Low tide warnings

Learn about when to avoid certain routes during low tides so you do not damage your vehicle from scraping or getting caught on the loading ramps.

At low tides, some of our loading ramps have a steep slope that causes an extreme angle for:

  • Trucks
  • RVs with a low ground clearance
  • Vehicles towing a trailer

People driving these vehicles should wait for a ferry when the tide is higher for safe clearance and to avoid damage to your vehicle. Below are the routes with low tide warnings.

Traction tires are a special type of tire

manufactured with at least 1/8 of an inch tread. Traction tires are usually marked with a mountain/snowflake symbol, the letters M+S or “All Season.”

Carry chains, practice before leaving

Requiring chains keeps traffic moving during storms rather than closing a pass or roadway.

Prep your car. Fill up your gas tank,

pack jumper cables, ice scraper, warm clothing, snacks and water.
