Over the time period Focus on the vehicle 2008 to 2012, 983 fatal type, age, condition and collisions occurred associated vehicle on Irish roads factors which may have claiming the contributed to the lives of 1,077 collision. This report examines people. 867 of the fatal collisions which occurred during this time period.
Report is based on an analysis of the completed Garda investigation file where the full circumstances of the collisions are available. Access was granted by An Garda Síochána to the completed Investigation File produced for each collision. The file contains two main reports: • An Garda Investigation Report • Forensic Collision Investigation Report The RSA collected the data in the Garda National Traffic Bureau. This report provides an analysis of the data by collision, by vehicle and by contributory factor.

The majority of defective tyres were on cars (84.8%), however, four (6.1%) motorcycle collisions had tyre quality as a contributory factor
10.6% were 6% were a Over half (51.5%) of underinflated, some combination of the tyre condition on dangerously low excessively worn, the 66 vehicles were underinflated, wrong rated as excessively or size or fitted in the dangerously worn wrong direction
Combination of tyres and behavioural factors such as alcohol, drugs, speed, distraction, fatigue led to the final outcome of the collision. Three of the collisions involved no other reported behaviour (only the condition of the tyres) 1) the vehicle experienced a tyre blow-out, 2) the tyre was overinflated on a wet surface and lost control and 3) the tyre was underinflated and collapsed on cornering.
• The largest age group driving with defective, worn, over or underinflated tyres were 17 to 24 year olds (47%). • The county where most vehicles had defective tyres was Donegal (18.2%). Followed by Cork, Kerry and Wexford (9.1% each). • 21 of the 66 vehicles lost control on a bend. • The road surface was dry at the time of 41 (62%) of the 66 collisions involving defective, worn, under/overinflated tyres. • The majority (62.1%) of the 66 collisions occurred on a regional road.
Overall 111 people lost their lives and 30 were seriously injured in a collision where a vehicle factor was a known contributory factor. Tyres:
