The System of Car Control

The Police Driver’s manual ‘Roadcraft’ states the system of car control is a way of approaching and negotiating hazards that is methodical, safe and leaves nothing to chance.  It involves careful observation, early anticipation and planning and a systematic use of controls to maintain your vehicle’s stability in all situations.

The system consists of processing information and four phases in sequence – position, speed, gear and acceleration.  Each phase develops out of the one before.  Information is central to the system.  One works through each phase in sequence.

The follows is a brief version of the system.

On approach to a hazard you will:

Process Information

Take information - check your mirrors

Give information – signal whenever it could benefit another road user

Position – position yourself so that you can pass the hazard safely and smoothly

Speed – Adjust your speed as necessary.  Use the accelerator or brake to give you the correct speed to complete the manoeuvre safely

Gear – Once you have the correct speed for the circumstances, engage the appropriate gear for that speed

Acceleration – Apply the correct degree of acceleration to negotiate and leave the hazard safely

Note the order of the sequence; most drivers find it difficult to reduce speed first and then select the appropriate gear, but with practice it will soon become a habit.

A more detailed description of the system can be found in ‘Roadcraft’ and the IAM driving manual ‘How the be a better driver – Advanced Driving the essential guide’
