KIRKLAND, Wash. — Several vehicles were damaged by metal debris on southbound I-405 early Tuesday morning. 

Vehicles were forced to pull over on the side of the freeway near NE 116th Street shortly before 6 a.m. 

The Washington State Department of Transportation (WSDOT) originally estimated around 20 vehicles had flat tires. The Washington State Patrol told KING 5 later Tuesday morning around eight cars had tire damage from the debris.

WSDOT suspects the debris was from an unsecured load. Officials have not located who may be responsible for the road debris. 

Unsecured loads are illegal in Washington state. The law says "if an item falls off a vehicle and causes bodily harm, the driver faces gross misdemeanor charges and penalties of up to $5,000 and/or up to a year in prison."

Lawmakers have been pushing for tougher laws on unsecured loads.

In November, Rep. Christine Kilduff (D-University Place) pushed for renewed legislation that would force all commercial trucks to cover their loads. 

Kilduff said she would introduce a new bill during the 2020 legislative session. 

If you have any information on the incident or were driving nearby at the time, call the Washington State Patrol at 425-401-7788.
