Donald Redelmeier Found Full Moon is Associated with Fatal Motorcycle Crashes

ITMA's Regional Director in North America, Dr. Donald Redelmeier recently published his work on BMJ to describe the relationship between the full moon and an increased risk of fatal motorcycle crashes. Although other potential confounders cannot be excluded from this relationship, it is worthy to be aware that motorcyclists are facing a higher risk of fatal crashes during a full moon. It is encouraged to ride with extra care under such a circumstance and appreciate the power of seemingly minor distractions at all times.

Important EU Document on Driver Fitness

The European Commission and its unit for Road Safety, DG MOVE, Unit C2 has recently published a new report that contains important aspects of medical driver fitness issues. It can be found on and is free to download.

It is a systematic quality assessment of papers and a review of the best scientific evidence of effectiveness for different approaches to training, testing and graduated licensing for Category B (car) drivers, graduated licensing for higher motorcycle categories, driving instructor competencies, and requirements on medical fitness to drive (including its relevance for older drivers). The primary focus of the reviews was on road safety outcomes.

The review was produced with international cooperation and the institutions included are Transport Research Laboratory (UK), SWOV (Netherlands), BASt (Germany) Monash University (Australia) and Loughborough University (UK). A short summary by Lars Englund can be found below.
