customer pressure to meet delivery targets; and inadequate roadside rest facilities. Managing tiredness and shift patterns is an occupational safety issue in its own right — explored further in our guide to shift work and fatigue statistics in the UK.

London's Direct Vision Standard: evidence that intervention works

The London Direct Vision Standard (DVS), introduced in 2021 and strengthened subsequently, provides compelling evidence that targeted regulation dramatically reduces HGV casualties:

  • KSI in London HGV collisions fell from an average of 71 per year (2017–2019) to just 35 in 2024 — a reduction of more than half
  • 19 fewer deaths and 62 fewer serious injuries in London between 2022 and 2024
  • The reduction was dramatically greater than the 4.5% improvement across the wider road network
  • HGV traffic volumes in London did not decrease — the improvement is attributable to the DVS standard

All HGVs over 12 tonnes in London are now required to have a minimum three-star DVS rating or fit Progressive Safe System measures.

The ageing driver workforce

The average age of a UK HGV driver in 2019 was 48.2 years. 60% were over 44; only 19% were under 35. The 2021 HGV driver crisis accelerated pre-existing demographic pressures. The structural challenge — insufficient younger drivers to replace retiring experienced ones — has safety implications as more inexperienced drivers enter the sector.
