The Driver
- Internal and external pressures to driver faster than competence
The Vehicle
- Different vehicles have different handling characteristics
- When driving an unfamiliar vehicle allow time to get use to its controls and handling
Road, weather & traffic conditions
- When adapting speed anticipate and plan for potential as well as actual dangers
Speed limits
- Statutory speed limits set maximum permissible speed
- Safe speed determined by the conditions at the time
- At night, conditions of low visibility or high traffic statutory speed limit may be excessive.
- The onus is always on the driver to select a speed appropriate for the conditions
How speed affect the driver vision
- As you drive faster, the nearest point in which you can accurately focus moves away from you
- Foreground detail becomes blurred and observation becomes more difficult because you have to process more information in less time
- Scan further ahead, so that you gain more time to assess, plan and react.
Using Speed Safely
- The skill of driving safely at speed is not easily acquired
- Every driver has their own speed limit (highest speed at which they are safe and comfortable in any given situation)
- You should know what your speed limit is and never go beyond it
Overtaking
- Driving at high speeds may entail frequent overtaking
- Careful preparation, positioning, observation and judgement of speed and distance
- Adapt speed to circumstances
- The faster you go the less time you have to react and the more disastrous the possible consequences
Key Safety Points
- Do not drive at speed unless you are competent, and it is safe to do so
- Be familiar with the controls and the handling characteristics of your vehicle – use the controls smoothly
- High-speed driving requires maximum attentiveness – if you cannot achieve a high level of attentiveness because of fatigue or some other cause, do not drive
- Always drive so that you can stop within the distance you can see to be clear, by day or by night
- If you double your speed you quadruple your braking distance
