Teach yourself to judge your car’s speed

Good drivers can accurately judge how fast they are travelling; they look at their speedo often just to check their judgement. Usually they find that they are only one or two km/h out. When their judgement is not accurate they know they need to be more careful because it’s a sign something is wrong.

If you can judge your speed accurately it’s easier to obey speed limits and drive safely. 

Here’s how you can teach yourself to judge your car’s speed:

  • Sit in the car where you can see the speedo. If you cannot see it at all ask the driver to tell you the speed
  • While the car is moving, look ahead as if you are driving. Look at least to the fifth car ahead of you, or about where you will be in five to ten seconds time. (Experienced drivers are always looking at least this far ahead and usually much further.)
  • Look at the speedo and notice the car’s speed. (Check that the speed you are seeing is the same speed the driver is seeing. This is important because the angle from which you view the speedo can make a difference in some cars.)
  • Keep glancing at the speedo and then look ahead. Soon you will begin to guess what the speed is before you glance at the speedo.
  • Every time the driver speeds up a little or slows down, guess the car’s speed and then look at the speedo (or ask the driver) to test your judgement. Practise this often until you get good at judging speed accurately.

If your driver is a good driver, you will notice that they never drive over the speed limit. Often you will see they drive much slower than the speed limit even when other drivers do not. This is because good drivers match their speed to the situation around them and keep crash avoidance space.
