Pass Checker

Pass Checker shows live conditions for the mountain passes you'll cross today.

Heading over Snoqualmie before a storm? Crossing the Sierras? Driving through the Coast Mountains? Pass Checker pulls live road status, weather, and travel restrictions into one quick view — no scrolling through DOT websites or dodging ads to get the answer.

COVERAGE

• British Columbia — DriveBC-monitored highways (free, always)
• Washington — all WSDOT-monitored passes (free, always)
• Oregon, California, Nevada, Idaho, Montana, Wyoming, Utah, Colorado, New Mexico, Arizona
• Alaska and Hawaii

WHAT YOU GET

• Real-time pass conditions, sourced from state and provincial DOT APIs where available, with full attribution
• Live highway cameras for major passes
• Weather, temperature (°F or °C — pick your preference), visibility
• Travel restrictions: chain requirements, closures, oversized-vehicle limits
• Dark mode by default — easy on the eyes for early-morning drives
• Read Aloud — have conditions read to you while you pack the car or pull over, with voice / speed / pitch controls
• Adjustable text size for accessibility

NO ADS. NO TRACKING. NO ACCOUNT.

Pass Checker does not collect any personal data. There is no analytics SDK, no third-party tracking pixel, no required sign-in. The app talks to state DOT APIs and a thin backend that never sees who you are. The Data Safety section on this listing reflects that — no data collected, no data shared.

FREE FOREVER FOR WASHINGTON AND BRITISH COLUMBIA

WA and BC passes are free, always — no time limits, no ads, no sign-in. If Pass Checker helps you and you want to support development, Full Access ($4.99, one-time, no subscription) unlocks every other state and province as we add them.

A WORD ON SAFETY

Mountain pass conditions can change quickly. Pass Checker is built by a mountaineer who drives these roads, not a replacement for the agencies running them.
