A truck hauling honeybees overturned on an Interstate 35 in Oklahoma, setting swarms of the insects loose along the highway.
It happened Tuesday afternoon just south of Pauls Valley, which is about two hours north of Dallas.
A sheriff's deputy captured video of the bees swarming his vehicle when he got there. The road was quickly cleared, but authorities cautioned drivers about the swarm.
Beekeepers and state troopers wore special suits to gather as many bees as possible.
After dark, the bees became aggressive so workers were forced to burn the hives and other debris.
One person was hurt in the crash.
