The risk of motorcycle drivers having a fatal crash is five per cent higher on nights with a full moon and 32 per cent greater when there’s a supermoon, new research led by a 91�Թ� researcher has found.

Donald Redelmeier, a professor in the department of medicine at 91�Թ� and the lead author of the study , told the Washington Post that “our key recommendation is that extra care is needed when riding a motorcycle under a full moon.”

Some possible reasons for the increase: Full moons and supermoons could be a distraction for motorists, and the change in lighting could lead them to misjudge distance and speed.

Redelmeier told the Post that the broader lesson from the study is that if a full moon can have such an impact, imagine how distracting texting while driving is.

“The research serves as a safety reminder to the millions of people who ride a motorcycle, and the millions of others who do not, that small gaps in attention can lead to irreparable consequences," he said.

Redelmeier and co-author Eldar Shafir of Princeton University analyzed four decades of data from the official United States registry of motor vehicle crashes for the study.
