Sometimes, when it rains it pours and yes, it does get worse.

A tractor-trailer hauling radioactive clinical (medical) waste crashed last Saturday,  closing a portion of Nebraska Highway 2. The radioactive medical waste shifted into the semi’s cab when the driver braked to avoid another crash.

Though I’m not quite sure how a semi- can transfer its load into the drivers cab there are good reasons, now quite obvious to the people involved in this incident, or keeping the drivers compartment entirely separate from the load compartment in any vehicle carrying clinical or other hazardous wastes.
