The five keys give you:

Space for the vehicle;
Visibility for the driver;
Time to make decision.


The Five Keys are:
1) LOOK FAR AHEAD

Looking far ahead is indispensable if you want to drive in a straight line. At 50 KM. you must look at least one city block ahead. The faster you drive the farther ahead you must look; glancing regularly at the center of your lane or where you want the car to go will cause the car to follow your eyes. This same principle applies to turns, so you should look where you the car to go at all times. Also think far ahead, put your thoughts where your eyes are looking. Last, when backing up, you must turn your head and look backwards, towards the direction you want to go. Do not use your mirrrs to back up in a private passenger car.

2) GET THE BIG PICTURE

There exists in front of your car a fild of vision, which corresponds to the space necessary to stop or change direction: in the city it is sidewalk to sidewalk one city block in front of your ca; on the highways it is the soft shoulder to soft shoulder up to the horizon. To get a clear field of vision, you maintain your proper following distance: in the city, two seconds following distance; on the highway, three seconds; and in adverse conditions, four seconds. If you do not have a clear field of vision, cover the brake pedal with your right foot.

3) KEEP YOUR EYES MOVING

Do not stare at anything for any length of time for any reason. While driving, look all around in front of you. When there is a danger, cover the brake and then glance at the danger then look straight ahead. Never ever stare at the danger. Check your rearview mirrors every five to ten seconds. Always turn your head to check your blind spots before changing direction or lanes. Glance at the front wheels of other cars to verify their direction and future intentions.

4) MAKE SURE YOU ARE VISIBLE

During the night and in adverse conditions, put your headlights on but for maximum saftey, put your headlights on at all times when you drive. Try to get eye contact with other drivers and pedestrians. Use your signalling devices to get their attention. Whenever there is a danger, cover the brake and do not hesitate to toot the horn or give a headlight signal to get their attention. If you do not have eye contact with other people, brake and reduce speed immediately. Make sure your intentions are clear to the other users of the road. At night, you must signal the presence of your stalled vehicle with the proper lights or signals and you must movie it as far off the road as possible.

5) ALWAYS LEAVE YOURSELF AN OUT

An out is a space to go into when there is a danger. You will need space all around your car if you want to drive safly. Always have the proper following distance in front of your car. Another very important factor is the space on both sides of your car. You will need space on at least one side to swerve into avoid sudden obstacles in front of your car. If another car tailgates or follows too closely, increase your following distance, if you are on the left try to change to the right. If you are on the right, you slow down even more.更多精彩文章及讨论，请光临枫下论坛 rolia.net
