1. Operator Compliance Risk Score
(OCRS)

2. What is the Operator Compliance Risk Scoring System?
Mechanism for Calculating Likelihood of Operator Non Compliance
A guidance tool introduced to ensure that effective targeting is carried out
A fair system - it treats each operator in the same way. There is an incentive for operators to either maintain the standards that are already maintained, or make improvements to procedures. Operators that achieve a good standard are likely to be stopped less often
The R in OCRS stands for Risk not Rating. OCRS is a risk based scoring system and is NOT a rating system for operators
Operator Compliance Risk Score informs VOSA examiners of the probability of an Operator Being Compliant

3. How will VOSA use OCRS?
OCRS will be used at the roadside to identify which vehicles should be checked.
Red - Full check to be carried out.
Amber - Full check to be carried out unless higher scoring vehicles available.
Green - No check unless either no other higher scoring vehicle or obvious defect or offence.
VOSA examiners will use a hand-held mobile compliance device into which they will key a registration number or operators licence information, which will display the relevant OCRS.

4. Each Operator has 2 Scores
Roadworthiness (mechanical)
Traffic (non-mechanical)

5. Roadworthiness Concerned with the condition of the vehicle
Two sets of data are used:
Vehicle Testing data captured at each first test and annual test (HGV’s only)
Vehicle Enforcement data captured at the roadside or fleet checks at operators premises.
Vehicle Encounter data at the roadside does not include Sifts.

6. Roadworthiness Scoring Process
For each Test Failure defect and prohibition defect a score is given
Each vehicle check/test counted as an Event
Operator scored on total defect score divided by total number of Events
Score is calculated weekly for a 2-year rolling period
total defect points
number of events
The Roadworthiness index score is calculated to be the average number of defect points per event.
VOSA calculates the index score by taking weekly extracts from their central data warehouse.
However OCRS scores are only summarised by monthly encounters, therefore a score in Aug, would be based on encounters from a 2 year period from July to July.
= index score

The table summarises points issued to vehicles for mechanical defects.
Points are higher at the roadside as the defect is deemed more likely to contribute to an immediate threat to road safety
Points are higher for Immediate than delayed defects and higher again for Significantly (‘S’) marked defects
S Marked defects are defects that have been identified as a sign of systemic maintenance failures, that could be avoided by a driver walk around check

8. Overall Traffic
Concerned with roadside inspections and VOSA prosecutions in relation to non-mechanical infringements.
Including Drivers’ Hours, Tachograph and overloading offences
The OCRS Overall Traffic is further broken down into a Drivers Hours Score and an Other Traffic Score to provide extra information to VOSA examiners.
VOSA prosecution data is not specified on Vehicle Encounter or Test History Reports

9. Traffic Scoring Process
For each traffic offence found at the roadside or at a fleet inspection or as part of a Prosecution an offence score is given.
Each roadside, fleet inspection and prosecution is counted as an event
Operator scored on total defect score divided by total number of Events
Score is calculated weekly for a 2-year rolling period
total offence points
number of events
Process is same as roadworthiness scoring process
= index score

Table shows examples of points allocated to traffic offences
PLS points show points given for a prosecution offence, Traffic Points DH are Drivers Hours offences and Traffic Points OTH are other traffic offences

11. How are points decided on for defects and offences?
Danger
Perceived danger and risk to road safety
Range 1-25
Penalty
Reflects the maximum statutory penalty set by Parliament
Priority Value
Reflect the public interest and policy objectives, e.g. Exhaust emissions do not make a vehicle unsafe mechanically but have significant effects on the environment
Range 1-10
Commercial
Reflects the perceived level of commercial advantage gained
Range 1- 10
Impact
Reflects the impact on enforcement investigation e.g. preventing or obstructing into other offences by deception or falsification
Rating
Is the sum of the factors above
Maximum 80
VOSA focus group decided on points for each offence based on the 5 factors
Impact focuses on offences that may need further resource issues, such as Fail to Produce offences, which may need intensive investigation.

12. Index Score Operator scores compared with Peers (HGV GB, PSV GB etc)
Scores converted to Relative Score in League Table format
Bottom 1 – 10% given score of 1
11 – 20% given score of 2 etc
Scores displayed on Hand-held Device with colour code
Red, Amber and Green (RAG)
Worst Operators (score 10) given Red indicator
Best Operators (score 1) given Green
Operators ordered from highest index score to lowest index score
All operators with index score of 0 are given a Relative score of Green 0
All other operators are split into 10 percentile groupings of index score and given the appropriate Relative score (Green 1 to Red 10)
Operators may change scores as operators around them may do better or worse
Operators are then colour coded to be able to show easily their level of compliance to VOSA examiners

13. Example of calculation of index score
A one vehicle operator is stopped at a VOSA roadside check and a Drivers Hours Offence (39 points) is found.
The Traffic Index Score is then calculated as number of total offence points (39) divided by number of total events (1) = 39
If the vehicle was then subsequently stopped at the roadside again by VOSA, but was found to be clear of any defects or offences, the operators score would reduce to:
Traffic Index Score 19.5 (39/2)

Current colour coding for Relative Scores of OCRS operators
Amber is larger on Traffic as VOSA has more robust scoring for roadworthiness because of addition of Test data.
Therefore Amber traffic operators would be targeted more on Traffic to be able to give VOSA more information on the operators level of compliance
RED

15. Historic vs. Predictive
Historic scores use previous data for that operator
Past roadside encounters
Vehicle test history
PLS cases
Predictive scores use previous data for operators with similar characteristics
Type of operator licence
Age of operator licence
Size of fleet
Predictive score will only be shown when no Historic score is available
Historic data is based on actual data that VOSA has on an operator in 2 year calculation period.
As soon as VOSA encounters an operator there score will change from predictive to Historic.

16. Remember: OCRS Scores are snapshots in time They are updated weekly
The information used goes back for 2 years
Your score could change even if your points do not – you could compare better or worse as the industry changes
You can get the following VOSA reports to help improve performance:

23. Improvements to OCRS data areas next 6-12 Months
Improvements to OCRS 6-12 Months
Include data from operator visits by VOSA examiners
Include data from roadside Dangerous Goods Inspections
Incorporate Graduated Fixed Penalty data.
Development of Non GB Vehicle risk scoring using the same scoring system as that used for GB vehicles
VOSA examiners will be indicating the status of an operator when carrying out visits. This status will be added into OCRS and will particularly benefit new operators who often have predictive scores which may not accurately indicate the actual risk the operator represents.
Currently the dangerous goods aspect of a roadside inspection is not taken into account in the OCRS scoring process. It is intended that the outcome of the dangerous goods aspect will be included as failure to comply with the requirements for the carriage of dangerous goods can have major implications in an incident.
The data from the issue of Graduated Fixed Penalties will be included into OCRS. As the offence levels will be graduated in line with the seriousness of the offence the associated points for that offence will in turn be graduated so that less serious offences receive lower points that more serious offences.
VOSA is actively developing the use of OCRS in relation to non GB vehicles. It will mean that non GB operators will be rated in the same way as GB operators. The information gained from the use of non GB OCRS will be used to actively target the worst offending non GB operators.

24. Increase priority area of Scoring Model for Drivers Hours offences
Proposed Changes to
Scoring Model
Increase priority area of Scoring Model for Drivers Hours offences
Possibly decrease priority area of Scoring Model for Weight offences.
Both subject to agreement from Department for Transport
VOSA will be consulting with the Department for Transport (DfT) in regard to the priority points allocated to certain types of offences.
In particular we will be establishing if there are any areas such as Drivers Hours that should be increased to recognise the increased risk caused by drivers who breach drivers hours regulations.
At the same time we will consult with DfT to establish if some offences should have the priority or safety value decreased. An example would be weight offences where overloaded vehicles are often within design weight.

This chart highlights the current relative scoring bands for OCRS operators, the Amber section is larger on the Traffic Side as VOSA currently has more roadworthiness data, which makes the Roadworthiness Score more robust
Therefore Amber is a larger band as VOSA will then encounter more of these operators at the roadside, which will give a clearer definition of their Traffic OCRS as we will have more data on them from the roadside.

VOSA proposes to amend the scores, so that the bands are the same for both scores types
As introduction of Graduated Fixed Penalties and Deposits will enable the Traffic Score to become more robust as VOSA will have more data to base the scores on
Amber 8 changed to Red 8 because VOSA data shows Amber 8 operators have similar prohibition rates to Red 9 & 10 operators
Also this will mean there are more red operators for VOSA to target.

27. Other OCRS developments
Improvements to OCRS 6-12 Months
OCRS Reports to be made available through portal
OCRS Frequently asked Questions to be updated
Specific article in Moving On to highlight the fact that OCRS is a system used by VOSA to target the most non compliant operators and should not be used on its own to rate an operator.
VOSA will be clarifying the definition of Sifts and depending on the definition be deciding if this should be included as a part of OCRS.
Operators will have on line access to VOSA’s Customer Information Portal
Portal will summarise each OCRS score for that operator, and give access to an operators Vehicle Encounter reports and Test History reports
These reports will show all Roadside and Annual Test encounters for an operator (including sifts) along with any defects/offences that were found and the OCRS points they attract
