System of Car Control |
The system ofcar control is away of approaching and negotiating hazards that is safe, methodical and leaves nothing to chance. It involves careful observation, early anticipation and planning and a systematic use of the controls to maintain your vehicle's stability in all situations |
|
|
How System works |
The system of car control consists of processing information and 4 further phases - position, speed, gear and acceleration. Each phase develops out of the one before. Processing information is central, it runs through and feeds into all the phases. |
|
|
What is a hazard? |
Anthing that is an actual or potential danger. They can come singly or in clusters. We can think of them in 3 types: Physical features eg junctions, bends or road surface. Position or movement of other road users eg drivers, cyclists, pedestrians Weather conditions eg fog or icy roads |
|
|
What is actual danger? |
Actual danger is where the law or rule of the road puts the onus on the driver to make sure it is safe before continuing |
|
|
Potential danger? |
Where common sense or road sense suggests to the driver that certain safety precautions be taken before entering thedanger area |
|
|
Deciding what to do, planning? |
Adopt a course of action, taking account of: What you can see. What you can't see What you might reasonably expect to happen. Which hazards represent the greatest risk. What to do if things turn out differently from expected - contingency planning |
|
|
Red Mist |
Is a colloquial term used to describe the state of mind of a driver who becomes determined to achieve a some objective on the journey eg catching a vehicle in front or getting to an incident in the shortest time. Fixed attentionon a particular goal can lead to blindness to other potential hazards such as pedestrians or other vehicles at intersections. This means the driver is at best less able and at worst no longer capable of realistically assessing driving risk |
|
|
Acceleration Sense |
Is the ability to vary vehicle speed in response to changing road or traffic conditionsby accurate use of the accelerator, so that you use the brakes less or not at all. |
|
|
Causes of skidding |
Driving too fast for the circumstances Harsh acceleration Excessive or sudden braking Coarse steering |
|
|
Understeer |
The tendency of a vehicle to turn lessin response to a given turn of the steering wheel. The vehicle runs wide of its intended course |
|
|
Oversteer |
The tendency of avehicle to turn more in response to a given turn of the steering wheel. The rear of the vehicle steps out |
|
|
Vehicle stability |
A moving vehicle is most stable when its weight is evenly distributed, the engine is just pulling without increasing road speed and it is travelling in a straight line. |
|
|
Following position -keeping your distance increases yoursafety because: |
You have a good view & can increase it along both sides by slight changes of position. You can stop your vehicle safely if the driver in front brakes firmly without warning. You can extend your braking distance so the driver behind has more time to react. You can see when it's safe to move into the overtaking position. In wet weather you get less spray from the vehicle in front |
|
|
Key principles for safe cornering |
Correct position on the approach Travel at the correct speed for the corner Select correct gear for that speed Use the accelerator to maintain a constant speed through the bend. Be able to stop safely in the distance you can see to be clear on yourside of the road |
|
|
Limit point |
Is thefurthest point towhichyou havean uninterrupedview of theroad surface. It is where the right hand edge of the road appears to meet the left hand edge in the distance. |
|
|
Basic safety rule for overtaking |
Identify the gap in which you will return and the earliest point at which you can enter that gap. Can you reach this point before any oncoming vehicles seen or unseen come into conflict with you |
|
|
Exemption criteria |
The exemption can be claimed if observance of the provision would be likely to hinderthe use of the vehicle for the purpose for which it was beingused on that occasion |
