Some insects have put the sting back in driving.
Swarming bees have shut down a highway ramp in Delaware.
State police say as many as 20 million bees escaped when the tractor-trailer carrying them overturned near Newark.
Troopers say the driver and two passengers were able to get out of the vehicle, but were stung 50 to 100 times each and were taken to a hospital.
Troopers called in bee handlers, who were working with firefighters to disperse the insects.
