Police in southwest Iceland stopped two foreign drivers last week.
Both times, the cars were swerving erratically all over the road on the way to Keflavik International Airport. Both times officers expected the drivers to be drunk.
However, rather than being under the influence of alcohol, Iceland Magazine reports the drivers were so distracted by the northern lights they lost the ability to drive.
They simply were unable to keep their eyes on the road.
However, it's not just the aurora borealis causing traffic havoc.
