Feature |
Definition |
Qualification |
||||
Acceleration |
Act of causing the vehicle to gain speed by depressing the accelerator |
Accelerator should be depressed smoothly and progressively to avoid sudden and harsh acceleration which results in uneven jerky movements. |
||||
Actual time |
The actual time of the day in hours and minutes, when the yard and/or road test commenced. |
The examiner shall enter this time on the test report in the applicable block. |
||||
Approaching distance |
The distance from which the over-taking procedure is commenced in order to pass a stationary or moving hazard. |
The higher the speed, the greater the distance required from the stationary or moving hazard, when the overtaking procedure is commenced. |
||||
Attempt |
A single effort in one direction starting from an indicated position moving completely into another indicated area. |
In the case of parallel parking, two additional movements shall be allowed, once the vehicle is at least partially within a parking bay, but without leaving the parking bay completely during these two movements. |
||||
Blind spots |
Areas on either side of a vehicle not visible to a driver even with the aid of rear-view mirrors. |
Blind spots can only be eliminated by turning the head sufficiently in order to observe areas not otherwise visible - i.e. by looking over the shoulder to the left or right. |
||||
Braking |
Act of causing a vehicle to reduce speed by application of the service-brake. (Foot-brake) |
The service/foot brake should be applied timeously, smoothly and progressively using the right foot, without locking wheels while keeping both hands on the steering wheel in order that the vehicle is kept under control. Braking should, where possible, be applied on a straight course. A lower gear shall not be selected in order to replace or assist braking to reduce the speed of the vehicle. When braking is necessary it shall be completed before selecting a lower gear. |
||||
Bumps kerb |
When a wheel, tyre or any part of a vehicle comes into contact with the kerb |
|||||
Cancel signal |
See Signal ... cancel |
|||||
Clear space |
Areas surrounding the vehicle which allow manoeuvring room in which to take evasive action, if necessary. |
Clear space should be ensured around the vehicle when passing, overtaking, following, merging or stopping behind or alongside vehicles or objects. |
||||
Clutch ... control |
Using the clutch pedal to obtain clutch contact point, also known as friction point. |
This is when the fly-wheel, clutch/driven plate and pressure plate meet, which transfers engine power to the rest of the transmission in order to move. The clutch pedal should be released smoothly in order to obtain contact point without jerking. Clutch control shall be obtained for moving off and when changing gears. |
||||
Clutch ... coasting |
See Coasting |
|||||
... disengage |
See Disengage |
|||||
... rides |
Resting the foot on the clutch pedal whilst vehicle is in motion or keeping the clutch depressed whilst the vehicle is stationary for any length of time |
Since it causes excessive wear it should be restricted to situations requiring extremely slow speed such as for parking, stop-start traffic or where it could be justified. |
||||
... slips |
Holding the clutch at the friction point so that the power from the engine is only partially transmitted to the wheels. |
Since it causes abnormal wear it should be restricted to situations requiring extremely slow speed such as for parking, stop-start traffic or where it could be justified. |
||||
Coasting |
Driving a vehicle with the clutch depressed or in neutral, disconnecting the engine from the driving wheels. |
Since it reduces control of the vehicle and could cause undue wear of the clutch release bearing, it should be restricted to short distances just before coming to a standstill, where it could be justified. Neutral shall never be selected whilst the vehicle is in motion. |
||||
Collision |
Touching any moving or stationary hazard with a vehicle. |
Should any obstacle/object be touched, other than that for the specific manoeuvre being conducted, it shall be regarded as a collision. |
||||
Controlled stop |
Bringing a vehicle to a complete standstill, maintaining a straight course. |
Both hands should be on the steering wheel. Should the vehicle deviate from a straight course and corrective action is taken it is regarded as a controlled stop. Release pressure on the brake pedal as necessary if the wheels should lock. |
||||
Counter steer |
See Steering ... counter steer |
|||||
Cutting |
See Steering ... cutting |
|||||
Dangerous actions |
See Uncontrolled/Dangerous action |
|||||
Decelerate |
Causing a vehicle to reduce speed by releasing the accelerator only. |
The accelerator should be released timeously and gradually to ensure smooth reduction of speed. |
||||
Disengage |
Depressing the clutch pedal to disconnect the engine from the transmission. |
The clutch pedal should be depressed timeously and completely in order to select a gear or bring the vehicle to a standstill without stalling or labouring the engine. |
||||
Driving position |
The position directly behind the steering wheel which enables a driver to operate the controls of a vehicle safely and efficiently |
The distance from the steering wheel should preferably enable the knee to be slightly bent when the clutch is fully depressed. The arms should be slightly bent when the hands are placed in the twelve o’clock position on the steering wheel. |
||||
Duration |
The rounded off time of the "Stopwatch" time to full minutes for both the yard and road tests. |
|
||||
Emergency Stop |
Act of bringing a vehicle to a complete standstill, in the shortest possible distance. |
The foot/service brake should be applied as quickly as possible and the vehicle brought to a controlled stop in the shortest possible distance.
Both hands shall remain on the steering wheel until stationary. Should the vehicle deviate from a straight course and corrective action is taken it is regarded as a controlled stop. |
||||
Examiner |
An examiner for driving licences as contemplated in the Road Traffic Act |
A person who has been appropriately trained, graded, registered and appointed as an examiner for driving licences. |
||||
Fast |
See too fast |
|||||
Following distance |
The safe space to be maintained between one vehicle following another. |
It is determined when the rear of the vehicle ahead passes a fixed reference point - e.g.: lamp post, road sign, mark on the road etc., by the driver of the vehicle directly behind counting "2001, 2002". The front of the vehicle should not reach the same point of reference before this count is completed. Under adverse conditions such as rain, slippery surface, poor visibility, etc. the distance should be increased. |
||||
Gear changing |
Selecting of the gear which will allow the engine to operate at efficient RPM whilst the road speed of the vehicle suits the situation. |
The appropriate gear should be selected before moving off and before negotiating a hazard in order that the necessary acceleration can be applied. A lower gear should be selected to minimise the increase of vehicle speed on a decline or to maintain a suitable speed on an incline. The appropriate gear should be selected smoothly without grating and in accordance with engine speed, whilst keeping the eyes on the road. Having completed gear selection, the hand shall be returned to the steering wheel, and the foot then removed from the clutch pedal. Where possible gears should be selected whilst the vehicle is on a straight course. If braking is necessary, it should be completed before selecting a lower gear. |
||||
