4. Roadcraft and driving plan
Information and Observation
Introduction
The HPC driver displays
a high degree of advanced observation, seemingly anticipating the threat of
potential hazards well before they develop. Through a heightened sense of
visual acuity and concentration, all long range and short range hazards are
identified and prioritised as a basis of preparing and implementing the driving
plan. Observation also includes information gathered from all the main senses
of sight, touch, hearing and smell.
Competencies
- Ability to use long range observation and continual assessment to identify
all hazards, assess their threat and prioritise them in order of risk
- An awareness of zones of invisibility
- Display a comprehensive knowledge of the Highway Code and Roadcraft
Demonstration
- The driver will use a continual scanning process, from the horizon back
to the car, scanning to the sides and then to the rear in the process. This
process is a continual one and this visual sweep is also referred to as
'scanning and planning'.
- In demonstrating long range observation the driver will negotiate all
hazards (single and multiple) with the maximum safety margin. The driver
can be observed to react appropriately to all hazards in a timely manner,
and this may further be demonstrated by comments evidencing anticipated
future hazards.
- The driver will identify, and be able to distinguish between, zones of
visibility and zones of invisibility and react accordingly.
- The driver will show appropriate reaction to traffic signs and other information.
Hazard Management
Introduction
The Driving Plan, as defined by Roadcraft, should be the foundation of the
HPC drive, demonstrating
a proactive approach to all hazards whilst minimising risk at all times. The
plan should be applied in a logical and systematic manner, in accordance with
the System of Car Control as described within Roadcraft, with the flexibility
to adapt to changing circumstances. The HPC
driver will demonstrate early anticipation and assessment, leaving nothing
to chance, and will always seek to minimise risk and maximise safety.
Competencies
- Ability to negotiate hazards with a systematic and logical plan of action,
whilst minimising risk at all times
- Ability to maintain an ongoing assessment of risk
- Ability to clearly communicate intentions to other road users in an unambiguous
and timely manner
- Ability to create and manage a safe environment
- Always driving within the capabilities of the car and driver
Demonstration
- The car is in the correct position, speed and gear with an appreciation
of the prevailing driving environment and hazards.
- The driver displays the ability to anticipate the potential or actual
threat from all hazards and continually evaluate 'what if?' scenarios to
ensure there is always a contingency plan to respond to changes. The driver
never appears surprised or caught out by a hazard.
- The driver would be expected to demonstrate a consistent use of the system
of car control in the driving plan, with evidence of separation of the phases
of information, position, speed, gears and acceleration.
- Application of brakes to reduce the speed of the car should be made with
one progressive braking movement, avoiding multiple braking actions. The
appropriate gear should be selected for the speed and hazard, missing intermediate
gears where appropriate, providing optimum control to negotiate the hazard
whilst having the ability to accelerate away safely and progressively.
- The driver will show flexibility when applying the system of car control:
all phases of the system should be considered though not all may be relevant
for a given hazard. The driver should be able to react to the need for an
immediate change in the sequence of the plan in response to changing or
unexpected hazards.
- All signals will be given in sufficient time and be of adequate duration
to convey the appropriate message. Signals will be given when there is a
reasonable expectation that other road users will benefit from them and
the driver will look for a reaction to any signal from other road users
before committing to the next action.
- Drivers will have a responsible assessment of their capabilities, and
that of the car, and will maintain a reserve to deal with unexpected hazards.
Cornering and Positioning
Introduction
The HPC driver is expected
to position the car consistently, particularly for bends, in a manner that
affords optimum safety and stability, and minimises the threat to and from
other road users. There will be an optimum safety position and line for each
hazard and this should be demonstrated consistently throughout the drive.
Competencies
- Ability to position the car, on the open road, for maximum vision, greater
stability and increased safety margin
- Ability to analyse the limit point and determine the correct position,
line and speed as the limit point moves
- Ability to stop the car on one's own side of the road in the distance
that can be seen to be clear, and that can be expected to remain clear Display
an understanding of the cornering dynamics of the car and the selection
of the most stable line
Demonstration
- HPC drivers will position
the car on the approach to any corner for maximum visibility, relative to
the limit point of their vision, thus creating a greater degree of stability
and increased margin of safety. Drivers will show recognition of the requirements
to adapt their positioning to cater for the different hazards presented
by blind left hand bends, blind right hand bends, crests and dips, and a
sequence of bends. Positioning will take into account the nature of the
road (width, edges) and possible unseen hazards, such as pedestrians and
overtaking or oncoming motorcyclists.
- The driver should be able to describe the limit point of vision, and be
able to apply it such that the entry speed to a bend will be correct in
relation to that limit point, with proper use of appropriate acceleration
through and out of the bend.
- The driver will always have enough reserve to stop the car safely in an
emergency.
- The driver should be capable of balancing the car on the throttle so that
no further speed is lost from corner entry to acceleration point and the
car remains stable.
Overtaking
Introduction
- Overtaking is probably the most difficult skill to master and is potentially
the most dangerous manoeuvre undertaken when driving. The subject is therefore
covered in greater depth than other topics within this document.
- The ability to judge and execute a safe, courteous and systematic overtake
is an essential requirement of the
HPC driver. The driver will be able to gauge whether an overtake
is appropriate within the purpose of the journey, and the resultant successful
overtake is the product of good long term planning, excellent observation
and driver discipline. The driver should be aware of how others might perceive
overtakes, and allow for how they might react to the driver's actions while
an overtake is still being planned.
A typical overtaking manoeuvre comprises three stages:
- The Following Position
- The Contact Position
- The Overtake
The Following Position
The car is positioned at a safe distance from, and at a similar speed to,
the 'target' vehicle(s) whilst ensuring:
- ability to stop within the distance that is clear ahead
- not intimidating or pressurising the car in front
- the optimum vision ahead to allow the decision to be made as to when to
move into a 'Contact' or potential 'Overtaking' position
This position is used to determine the optimum overtaking strategy and, by
using the driving plan, to anticipate moving to stage 2 as any potential overtaking
opportunity emerges. This decision to move to the Contact position will be
influenced by, among other factors, the prevailing hazards, the action of
other road users and the proximity of speed restrictions ahead.
The Contact Position
Good forward planning and long observation is used to judge when a potential
overtaking opportunity may emerge. At that point the gap with the target vehicle
will be closed to a contact position some two to three car lengths behind
the target vehicle. The close is timed in relation to existing and anticipated
hazards, with particular reference to side hazards and zones of restricted
view. The contact position is inherently more risky as the safety margin is
reduced and the move to this position should be circumspect and judged with
precision.
If the vision ahead and the situation behind allows, the car is positioned
to the offside of the carriageway to obtain an uninterrupted vantage point
of the road ahead; only then can the decision be made to overtake. This extended
vantage point should be used judiciously; many other road users will be unfamiliar
with this positive positioning and the driver should be aware of the potential
reaction of other road users, both that of the target vehicle and any vehicles
behind that may attempt to close the gap just vacated. A driver should display
complete all around awareness and plan for such eventualities, and consider
using indicators to inform other road users of intention as appropriate.
From the extended vantage point all potential hazards can be evaluated from
the uninterrupted view ahead. If hazards prohibit an overtake for the foreseeable
future then the driver will return to the Following Position; if an overtake
is decided upon then stage 3…
The Overtake
Before committing to the overtake, the driver needs to be satisfied on certain
essential issues:
- Can the overtake be completed within half the distance that has been checked
as free of hazards, including those which may cause the target vehicle to
change course?
- Is it reasonable to expect that distance to remain free of hazards for
the duration of the overtake?
- Is the driver of the target vehicle aware of the intended overtake?
- Is the target vehicle stable, and likely to remain so?
- Is a warning signal required for the target vehicle, and what reaction
is needed?
- Is a signal required to convey intentions to other road users?
- Could any signal be misinterpreted?
- What speed differential is required to complete the overtake safely, without
causing problems to the driver of the overtaken vehicle and to other road
users?
- What contingencies are needed and available?
- The HPC driver will always
demonstrate self discipline and restraint; if there is any question of doubt
the decision will be made not to overtake.
Once a decision is made to overtake the manoeuvre can now be completed promptly
and in as straight and stable a line as possible. Speed and distance should
be judged to allow adequate clear visible road to pass before returning to
the nearside, in order to avoid causing inconvenience either to the target
vehicle by 'cutting in', or to other road users.
If appropriate the driver should consider the courtesy of acknowledging the
cooperation of the overtaken driver.
Finally, if there is any doubt, don't go!
Overtaking multiple vehicles
In assessing an overtake of more that one vehicle a driver would additionally
consider:
- How many vehicles can safely be overtaken?
- Is there a sufficient gap to return into after the overtake without heavy
braking, or causing other cars to brake?
- If part of a multi-stage overtake is there a sufficient 'stop-over' gap
to fall back into in case additional hazards may emerge?
- Is there a contingency plan if the existing 'stop-over' gap disappears?
- The actions and position of all other road users - for example is the
driver of one of the target vehicles likely to move out or change course
as the overtake is being executed?
Competencies
- Understand when an overtake is appropriate in the context of the planned
journey
- Ability to safely, consistently and accurately assess overtaking opportunities.
- Ability to accurately assimilate all relevant hazards in making a decision
whether to overtake, with particular attention to side hazards and driving
into zones of invisibility.
- Able to demonstrate a systematic overtaking technique.
- Able to position the vehicle for optimum vision and safety margin in the
preparation and execution of the overtake.
- Understand the increased risks of multiple overtakes and plan accordingly.
- Always be prepared for changing situations and to abort an overtake if
necessary.
Demonstration
- The driver should be able to explain the circumstances under which overtaking
might or might not be considered in relation to the purpose of the journey
and the prevailing environment. If there is no likelihood of overtaking
opportunities on a section of the journey, the driver should display a relaxed
attitude to the situation.
- The driver should show an understanding of when safe overtaking opportunities
are likely to arise in relation to the nature of the road, reacting to factors
such as signage, road markings and exits from bends.
- During the planning process the driver should show reaction to all hazards,
and factors that would become hazards if the car was positioned for an overtake.
- The driver should be able to explain the concept of, and be able to consistently
demonstrate, the three stage approach to an overtake as described above.
There should be clear evidence of distinction between the stages, such that
a passenger is aware of when the decision to overtake is made.
- The driver should be able to place the car for the optimum view, whilst
maintaining a safe and constant following distance.
- When considering overtaking a number of vehicles, the driver should show
an awareness of the increased, and potentially changing, hazards presented
by the situation. The driver should be able to state how many of the vehicles
it is safe to overtake, and what the contingencies are if the situation
should change.
- The driver should always demonstrate an attitude that safety is paramount,
and be prepared to abort an overtake if safety is compromised for any reason,
including misjudgement by the driver.
Multi-Lane Roads
Introduction
Motorways and other multi-lane roads present additional hazards with typically
high traffic density moving at high average speeds. The HPC
driver should be constantly aware of the knock-on effect that the actions
of a driver in one lane can have on traffic in other lanes, adopting a questioning
attitude to variations in traffic speed, and always maintaining a safety zone
around the vehicle. The driver should understand the importance of managing
concentration levels according to the conditions, and the effects of tiredness
creeping in.
Competencies
- Awareness of increased risk factors from high average speed and traffic
density
- Ability to monitor and assess the risks from all lanes, including from
the opposing carriageway
- Awareness of on-slips, hard shoulder vehicles etc, and adopting a safety
line
- Adopting a defensive position and managing space around the vehicle
- Ability to join, move across and leave carriageways smoothly and seamlessly
- Knowledge of the Highway Code applicable to motorways and dual carriageway
systems
Demonstration
- The HPC driver will be
aware of the higher average speeds on multi-lane roads and the need for
extended observation and more advanced planning, both ahead, behind and
to the sides. The driver should be able to describe the additional hazards
likely to be encountered, and show evidence of reaction to these.
- The driver will react appropriately where the actions of other drivers
can be predicted to affect the current driving plan, either directly or
by the effects on other traffic.
- The driver will how evidence of predicting and observing other traffic
joining or leaving the road, and react accordingly. The driver will also
react appropriately to the presence of vehicles on a hard shoulder. Where
crossings or other hazards exist on dual carriageways, the driver will show
evidence of awareness of the hazard by managing position and speed of approach.
- There will always be a safety zone around the vehicle, and that zone adjusted
to reflect the position of changing hazards.
- The driver will accurately judge speed and position when joining motorways
and dual carriageways, maintaining forward space in order to join the flow
of traffic safely and seamlessly without causing inconvenience to other
road users. When leaving, the driver will observe the nature of the exit,
particularly on dual carriageways, and give appropriate signals and adjust
speed in good time so as not to cause inconvenience to others.
- Drivers will show good lane discipline, using the overtaking lanes for
their intended purpose. Lane changes should be executed with good observation
and planning, effective use of signals as appropriate, and with minimal
inputs to steering and speed.
- The driver should be able to describe, and show appropriate reaction to,
the signs and surface markings used on these types of road.
Concentration
Introduction
The ability to manage concentration levels is essential and
HPC drivers will plan the drive to ensure they remain alert and
focused throughout. This topic also forms an essential part of the Attitude
and Behaviour section.
Competencies
- Possess a self-awareness to monitor personal concentration levels with
an understanding of the factors that adversely affect concentration
- Be able to manage concentration levels, and apply mindful attention according
to the situation
Demonstration
- HPC drivers will be aware
of their levels of concentration during the drive and should display self
awareness of factors that may lower concentration such as fatigue, physical
discomfort, mental attitude, stress, low blood sugar or timing of meals,
and the effects of food on the brain's functioning.
- The average prolonged concentration period will vary amongst individuals
but a driver should be aware of the need for regular rest breaks when planning
a drive.
- The driver should show the ability to manage levels of concentration and
awareness according to the prevailing risks, and not to be distracted by
focusing attention on factors that are not relevant to the immediate and
potential hazards.
Maintaining Progress
Introduction
- HPC drivers should seek
to maintain their chosen level of progress in a manner that is consistent
with, and determined by, the environment and all prevailing conditions.
They should recognise that they may have a higher skill level and possibly
be driving a higher performance car than the majority of other road users,
and with that comes an increased burden of responsibility to drive with
discretion and consideration.
- HPC drivers will have
the ability to cooperate unobtrusively and blend with other road users and
though their average speeds across country may be higher, all interactions
with other road users will be courteous and considerate.
Competencies
- Ability to judge safe progress, appropriate to the prevailing driving
environment and conditions
- Ability to merge with traffic flow unobtrusively and discreetly
- Display acceleration sense to consistently and accurately match speed
with available vision, relevant hazards and the Driving Plan
Demonstration
- At their chosen level of progress, HPC drivers
will always drive at a speed such that they can comfortably stop the car within the distance they
can see to be clear ahead. This maxim will always dictate the maximum speed for any given hazard,
though the actual speed may be much less.
- The driver will show recognition of changes in the nature of the road and the prevailing conditions
by appropriate variation in speed.
- HPC drivers will always interact with other road
users unobtrusively and ensure that any speed differential of their vehicle and other road users
never creates a hazard or is a cause for undue concern.
- The driver will recognise that a safe speed is determined by the prevailing hazards, and will
demonstrate an attitude that safety is always the overriding consideration.
