Long Distance Scanning for Truck Drivers

<< Back to All

long-distance-scanningLong distance scanning is a critical tool for truck drivers to travel safely. Everything takes longer in a tractor trailer, whether speeding up, stopping, or maneuvering around obstacles. Long distance scanning is all about maintaining a proper eye-lead time of 15 – 30 seconds. At 60 miles per hour that means the driver is looking between a quarter and a half mile down the road.

Long Distance Scanning Tips

  • Look 15-30 seconds ahead for proper eye lead time
  • Watch for slowing traffic and other hazards

Having an appropriate eye-lead time does a couple of things for the driver. First it gives him or her notice of what is happening in the road up ahead. If a vehicle is parked on the shoulder, drivers practicing long distance scanning will be able to adjust their speed and vehicle position to safely get around the vehicle on the shoulder. Likewise, if traffic comes to a sudden stop, these same drivers will have enough time to safely bring their vehicle to a stop and help those behind them do the same.

Another advantage of practicing long distance scanning is that drivers can see not only what is happening down the road, but they can also see what is happening directly in front of their vehicle. The peripheral vision of the human eye can see what is happening down, to the side, and in front, of a person. So while the driver’s central vision is focused 15 to 30 seconds ahead, the peripheral vision will keep them informed of what is happening directly in front of them. However, peripheral vision does not see upward. If a driver is only focusing on the vehicle directly in front of them, he or she will not be able to see what is happening down the road.

Long distance scanning is a critical skill for every professional driver. By maintaining a proper eye-lead time, drivers can see what is happening in the road up ahead and have time to make the necessary adjustments to keep themselves, and the motoring public, safe.
