Safety Tips for Mountain Driving — Going-to-the-Sun Road offers some of the most spectacular mountain scenery in the United States, but it also presents unique driving challenges. Narrow lanes, sharp curves, steep drop-offs, and rapidly changing weather require drivers to stay alert and prepared.
Drive at a Safe Speed
Speed limits on the road are lower than on most highways for good reason. Stick to posted limits — often 25 mph or less — especially on curves and near drop-offs. The slower pace allows for safer maneuvering and more time to enjoy the views.
Use Low Gears on Descents
When going downhill, shift into a lower gear to help control your speed and reduce brake wear. Continuous braking can cause brakes to overheat, making them less effective.
Watch for Wildlife
Mountain goats, bighorn sheep, and even bears sometimes cross the road without warning. Stay vigilant, especially near blind curves and areas with dense vegetation.
Be Prepared for Sudden Weather Changes
Weather in the mountains can shift quickly. Fog, rain, and even snow are possible, even in summer. Keep headlights on in low-visibility conditions and adjust your speed accordingly.
Mind the Vehicle Restrictions
Large vehicles over 21 feet long or 8 feet wide are not permitted on certain sections of the road. These restrictions help ensure safety on the narrowest and most winding stretches.
Pull Over for Viewing
Never stop in the middle of the road to take photos. Use designated pullouts and parking areas to enjoy the scenery without blocking traffic or creating hazards.
Check Your Vehicle Before Driving
- Ensure brakes are in good condition.
- Check tire pressure and tread.
- Top off coolant and fuel — there are no gas stations along the road.
Final Advice
Patience and awareness are key when driving Going-to-the-Sun Road. Respect the terrain, be considerate of other drivers, and you’ll have a safe and unforgettable journey through Glacier National Park.
