Health & Safety Topic of the Month

June 2001

Drive Defensively

More than 41,000 people lose their lives in motor vehicle crashes each year and two million more suffer disabling injuries, according to the National Safety Council. The triple threat of high speeds, impaired or careless driving and not using occupant restraints threatens every driver -- regardless of how careful or how skilled.

Driving defensively means not only taking responsibility for yourself and your actions but also keeping an eye on "the other guy." The National Safety Council suggests the following guidelines to help reduce your risks on the road:

bulletDon't start the engine without securing each passenger in the car, including children and pets. Safety belts save thousands of lives each year!
bulletRemember that driving too fast or too slow can increase the likelihood of collisions.
bulletDon't kid yourself. If you plan to drink, designate a driver who won't drink. Alcohol is a factor in almost half of all fatal motor vehicle crashes.
bulletBe alert! If you notice that a car is straddling the center line, weaving, making wide turns, stopping abruptly or responding slowly to traffic signals, the driver may be impaired.
bulletAvoid an impaired driver by turning right at the nearest corner or exiting at the nearest exit. If it appears that an oncoming car is crossing into your lane, pull over to the roadside, sound the horn and flash your lights.
bulletNotify the police immediately after seeing a motorist who is driving suspiciously.
bulletFollow the rules of the road. Don't contest the "right of way" or try to race another car during a merge. Be respectful of other motorists.
bulletWhile driving, be cautious, aware and responsible.

Driving In the Rain

Losing control of your car on wet pavement is a frightening experience. Unfortunately, it can happen unless you take preventive measures.

You can prevent skids by driving slowly and carefully, especially on curves. Steer and brake with a light touch. When you need to stop or slow, do not brake hard or lock the wheels and risk a skid. Maintain mild pressure on the brake pedal.

If you do find yourself in a skid, remain calm, ease your foot off the gas, and carefully steer in the direction you want the front of the car to go. For cars without anti-lock brakes, avoid using your brakes. This procedure, known as "steering into the skid," will bring the back end of your car in line with the front. If your car has ABS, brake firmly as you "steer into the skid."

While skids on wet pavement may be frightening, hydroplaning is completely nerve-wracking. Hydroplaning happens when the water in front of your tires builds up faster than your car's weight can push it out of the way. The water pressure causes your car to rise up and slide on a thin layer of water between your tires and the road. At this point, your car can be completely out of contact with the road, and you are in danger of skidding or drifting out of your lane, or even off the road.

To avoid hydroplaning, keep your tires properly inflated, maintain good tread on your tires and replace them when necessary, slow down when roads are wet, and stay away from puddles. Try to drive in the tire tracks left by the cars in front of you.

If you find yourself hydroplaning, do not brake or turn suddenly. This could throw your car into a skid. Ease your foot off the gas until the car slows and you can feel the road again. If you need to brake, do it gently with light pumping actions. If your car has anti-lock brakes, then brake normally; the car's computer will mimic a pumping action, when necessary.

A defensive driver adjusts his or her speed to the wet road conditions in time to avoid having to use any of these measures!
