WSDOT Traction Advisories: How to Verify Your SeaTac Rental Meets Cascade Pass Winter Requirements

When winter storms hit the Cascades, the Washington State Department of Transportation enforces strict traction advisories on I-90 and US-2. Learn how to verify your SeaTac rental car meets the requirements.

When winter storms hit the Cascades, the Washington State Department of Transportation (WSDOT) enforces strict traction advisories on I-90 and US-2. As a responsible renter, it's essential to ensure your SeaTac rental car meets the necessary requirements to navigate these roads safely.

In this article, we'll guide you through the process of verifying your rental car's tire ratings and requesting an All-Wheel Drive (AWD) or Four-Wheel Drive (4WD) vehicle to comply with local laws.

Understanding Traction Advisories

The WSDOT issues traction advisories to ensure driver safety during winter conditions. These advisories require vehicles to have Mud and Snow (M+S) or All-Weather tire ratings to maintain traction on snowy and icy roads.

Verifying Tire Ratings

To verify your rental car's tire ratings, follow these steps:

1. Check the tire information placard on the driver's side doorjamb or inside the fuel filler door.

2. Look for the M+S or All-Weather symbol on the tire sidewall.

3. Check the rental car's documentation or consult with the rental company to confirm the tire ratings.

Requesting an AWD or 4WD Vehicle

If your rental car doesn't meet the traction advisory requirements, you can request an AWD or 4WD vehicle at the counter. Here's how:

1. Inform the rental company about your plans to drive on I-90 or US-2 during winter conditions.

2. Ask about the availability of AWD or 4WD vehicles in their fleet.

3. Request to upgrade to an AWD or 4WD vehicle, if available.

Additional Tips

* Always check the weather forecast and road conditions before embarking on your journey.

* Consider investing in snow chains or renting a vehicle with snow chains installed.

* Drive slowly and cautiously, even with proper tire ratings and AWD or 4WD capabilities.

By following these steps and tips, you'll be well-prepared to navigate the Cascade Pass during winter conditions. Remember to prioritize your safety and the safety of others on the road.
