Tips for Bus Drivers
1. Overheating brakes are a major problem in mountain driving. If you find that you are constantly riding the brakes, shift to a lower gear. This is best accomplished prior to descending mountain roads. In general, a vehicle will require the same gear while traveling downhill as it would while traveling up the same road. Unless you are an experienced driver, it can be dangerous to shift to a lower gear once the vehicle has started the descent. Proper tire pressure is important to prevent heat build up on tires while negotiating the many curves on park roads.
2. Vapor lock, engine or transmission overheating, or radiator boil over can all be caused by long steady ascents. Usually a 30-minute cool down period will alleviate the problem.
3. Consider stopping at scenic vistas while traveling. Not only does this allow your passengers more opportunity to view the park, it also allows your brakes to cool while traveling downhill. Occasionally pulling over while traveling uphill will give other motorists an opportunity to pass and might prevent impatient drivers from passing at dangerous locations.
4. Weather in the mountains will vary with the elevation. The lower elevations will often be warm and clear. But at the higher altitudes it may be cool, raining, snowing, or foggy. Thick fog is more likely to occur in the early morning and at night. Falling rocks are common after heavy rains.
5. Buses are prohibited from idling engines in parking lots of developed areas.
