The aim of the current study was to describe the accident and injury situations associated with cyclists. The study was based on information obtained from STRADA (Swedish Traffic Accident Data Acquisition), including the descriptions and details of the events leading up to the accidents. Travel data from the Swedish national travel survey was also utilised, enabling the risk situation for cyclists to be assessed. The most common accidents among cyclists were single accidents, accounting for 72% of all cyclists injured. Next most common, with 17%, were accidents involving motor vehicles, followed by accidents between cyclists, with 8%. The biggest influencing factor in the cause of single accidents was slippery surfaces, stated as a contributory cause in 23% of the accidents. Snow and ice were the main causes but loose grit, from winter maintenance, was also frequently given as a reason. Kerbstone edging, uneven road surfaces, collisions with temporary or permanent objects were also stated as the cause of many single accidents. Alcohol influence was another common contributory cause. The risk of being injured as a cyclist in traffic was as likely for both male and female genders. The highest risk groups were those of the young and the elderly.
