Observations from the Agricultural Vehicle Road Accident Data
• Identified areas of higher casualty risk:– Other road users
• Right hand turns by agricultural vehicles, particularly for motorcyclists
• Cars colliding with the rear of agricultural vehicles (high differential speed)
• Disconnection of tractor and trailer
– Agricultural vehicle occupants• Agricultural vehicle rollover
• Collisions from behind on dual carriageways (HGVs at high differential speed).
• Ejection and contact injuries within the cab (Low level of belt use an important factor).
Agricultural Vehicle Road AccidentsCountermeasures for Industry consideration
– Right turns• Journey planning to avoid right turns. Improved direction indicators.• Improved junction layouts. Better signing.
– High differential speed• Improved conspicuity/warning. Use of three-point seat belt.• Collision warning/mitigation systems for other vehicles.• Reduced agricultural vehicle use on dual carriageways.
– Rollover• Further investigation of causes. Use of seat belt.• Occupant friendly interior cab design.
– Trailer disconnection• Better maintenance/enforcement.• Improved/standardised hitch design.
