Fall Driving Hazards

Sure, it's lovely out -- but be aware of the dangers of driving in autumn's quick-changing conditions

By Nigel Knowlton

When most drivers think of fall driving, they conjure up a near-idyllic driving experience complete with colorful fall foliage, empty highways and clear, cool days. Many fall days indeed live up to this classic description, but those picture-perfect days have a way of changing quickly during autumn.

Fall weather is often unpredictable and driving conditions can change from perfect to miserable within minutes. Additionally, during fall decreased daylight brought on by a return to Standard Time from Daylight Savings Time means that many of us will be commuting to and from work in darkness. Instead of being one of the better times of the year for driving, fall is actually one of the more treacherous times of the year to be on the highway. Vigilance is required if safety is to be maintained -- and the first place to start is in the driveway, before you hit the road.

Before starting on any trip, it is always a good idea to give your vehicle a pre-drive inspection. Make sure the tires are properly inflated and show plenty of tread, check to see all lights and turn indicators are working properly and make sure the engine has the correct fluid levels.

If you park your car outside, you've probably noticed that a warm body entering a cold car interior causes the windows to fog up. Clear all windows before you leave the driveway by running the defroster on high or wiping off the glass. Clean windows are essential for safety; even a small, fogged quarter window can severely limit visibility, especially when backing out into the street. Fog also tends to form on the exterior mirrors, so wipe those off while the other windows are clearing.

Once out on the highway, it is imperative to pay attention to weather and road conditions. Frosty patches, fog, black ice, rain, hail, sleet and falling leaves all present hazards to the unwary. Here's a checklist of fall driving hazards:

Bridges freeze first – During fall and winter months, bridges can be very dangerous. Because they are exposed to weather on both top and bottom, they will freeze over before the rest of the road, and you may not be able to tell until it is too late. Use caution when transitioning from the pavement to a bridge surface by steering smoothly, staying off the throttle and braking gingerly.

Frost – When Jack Frost visits your living room window the effect can be magical. When he visits a shady patch of highway around a blind corner, the effects are often deadly. Use caution if your driving route takes you over bridges, down tree-lined streets, or anywhere else shadows cross dew-laden highways.

Black ice – It's called black ice because it is invisible, as the black pavement underneath shows through and looks as dry as the rest of the road. Black ice usually forms below overpasses, on bridges, in shaded areas and where there is water running across the pavement. Because black ice is invisible, it is exceptionally dangerous and a driver who has been driving on clear pavement will be caught unaware. If you live in an area where frost occurs, black ice is always a possibility. Use extreme caution when driving on cold mornings where there is evidence of frozen moisture on the roadway.

Rain – Fall rainstorms often tend to be sudden and heavy. Early fall storms are the worst from a driving perspective because highways that have a summer's worth of oil and rubber buildup from traffic become extremely slick when suddenly soaked. It usually takes a couple of really good downpours to wash this buildup away and in the interim the roadway is especially hazardous.

Hydroplaning – Hydroplaning happens when excessive water buildup on the highway causes a vehicle to "float" on a layer of water. It occurs because the water buildup on the road is greater than the amount of water the tread channels can clear at a given moment. Usually, the hydroplaning lasts only a second or two as the vehicle is passing through a shallow puddle, but during heavy downpours the condition can be endemic. Because a hydroplaning vehicle has no direct contact with the road surface, it is difficult to impossible to steer and brake. In such conditions, slow down and avoid sudden movements of the wheel and quick stabs of the brake that can make your vehicle spin out of control. If you feel a floating feeling while driving on wet roads, steer straight and gently back off the throttle until you feel the tires make contact with road surface. In an especially heavy downpour, pull off the road and wait it out.

Fog – Usually found in low places or areas surrounded by trees, hills or mountains, fog is statistically the single most dangerous condition a driver can encounter. It can severely limit visibility and change your perception of distance. When encountering fog, even just a small foggy patch in a hollow, slow down. There may be a stalled or slow vehicle hidden behind that wall of white. It is also smart to turn on your headlamps (low beam) or fog lamps to increase your visibility and your chances of being seen by other motorists. Most accidents happen in fog because the driver was going too fast for conditions and rear-ended the vehicle ahead. Slow down to a crawl if necessary, keep your lights on and use extreme caution.

Leaves – As the fall season progresses, deciduous trees lose leaves that end up covering residential streets and country roads. While it is fun to blast through those colored leaves layering the highway, bear in mind that leaves can be slippery, especially when wet. Hard acceleration or braking, and sudden turns should be avoided when running over a pile of leaves, as they can lead to skidding. Additionally, like water, leaves often accumulate in low places. There may be a dip, pothole or other road hazard hiding under those leaves covering the roadway.

How Do Leaves Do It

Why do trees put on their spectacular fall show every year? Think of them as animals going into hibernation.

Leaves produce a chemical called anthocyanin that accounts for the striking reds and purples often found in the sugar and red maples, northern red oaks, sumacs and tupelos. As the weather gets cold, trees start shutting down their systems for winter. Nutrients move out of the leaves and into the tree trunk, branches and roots. The yellow and orange tones always present in leaves begin to show as the green of chlorophyll begins to disappear.

Eventually, trees shed their leaves to prepare for the deep sleep. As leaves continue to lose color and moisture, the wind picks them up and scatters them to the ground. Fallen leaves help contain warmth and moisture throughout the winter, thus protecting grasses and other plants until spring.
