Objectives: (Day 3) isibility limitations in bad weather Students will understand visibility limitations in bad weather Students will understand unusually strong wind conditions Students will understand low water crossings different types of floods Students will understand different types of floods Students will understand driving in extreme hot and cold temperatures

Heavy Smoke, Rain, Fog or Snow In an instant, the following can occur: Smoke is evident ahead. Suddenly smoke and ashes from a large brush fire cover the road. It is sprinkling. A few moments later, rain is falling in a solid sheet. Snow is falling lightly. Two miles down the road, it becomes a whiteout. DO NOT WRITE THIS SLIDE

Visibility Limitations Reduce speed Make sure your headlights are on low beam (aimed at the road surface) to reduce the amount of light/glare reflected back at you Turn on your windshield wipers If necessary, turn on the defroster or air conditioner Driving in Bad Weather

Visibility Limitations in Bad Weather  Reduce speed, but NEVER stop in a travel lane  Turn on emergency flashers  Look for an exit from the highway

Visibility Limitations in Bad Weather stop beyond end of guard rail back up to outboard of the guard rail turn off all lights (WHY??) wait for the bad weather to pass If impossible to leave highway:

If your stopping distance is longer than your sight distance, you have created a high risk situation – slow down Visibility Limitations in Bad Weather Visibility Limitations in Bad Weather Stopping Distance Visibility Range Braking distances at 20 mph with conventional tires on different pavement conditions Ice feet Packed Snow - 60 feet Wet - 25 feet Dry - 20 feet

Unusually Strong Wind Conditions Strong winds create a problem called buffeting. Buffeting: To strike against forcefully This condition can occur on bridges and when being passed by large trucks. These wind gusts and blasts can cause total loss of vehicle control.

How To Respond to Wind Reduce speed. Grip the steering wheel firmly to maintain vehicle control. Leave extra space between your vehicle and other vehicles. Be prepared to counter steer. Stay off brake

Low Water Crossings

Nearly 50% of flash flood fatalities are vehicle related Search for flood prone areas: - highway dips - bridges - low areas Most vehicles will float Very little water on the road surface can cause loss of control

Low Water Crossings Driving too fast through water will cause the vehicle to hydroplane and lose contact with the road surface.

5 Types of Floods Coastal Flood Urban Flood River Flood Flash Flood Ice Jam

River Floods Occur seasonally when heavy rains fill rivers or Heavy rains from hurricanes or tropical systems

Coastal Floods Winds generated from tropical storms and hurricanes can drive ocean water inland. Earthquakes can also produce waves called tsunamis, sometimes referred to as tidal waves.

Urban Floods As land is converted from fields or woodlands to roads and parking lots, it loses its ability to absorb rainfall. Streets can become swift moving rivers.

Flash Flooding An arroyo is a water-carved gully or normally dry creek bed. Arroyos can fill with fast-moving water very quickly.

Ice Jams Floating ice can accumulate at a natural or manmade obstruction and stop the flow of water.

Extreme Temperatures O O O O O O

Hot and Cold Temperatures Vehicles are designed to operate in a wide range of temperatures, from very hot to extremely cold. However, these extreme conditions can cause stress to any vehicle part that is temperature sensitive.

Tires should be balanced, aligned, Tires should be balanced, aligned, the proper type, and have adequate tread - The legal minimum, 2/32 of an inch tread depth, is inadequate on wet surfaces Check tire inflation Check tire inflation - Check cold tire pressure regularly (noted inside driver’s door or in manual) Check radiator coolant, hoses, and connections Check radiator coolant, hoses, and connections Cold Weather Precautions

Cold Weather Checks Check heater, defroster Check heater, defroster and air conditioner system and air conditioner system Winterized windshield wiper fluid Winterized windshield wiper fluid Check drive belts for tension and wear Check drive belts for tension and wear Keep lights and glass areas clear and clean Keep lights and glass areas clear and clean Check windshield wiper blades Check windshield wiper blades

Tire inflation needs special attention Under inflated tires are subject to heat and pressure buildup, especially when driving for extended distances at higher speeds. Hot Weather Checks The air conditioner, radiator coolant hoses, connections, and drive belts need special attention. due to the extra load placed on these cooling systems.
