To be a safe driver, you need all around your vehicle. When things go wrong, gives you time to think and to take action. To have space available when something goes wrong, you need to manage space. While this is true for all drivers, it is important for vehicles. They take up more space and require more space for and .
Of all the space around your vehicle, it is the area of the vehicle, the space you are driving into, that is most important.
The Need for Space Ahead. You need space ahead in case you must suddenly stop. According to accident reports, the vehicle that trucks and buses most often drive into is the one in of them. The most frequent cause is following too . Remember: If the vehicle ahead of you is smaller than yours, it can probably stop than you can. You may if you are following too closely.
How Much Space? How much space should you keep in front of you? One good rule says you need at least second for every feet of vehicle length at speeds below 40 mph. At greater speeds, you must add second for safety. For example, if you are driving a 40-foot vehicle, you should leave seconds between you and the vehicle ahead. In a 60-foot rig, you will need seconds. Over 40 mph, you would need seconds for a 40-foot vehicle and seconds for a 60-foot vehicle. (See Figure 2.12.)
To know how much space you have, wait until the vehicle ahead passes a shadow on the road, a marking or some other clear . Then count off the seconds like this: “one thousand-and-, one thousand-and-” and so on, until you reach the spot. Compare your count with the rule of second for every feet of length.
If you are driving a 40-foot truck and only counted up to two seconds, you are too . Drop back a little and count again until you have seconds of following distance (or seconds, if you are going over 40 mph). After a little practice, you will know how far back you should be. Remember: Add second for speeds above 40 mph. Also remember: When the road is slippery, you need more to stop.
