If you’re headed to the passes, make sure to check for chain requirements.

The Washington State Patrol (WSP) is enforcing restrictions at Snoqualmie Pass, checking cars and trucks headed eastbound.

It’s a $500 fine if vehicles don’t comply with the chain requirements.

When the “chains required” sign is active, even four-wheel-drive or all-wheel-drive vehicles must have chains on. The state requires them on at least the two front or the two rear tires.

Studded tires don’t meet the chain requirements. Cars still need to chain up, if required.

“Officers and troopers will be doing chain enforcement,” Sergeant Rocky Oliphant, spokesperson for the WSP Commercial Vehicle Division, said. “If you do not have chains and you’re in a commercial vehicle, you will be pulled over, possibly ticketed, and for sure, turned around.”

Additionally, Oliphant provided a message for non-commercial drivers: Give those big rigs a lot of room. Don’t make sudden moves around them. Don’t be the reason for a truck losing control.

“Give semi trucks extra room,” he said. “A lot of things that we see, and this is something that I’ve tried to focus on a little bit more, is aggressive cars around trucks. Sometimes we have these aggressive cars. They cut off semi trucks. Those trucks don’t have as much space where they can stop.”
