When You Apply the Ipde Process You May Decide to

We use the IPDE (Identify, Predict, Decide, Execute) approach to driving to deal with potential and real hazards. IPDE defines the four steps involved.


The get-go footstep to good driving and avoiding collisions is to identify, well in advance, real and potential hazards.

From the thousands of objects in your field of vision, you must learn to filter out those that do non provide you with information relevant to the driving chore. For instance, although a red neon sign attached to a eating house may catch your eye, it’south an unnecessary distraction because it’due south irrelevant to the driving chore. Y’all must search for existent or potential hazards (such as traffic lights or children) and requite them your firsthand attention.

To utilise this data the run a risk must be spotted in plenty of time. That’s why your windows need to be articulate.


Pace ii is to predict what will happen should you encounter a real or potential risk.

Existent hazards

For a real hazard, such as a cherry-red light, stop sign or a stopped vehicle, y’all but predict whether or non the traffic low-cal will change or the vehicle volition remain stopped.

Yous usually see real hazards in plenty of time and will have few problems predicting what will happen. Although y’all may be scanning the road properly, a vehicle may all of a sudden stop right in front of you. You will then take to quickly predict what may happen in the next few seconds.

Potential run a risk

Every vehicle you share the route with is a potential run a risk. Be aware of where other drivers could get. Make your all-time prediction of what they’re likely to do and continue revising this prediction as you move towards them. Pedestrians, cyclists or children on the side of the route are often potential hazards.

Predict the path of potential hazards. The vehicle may make a right turn. The kid may run across the road.

The more often you lot practise predicting what may happen and what pedestrians and other drivers might practice, the quicker y’all’ll exist able to make accurate predictions.

Identify and predict


Step three is to decide exactly what you’ll exercise to bulldoze smoothly and deal with the hazard. This means planning your actions in detail and checking to see that the way is clear to proceed.

Existent hazards

Y’all may decide to simply brake gently or alter lanes to avert the hazard, or yous may want to brake hard, release the brakes and steer.

Potential hazards

When you encounter a potential hazard, you may make up one’s mind to take no action and continue to monitor the actions of other drivers, or you may decide to take action to avoid the other vehicles.

Consider the following steps before you take any activeness:

  1. Check that your chosen gate is still open.
  2. Check the surface status of the roadway for braking.
  3. Bank check the shoulder and the ditch.
  4. Go along to spotter the vehicle and decide whether you will accept action to avoid it.

The terminal step, to execute, means to behave out your decision.

Executing some of your decisions will just mean making a smooth stop at a traffic calorie-free.

Executing other decisions may involve using techniques for emergency driving.

To be good at executing your decisions, particularly emergency decisions, you need to practise in a safety situation, preferably with a trained instructor. Do helps you lot overcome the panic that normally arises the start time you’re in an emergency.

Decide and execute

When you lot begin practising the IPDE method y’all’ll be slow and will probably think in words. As you exercise, y’all’ll become faster and begin to think in ideas and pictures. At this stage, you will be able to deport out the entire procedure rapidly. You can cutting your reaction time past taking the time to practise the IPDE method. It may salve your life.

Once you have been using IPDE for some time, much of your identifying, predicting, deciding and executing will be carried out instinctively.

Y’all’ll demand to employ IPDE more often in heavier traffic and when you are driving at higher speeds.

Y’all’ll find that your concrete condition profoundly affects your ability to handle IPDE. If you’re tired or sick, you should reduce the IPDE load by travelling at reduced speeds. You lot tin can reduce the IPDE load by avoiding heavy traffic. Y’all might besides consider not driving.

Alcohol and other drugs make information technology very hard to carry out the IPDE procedure. Since IPDE is designed to foreclose you lot from having collisions, it’due south not surprising that a large number of crashes are alcohol-and drug-related.
