Bikers and ATV drivers are getting aggressive on local highways during this Martin Luther King Jr. holiday weekend.
Police agencies across South Florida are trying to keep ahead of the packs that weave in and out of traffic, many times pulling wheelies.
It's can be scary for motorists, but dangerous for the bikers too.
An @OnlyInDade Instagram post includes video of a biker taking a bad spill on a causeway.
The biker's condition is unknown.
The "Wheels Up, Guns Down" events are supposed to call attention to gun violence, but that message is often lost in the chaos of the rallies.
