The HOV lanes of I-395 have been shut down due to a jackknifed tractor trailer that struck the highway wall divide.

Police have blocked traffic because the truck is leaking fuel and they fear it might ignite. The fuel is coming from a 100+ gallon saddle tank, according to scanner traffic. A hazmat team is being dispatched to the scene.

A long line of northbound traffic is now at a standstill in the HOV lanes.
