Tips for Wet Roads
Rain is a factor in Hawaii driving. For your driving safety, here are some pointers to keep in mind:
- Keep your windshield clean. Otherwise, wiper blades may turn the first drops of rain into an oily smear, making visibility difficult during the day, and nearly impossible at night.
- Turn on your lights. Cars tend to "disappear" in rain, so use your parking lights to make your car more visible. In a downpour, use your headlights on their low beam. It's not only smart driving - many states require it by law!
- Turn on the fan. High humidity and rain go hand-in-hand, frequently causing your windshield to fog up. Your defroster blower will help clear everything up.
- Turn on your air conditioner. If you have air conditioning, turn it on to clear fog from both the windshield and windows.
- Close your windows. Some motorists mistakenly lower their windows to clear fog. However, other cars - running through puddles - can send a spray of water that often hits drivers in the face. It's not only distracting, it's dangerous.
- Watch out for the oily road slick that forms in new rain. During the first thirty minutes of rainfall, oil and dust on street pavements change to a slippery substance that's as slick as ice.
- Watch for running pedestrians. In heavy, sudden showers, people tend to cover their heads and begin running for cover. They don't see you, and since rain can sometimes make a good deal of noise, they may not hear you either.
- Keep one foot "at the ready." Throughout a rainstorm, be prepared to lift your foot off the accelerator at a moment's notice - that's likely all the notice you'll get!
- Be sensitive to the condition of your tires. If your tires are fairly new, reduce speed slightly. But if your treads are showing a bit of wear, quickly reduce your speed. Worn out or bald tires may have no grip at all on wet pavements.
- Beware of "puddles" on the road. At speeds of about 35 mph, tires may actually start to ride on top of the water - a phenomenon called "hydroplaning." The condition gets worse at higher speeds. When a car is hydroplaning, it is virtually out of control. If you sense hydroplaning, don't hit the brakes - lift off the accelerator immediately until you feel your tires "grip" the road again.
- Drive in the right lane. Generally, the right lane gets more traffic, which may help it dry sooner.
- Drive as though you have no brakes. Deep puddles sometimes soak brakes rendering them useless. After going through deep water, proceed cautiously, applying brakes frequently until they dry out.
- Trust your own eyes. A road full of smooth reflections that looks slippery usually is.
