4- 4-1 Section 4 Y our Driving and the Road Here you’ll find information about driving on different kinds of roads and in varying weather conditions. W e’ve also included many other useful tips on driving. 4 - 2 Defensive Driving 4 - 3 Drunken Driving 4 - 6 Control of a V ehicle 4 - 6 Braking 4 - 9 Steering 4 - 1 1 Off - Road Recovery 4 - 12 Pa[...]

4-2 Defensive Driving The best advice anyone can give about driving is: Drive defensively . Please start with a very important safety device in your vehicle: Buckle up. See “Safety Belts” in the Index. Defensive driving really means “be ready for anything.” On city streets, rural roads or freeways, it means “always expect the unexpected.?[...]

4-3 Drunken Driving Death and injury associated with drinking and driving is a national tragedy . It’ s the number one contributor to the highway death toll, claiming thousands of victims every year . Alcohol affects four things that anyone needs to drive a vehicle: Judgment Muscular Coordination V ision Attentiveness. Police records show that al[...]

4-4 It’ s the amount of alcohol that counts. For example, if the same person drank three double martinis (3 ounces or 90 ml of liquor each) within an hour , the person’ s BAC would be close to 0.12 percent. A person who consumes food just before or during drinking will have a somewhat lower BAC level. There is a gender difference, too. W omen g[...]

4-5 But the ability to drive is affected well below a BAC of 0.10 percent. Research shows that the driving skills of many people are impaired at a BAC approaching 0.05 percent, and that the effects are worse at night. All drivers are impaired at BAC levels above 0.05 percent. Statistics show that the chance of being in a collision increases sharply[...]

4-6 Control of a V ehicle Y ou have three systems that make your vehicle go where you want it to go. They are the brakes, the steering and the accelerator . All three systems have to do their work at the places where the tires meet the road. Sometimes, as when you’re driving on snow or ice, it’ s easy to ask more of those control systems than t[...]

4-7 A void needless heavy braking. Some people drive in spurts -- heavy acceleration followed by heavy braking -- rather than keeping pace with traffic. This is a mistake. Y our brakes may not have time to cool between hard stops. Y our brakes will wear out much faster if you do a lot of heavy braking. If you keep pace with the traffic and allow re[...]

4-8 Here’ s how anti - lock works. Let’ s say the road is wet. Y ou’re driving safely . Suddenly an animal jumps out in front of you. Y ou slam on the brakes and continue braking. Here’ s what happens with ABS. A computer senses that wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work th[...]

4-9 Remember: Anti - lock doesn’t change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, you won’t have time to apply your brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even though you have anti - lock[...]

4-10 Suppose you’re steering through a sharp curve. Then you suddenly accelerate. Both control systems -- steering and acceleration -- have to do their work where the tires meet the road. Adding the sudden acceleration can demand too much of those places. Y ou can lose control. What should you do if this ever happens? Ease up on the accelerator p[...]

4-1 1 An emergency like this requires close attention and a quick decision. If you are holding the steering wheel at the recommended 9 and 3 o’clock positions, you can turn it a full 180 degrees very quickly without removing either hand. But you have to act fast, steer quickly , and just as quickly straighten the wheel once you have avoided the o[...]

4-12 Passing The driver of a vehicle about to pass another on a two - lane highway waits for just the right moment, accelerates, moves around the vehicle ahead, then goes back into the right lane again. A simple maneuver? Not necessarily! Passing another vehicle on a two - lane highway is a potentially dangerous move, since the passing vehicle occu[...]

4-13 Check your mirrors, glance over your shoulder and start your left lane change signal before moving out of the right lane to pass. When you are far enough ahead of the passed vehicle to see its front in your inside mirror , activate your right lane change signal and move back into the right lane. (Remember that if your right outside mirror is c[...]

4-14 A cornering skid and an acceleration skid are best handled by easing your foot off the accelerator pedal. If your vehicle starts to slide, ease your foot off the accelerator pedal and quickly steer the way you want the vehicle to go. If you start steering quickly enough, your vehicle may straighten out. Always be ready for a second skid if it [...]

4-15 Here are some tips on night driving. Drive defensively . Don’t drink and drive. Adjust your inside rearview mirror to reduce the glare from headlamps behind you. Since you can’t see as well, you may need to slow down and keep more space between you and other vehicles. Slow down, especially on higher speed roads. Y our headlamps can light u[...]

4-16 Driving in Rain and on W et Roads Rain and wet roads can mean driving trouble. On a wet road, you can’t stop, accelerate or turn as well because your tire - to - road traction isn’t as good as on dry roads. And, if your tires don’t have much tread left, you’ll get even less traction. It’ s always wise to go slower and be cautious if [...]

4-17 Driving too fast through large water puddles or even going through some car washes can cause problems, too. The water may affect your brakes. T ry to avoid puddles. But if you can’t, try to slow down before you hit them. CAUTION: W et brakes can cause accidents. They won’t work as well in a quick stop and may cause pulling to one side. Y o[...]

Never drive through water that is slightly lower than the underbody of your vehicle. If you can’t avoid deep puddles or standing water , drive thro[...]

4-19 City Driving One of the biggest problems with city streets is the amount of traffic on them. Y ou’ll want to watch out for what the other drivers are doing and pay attention to traffic signals. Here are ways to increase your safety in city driving: Know the best way to get to where you are going. Get a city map and plan your trip into an unk[...]

4-20 Freeway Driving Mile for mile, freeways (also called thruways, parkways, expressways, turnpikes or superhighways) are the safest of all roads. But they have their own special rules. The most important advice on freeway driving is: Keep up with traffic and keep to the right. Drive at the same speed most of the other drivers are driving. T oo - [...]

4-21 When you want to leave the freeway , move to the proper lane well in advance. If you miss your exit, do not, under any circumstances, stop and back up. Drive on to the next exit. The exit ramp can be curved, sometimes quite sharply . The exit speed is usually posted. Reduce your speed according to your speedometer , not to your sense of motion[...]

4-22 Highway Hypnosis Is there actually such a condition as “highway hypnosis”? Or is it just plain falling asleep at the wheel? Call it highway hypnosis, lack of awareness, or whatever . There is something about an easy stretch of road with the same scenery , along with the hum of the tires on the road, the drone of the engine, and the rush of[...]

4-23 If you drive regularly in steep country , or if you’re planning to visit there, here are some tips that can make your trips safer and more enjoyable. Keep your vehicle in good shape.

Include an ice scraper , a small brush or broom, a supply of windshield washer fluid, a rag, some winter outer clothing, a small shovel, a flashlight, a red cloth and reflective warn[...]

4-25 What’ s the worst time for this? “W et ice.” V ery cold snow or ice can be slick and hard to drive on. But wet ice can be even more trouble because it may offer the least traction of all. Y ou can get wet ice when it’ s about freezing (32 F; 0 C) and freezing rain begins to fall. T ry to avoid driving on wet ice until salt and sand cre[...]

4-26 If Y ou’re Caught in a Blizzard If you are stopped by heavy snow , you could be in a serious situation. Y ou should probably stay with your vehicle unless you know for sure that you are near help and you can hike through the snow . Here are some things to do to summon help and keep yourself and your passengers safe: T urn on your hazard flas[...]

4-27 CAUTION: Snow can trap exhaust gases under your vehicle. This can cause deadly CO (carbon monoxide) gas to get inside. CO could overcome you and kill you. Y ou can’t see it or smell it, so you might not know it is in your vehicle. Clear away snow from around the base of your vehicle, especially any that is blocking your exhaust pipe. And che[...]
